SPBM commands

ap-mode

Use ap-mode to configure the agreement protocol (AP) mode.

Use undo ap-mode to restore the default.

Syntax

ap-mode { both | multicast | off }

undo ap-mode

Default

AP is enabled for both unicast and multicast FDB entries.

Views

SPBM view

Predefined user roles

network-admin

Parameters

both: Enables AP for both unicast and multicast FDB entries.

multicast: Enables AP only for multicast FDB entries.

off: Disables AP.

Usage guidelines

AP prevents temporary loops that might occur when the topologies of SPBM neighbors do not match.

If AP is enabled, ISIS-SPB issues forwarding entries to the FIB tables in the data plane only if AP declares a topology match after LSDB synchronization is complete.

NOTE:

Do not confuse the "AP" in this document with access points, which are wireless access devices.

Examples

# Enable AP for multicast FDB entries.

<Sysname> system-view [Sysname] spbm [Sysname-spbm] ap-mode multicast

area-authentication send-only

Use area-authentication send-only to disable authentication for incoming ISIS-SPB topology advertisement packets (LSPs, CSNPs, and PSNPs).

Use undo area-authentication send-only to restore the default.

Page 6

Syntax

area-authentication send-only

undo area-authentication send-only

Default

ISIS-SPB authenticates incoming topology advertisement packets if area authentication (area-authentication-mode) is configured. The device accepts a topology advertisement packet only if the authentication method and password in the packet match its local authentication settings.

Views

SPBM view

Predefined user roles

network-admin

Usage guidelines

Before you change area authentication settings for an SPBM network, configure this command to prevent temporary authentication setting mismatch from causing topology advertisement packets to be dropped.

After you complete changing area authentication settings across the SPBM network, restore the default to authenticate incoming topology advertisement packets for security.

This command does not affect outgoing topology advertisement packets. When area authentication is enabled, outgoing ISIS-SPB topology advertisement packets always contain authentication information.

Examples

# Disable authentication for incoming ISIS-SPB topology advertisement packets.

<Sysname> system-view [Sysname] spbm [Sysname-spbm] area-authentication send-only

Related commands

area-authentication-mode

Use area-authentication-mode to configure area authentication.

Use undo area-authentication-mode to restore the default.

Syntax

area-authentication-mode { md5 | simple } { cipher cipher-string | plain plain-string }

undo area-authentication-mode

Default

Area authentication is disabled. No area authentication method or password is configured.

Views

SPBM view

Predefined user roles

network-admin

Page 7

Parameters

md5: Specifies MD5 authentication.

simple: Specifies simple authentication.

cipher: Sets a password in ciphertext.

cipher-string: Specifies the ciphertext form of the password, a case-sensitive string of 33 to 53 characters.

plain: Sets a password in plain text.

plain-string: Specifies the plaintext form of the password, a case-sensitive string of 1 to 16 characters. For security purposes, all passwords, including passwords configured in plain text, are saved in ciphertext.

Usage guidelines

ISIS-SPB area authentication guarantees that SPBM nodes learn topology data only from trustworthy neighbors.

For correct authentication, make sure the authentication method and password are the same across the SPBM network. ISIS-SPB sends these authentication settings in topology advertisement packets, including LSPs, CSNPs, and PSNPs. The recipients accept a topology advertisement packet only if the authentication settings in the packet match their local authentication settings.

To disable area authentication for incoming topology advertisement packets, use the

area-authentication send-only command.

Example

# Set the area authentication method to simple and the password to 123456 in plain text.

<Sysname> system-view [Sysname] spbm [Sysname-spbm] area-authentication-mode simple plain 123456

Related commands

area-authentication send-only

b-vlan

Use b-vlan to assign a B-VLAN to an SPB VSI.

Use undo b-vlan to restore the default.

Syntax

b-vlan vlan-id

undo b-vlan

Default

No SPB VSI is assigned a B-VLAN.

Views

SPB I-SID view

Predefined user roles

network-admin

Page 8

Parameters

vlan-id: Specifies a B-VLAN ID in the range of 1 to 4094.

Usage guidelines

An SPBM VSI can work only after it is assigned a B-VLAN.

You can assign only one B-VLAN to an SPBM VSI, but different SPBM VSIs can use the same B-VLAN.

For an SPBM VSI, you must specify the same I-SID and B-VLAN across all BEBs and BCBs.

Examples

# Assign B-VLAN 100 to I-SID 256.

<Sysname> system-view [Sysname] vsi vpn1 [Sysname-vsi-vpn1] spb i-sid 256 [Sysname-vsi-vpn1-256] b-vlan 100

bandwidth-reference

Use bandwidth-reference to configure the bandwidth reference for automatic link metric calculation.

Use undo bandwidth-reference to restore the default.

Syntax

bandwidth-reference value

undo bandwidth-reference

Default

The bandwidth reference is 40000 Mbps.

Views

SPBM view

Predefined user roles

network-admin

Parameters

value: Specifies a bandwidth reference in the range of 1 to 2147483648 Mbps.

Usage guidelines

ISIS-SPB automatically calculates a link metric value for an interface if neither global link metric value nor interface-specific link metric value is configured.

The following is the calculation formula:

Link metric value=(Reference bandwidth/Interface rate)x10

The value range for the link metric value is 1 to 16777214.

Examples

# Set the bandwidth reference to 200 Mbps.

<Sysname> system-view [Sysname] spbm [Sysname-spbm] bandwidth-reference 200

• spbm cost

bridge-priority

Use bridge-priority to configure the SPBM bridge priority.

Use undo bridge-priority to restore the default.

Syntax

bridge-priority priority

undo bridge-priority

Default

The SPBM bridge priority is 32768.

Views

SPBM view

Predefined user roles

network-admin

Parameters

priority: Specifies a bridge priority. It must be a multiple of 4096 in the range of 0 to 61440. For example, the bridge priority can be 0, 4096, or 8192. A lower value represents higher priority.

Usage guidelines

In conjunction with the system ID, the SPBM bridge priority forms the SPBM bridge ID. The SPBM bridge ID is a tie-breaker used in the ECT algorithms for choosing shortest paths.

Examples

# Set the bridge priority to 4096.

<Sysname> system-view [Sysname] spbm [Sysname-spbm] bridge-priority 4096

circuit-cost

Use circuit-cost to configure a global SPBM link metric value.

Use undo circuit-cost to restore the default.

Syntax

circuit-cost value

undo circuit-cost

Default

No global SPBM link metric value is configured.

Views

Page 10

Predefined user roles

network-admin

Parameters

value: Specifies a link metric value in the range of 1 to 16777215.

Usage guidelines

The following methods are available for you to assign a link metric value to an interface:

• Setting an interface-specific value in interface view.

• Setting a global value in SPBM view. This global value applies to all SPBM-enabled interfaces.

• Setting a bandwidth reference for the system to calculate a value automatically for the interface.

The system chooses a link metric value for an interface in order of interface-specific value, global value, and autocalculated value.

Examples

# Set the global SPBM link metric value to 11.

<Sysname> system-view [Sysname] spbm [Sysname-spbm] circuit-cost 11

Related commands

• bandwidth-reference

• spbm cost

control-address

Use control-address to configure the group MAC address for ISIS-SPB.

Use undo control-address to restore the default.

Syntax

control-address { all-cb | all-is | all-l1-is | all-l2-is | all-pb }

undo control-address

Default

The group MAC address for ISIS-SPB is 0180-C200-002E (all-pb).

Views

Parameters

all-cb: Sets the group MAC address for ISIS-SPB to 0180-C200-002F. This MAC address represents all

customer bridge intermediate systems.

all-is: Sets the group MAC address for ISIS-SPB to 0900-2B00-0005. This MAC address represents all intermediate systems.

all-l1-is: Sets the group MAC address for ISIS-SPB to 0180-C200-0014. This MAC address represents all Level-1 intermediate systems.

Page 11

all-l2-is: Sets the control MAC address to 0180-C200-0015. This MAC address represents all Level-2 intermediate systems.

all-pb: Sets the control MAC address to 0180-C200-002E. This MAC address represents all provider bridge intermediate systems.

Usage guidelines

ISIS-SPB uses a group MAC address for ISIS-SPB peer-to-peer communication. This group MAC specifies the destination MAC address for ISIS-SPB protocol frames.

Vendors might use different group MAC addresses. You can change the ISIS-SPB control MAC for interoperability in a multivendor network.

Examples

# Set the group MAC address for ISIS-SPB to 0900-2B00-0005 (all-is).

Predefined user roles

network-admin

network-operator

Usage guidelines

The fast-channel feature provides a quicker LSP propagation method than conventional LSP propagation. This feature spreads ISIS-SPB LSPs in the SPBM network by forwarding LSPs as data along the SPT in a dedicated SPB VSI. An SPBM node does not need to complete updating its LSDB before it propagates the topology change to the next node.

The I-SID for the fast-channel VSI is 255. To use the fast-channel feature, you must create a VSI and assign I-SID 255 to the VSI.

Examples

# Display fast-channel statistics.

<Sysname> display spbm fast-channel statistics Fast channel information for SPBM

--------------------------------VSI name : 1 B-VLAN : 1 I-SID : 255 State : Active Replication mode : tandem ECT algorithm : 00-80-c2-01 LSPs sent count : 10 LSPs received count : 20 LSP timer : 33 LSPs transmitted count: 5

Restart information for SPBM

---------------------------Restart status : Restarting Restart phase : LSDB synchronization Restart interval : 300 SA bit : Supported Total number of interfaces : 2 Number of waiting LSPs : 0 T2 remaining time : 284

Page 28

Command output

Field Descri

tion

Restart status

Restart state of the device:

• Restarting—The device is rebooting ISIS-SPB or performing an

active/standby MPU switchover. In this state, the device can forward traffic because its FIB is usable.

• Starting—The device is rebooting. In this state, the device cannot forward

traffic because the FIB is not usable.

• Complete—The GR process is complete. The device can forward traffic

normally.

Restart phase

Restart phase:

• Initialization—ISIS-SPB Graceful Restart is initialized.

• LSDB synchronization—Peer ISIS-SPB processes are synchronizing LSDBs.

• LSP stability—The local LSDB is converging.

• LSP generation—ISIS-SPB generates and floods LSPs.

• First SPF computation—ISIS-SPB performs the first SPF computation.

• Finish—SPF computation is finished.

Restart Interval

The maximum adjacency hold time (in seconds). If the restarting device fails to complete restarting before this timer expires, the peer ISIS-SPB process removes the adjacency with the restarting ISIS-SPB.

This timer is configurable with the graceful-restart t2 command.

SA bit

Support for setting the SA bit in the Restart TLV sent to the neighbor:

• Supported—The device performs the following actions:

○ When the FIB is not usable, the device sets the SA bit in the hello

messages so the neighbor will not advertise its adjacency with the restarting device.

○ When the routing table is usable, the device clears the SA bit in the

hello messages so the neighbor will advertise its adjacency with the restarting device.

• Not supported—The device clears the SA bit in the hello messages so the

neighbor will always advertise its adjacency with the restarting device.

Total number of interfaces Number of SPBM-enabled interfaces.

Number of waiting LSPs

Number of LSPs that are waiting to be synchronized with the GR helper for completing LSDB synchronization.

T2 remaining time

The remaining time (in seconds) of the T2 timer.

If the restarting device fails to complete restarting before this timer expires, the neighbor removes the adjacency with the restarting device.

T1 remaining time

Remaining time (in seconds) of the T1 timer on the interface.

The T1 timer sets the interval for the restarting device to retransmit hello messages with the RR bit set (restart request messages). The T1 timer is not user configurable.

The restarting device retransmits a restart request message to the neighbor if it does not receive an acknowledgment for a restart request (hello message with the RA bit set) before the T1 timer expires.

RA received

Whether the interface received an ISIS-SPB hello with the RA flag from the neighbor device.

Page 29

Field Description

CSNP received Whether the interface received a CSNP from the neighbor device.

T1 expirations

Number of T1 timer expirations on the interface. When this counter reaches 10, the restarting device stops retransmitting hello messages with the RR bit set.

Predefined user roles

network-admin

Parameters

ect-index: Specifies an ECT algorithm index in the range of 1 to 16.

vlan-id-list: Specifies a space-separated list of up to 10 B-VLAN items. Each item specifies a B-VLAN ID

or a range of B-VLAN IDs in the form of vlan-id1 to vlan-id2. The value range for B-VLAN IDs is 1 to

4094. The ID for vlan-id2 must be equal to or greater than the ID for vlan-id1.

Usage guidelines

An ECT algorithm represents a set of tie-breakers for calculating SPTs. For more information about the ECT algorithms, see IEEE 802.1aq SPB.

To improve link efficiency in an SPBM network, you can distribute traffic of B-VLANs along different paths by mapping B-VLANs to different ECT algorithms.

To ensure correct SPT calculation for a B-VLAN, the B-VLAN to ECT algorithm mappings must be the same across the SPBM network for B-VLANs that are in use. If two neighbors map a B-VLAN to different ECT algorithms, the link between them cannot transmit data traffic for the B-VLAN.

Examples

# Map B-VLAN 100 through B-VLAN 200 to ECT 2.

encapsulation s-vid vlan-id [ only-tagged ]

Page 57

Views

Ethernet service instance view

Predefined user roles

network-admin

Parameters

default: Matches all traffic that does not match any other Ethernet service instance on the interface. On

an interface, you can configure this criterion only in one Ethernet service instance.

tagged: Matches all frames that have an 802.1Q VLAN tag.

untagged: Matches all frames that do not have an 802.1Q VLAN tag.

s-vid vlan-id: Matches frames that are tagged with the specified outer VLAN ID. The vlan-id argument

specifies a VLAN ID in the range of 1 to 4094. If the outer VLAN is not the PVID, the matching result does not differ, whether or not you specify the only-tagged keyword. If the outer VLAN is the PVID, the matching result depends on whether or not the only-tagged keyword is specified.

only-tagged: Matches only PVID-tagged frames. To match both untagged frames and PVID-tagged frames, do not specify this keyword.

NOTE:

The outer VLAN refers to the C-VLAN for a single-tagged frame and the S-VLAN for a double-tagged frame.

Usage guidelines

The match criteria in each Ethernet service instance on an interface must be unique. For example, you cannot configure the encapsulation tagged command in one Ethernet service instance if another Ethernet service instance already contains this command. The VLAN ID specified with the encapsulation s-vid vlan-id command cannot be the same for any two Ethernet service instances on the interface.

An Ethernet service instance can contain only one matching criterion. To change the match criterion, you must remove the original criterion first. When you remove the match criterion in an Ethernet service instance, the association between the service instance and the VSI is removed automatically. For an Ethernet service instance to match frames from a VLAN on an interface, you must first create the VLAN and assign the interface to the VLAN.

If an Ethernet service instance contains the encapsulation default match criterion, traffic is matched as follows:

• The service instance matches all frames if it is the only instance on the interface.

• The service instance matches frames that do not match any other service if it is not the only instance

on the interface.

Examples

# Configure service instance 1 on FortyGigE 1/0/1 to match packets that have an outer VLAN ID of

111.

Parameters

flood-count flooding-count: Specifies the maximum number of LSPs that can be rapidly flooded before

SPF computation is started. The value range for the flooding-count argument is 1 to 15. The default value is 5.

max-timer-interval flooding-interval: Specifies the delay before fast flooding is performed. The value range for the flooding-interval argument is 10 to 50000 milliseconds. The default value is 10.

Usage guidelines

Fast flooding of LSPs enables ISIS-SPB to flood the first several LSPs that invoke SPF before SPF computation is started. This mechanism improves ISIS-SPB convergence time.

The number of fast flooded LSPs is specified by the flooding-count argument.

Parameters

is-name: Assigns a hostname to the device, a string of 1 to 64 characters.

Usage guidelines

ISIS-SPB uses a 6-byte system ID to represent a node in the network. This representation method is difficult for administrators to identify devices when they examine ISIS-SPB adjacencies, FDB entries, and LSDB entries.

Dynamic hostname exchange enables you to assign a symbolic hostname to each SPBM node. ISIS-SPB advertises this information in the Dynamic hostname TLV in LSPs to remote LSDBs.

Usage guidelines

SPBM supports head-end replication and tandem replication for broadcast, unknown unicast, and unknown multicast traffic.

• Head-end replication—Replicates frames at the ingress BEB for frames to enter the SPBM network.

This method is suitable for SPBM VSIs that have sparse multicast traffic. It does not require BCBs to maintain multicast FDB entries.

Page 63

• Tandem replication—Replicates frames only at the node where the shortest path tree forks. This

method is suitable for SPBM VSIs that have dense multicast traffic. It requires BCBs to maintain multicast FDB entries.

Head-end replication is suitable for service instances that have sparse multicast traffic. Tandem replication is suitable for service instances that have dense multicast traffic.

Predefined user roles

network-admin

Usage guidelines

By default, the device uses one B-VLAN to transmit both unicast and multicast traffic. If tandem replication is used, you must enable the multicast VLAN feature for the device to use separate VLANs for unicast and multicast traffic.

If the multicast B-VLAN feature is enabled, you must assign an odd B-VLAN ID to an I-SID for SPBM to transmit unicast traffic. SPBM automatically chooses the next higher even B-VLAN ID (odd B-VLAN ID plus 1) for multicast traffic.

ISIS-SPB only advertises the odd B-VLAN IDs. It uses the odd B-VLAN IDs when populating the unicast FDB table with routes. When populating the multicast FDB table with routes, it uses the even B-VLAN IDs.

When you use the multicast B-VLAN feature, follow these restrictions and guidelines:

• You must enable or disable the multicast B-VLAN feature on all nodes in the SPBM network.

• You must map both odd B-VLAN ID and even B-VLAN ID to MSTI 4092, and assign all ports on the

path of the two VLANs to the VLANs.

• Assign the odd B-VLAN ID for unicast traffic to the I-SID when you use the b-vlan command. The

device will automatically assign the even B-VLAN ID to the I-SID for multicast traffic.

Page 68

Parameters

on-startup: Sets the overload bit when the system starts up.

start-from-nbr system-id [ timeout1 [ nbr-timeout ] ]: Sets the timers for controlling the overload bit state

during the process of adjacency establishment. The nbr-timeout timer starts when the device starts up. If the device fails to establish an adjacency with the neighbor identified by system-id before the timer expires, the overload bit is cleared. If adjacency establishment is complete before the timer expires, the timeout1 timer starts. The overload bit is set before the timeout1 timer expires. When the timeout1 timer expires, the overload bit is cleared.

• system-id: Specifies a neighbor by its system ID in XXXX.XXXX.XXXX format.

• timeout1: Sets the delay to clear the overload bit, in the range of 5 to 86400 seconds. The default

value is 600 seconds.

• nbr-timeout: Sets the adjacency setup timer in the range of 5 to 86400 seconds. The default value

is 1200 seconds.

timeout2: Specifies the amount of time for the overload bit to be set since the system startup. The value range for this argument is 5 to 86400 seconds. The default is 600 seconds.

Usage guidelines

ISIS-SPB sets the overload bit in LSPs to notify its neighbors that it is experiencing an LSDB error condition and cannot forward traffic correctly. During path calculation, ISIS-SPB does not choose a path as the shortest path if the path includes the device that has the overload bit set.

You can set the LSDB overload bit when the device cannot record complete topology data in the LSDB for memory insufficiency or any other problems.

Parameters

i-sid: Specifies an I-SID for the VSI, in the range of 255 to 16777215.

Usage guidelines

You must assign a unique I-SID to each SPB VSI for identification. The name of an SPB VSI can be different on different SPBM nodes, but its I-SID must be the same across an SPBM network. For more information about VSIs, see MPLS Configuration Guide.

You can configure one SPB I-SID and one PBB I-SID for an VSI, but the two I-SIDs cannot be the same. For more information about PBB, see Layer 2—LAN Switching Configuration Guide.

The I-SID for the fast-channel VSI is 255. To use the fast-channel feature, you must create a VSI and assign I-SID 255 to the VSI. You cannot associate an Ethernet service instance with the VSI that uses I-SID 255 for data transmission.

Usage guidelines

Before you change adjacency authentication settings on a link, configure this command to prevent temporary authentication setting mismatch from causing loss of adjacencies.

For security purposes, restore the default to authenticate incoming ISIS-SPB hello packets after you change adjacency authentication settings on the link.

This command does not affect outgoing ISIS-SPB hello packets. When adjacency authentication is enabled, outgoing ISIS-SPB hello packets always contain authentication information.

Parameters

md5: Specifies MD5 authentication.

simple: Specifies simple authentication.

cipher: Sets a password in cipher text.

Page 72

cipher-string: Specifies the ciphertext form of the password, a case-sensitive string of 33 to 53 characters.

plain: Sets a password in plain text

Usage guidelines

ISIS-SPB adjacency authentication guarantees that SPBM nodes establish adjacencies only with trustworthy neighbors.

For correct authentication, make sure the authentication method and password are the same between SPBM neighbors. ISIS-SPB sends these authentication settings in hello packets. The recipients accept a hello packet only if the authentication settings in the packet match their local authentication settings.

To disable adjacency authentication for incoming ISIS-SPB hello packets, use the spbm authentication

send-only command.

Examples

# Set the adjacency authentication method to simple and the password to 123456 in plain text on interface FortyGigE 1/0/1.

Parameters

value: Specifies a link metric value in the range of 1 to 16777215. If the link metric is set to 16777215, the link will not be used for transmitting data traffic even if the adjacency is up.

Usage guidelines

The following methods are available for you to assign a link metric value to an interface:

Page 73

• Setting an interface-specific value in interface view.

• Setting a global value in SPBM view. This global value applies to all SPBM-enabled interfaces.

• Setting a bandwidth reference for the system to calculate a value automatically for the interface.

The system chooses a link metric value for an interface in order of interface-specific value, global value, and autocalculated value.

Parameters

seconds: Specifies an interval in the range of 3 to 255 seconds.

Usage guidelines

ISIS-SPB sends hellos over links to establish and maintain adjacencies between SPBM nodes.

A short interval improves network convergence time, but it requires more system resources.

The maximum adjacency hold time is 65535 seconds. If this value is exceeded, the original hello interval remains unchanged.

Examples

# Set the ISIS-SPB hello interval to 20 seconds on FortyGigE 1/0/1.

Parameters

value: Specifies a multiplier in the range of 3 to 1000.

Page 75

Usage guidelines

Adjacency hold time specifies the amount of time for one SPBM node to retain the adjacency with another. This timer determines how quick it takes for an SPBM node to detect a failed link.

The adjacency hold time equals the hello interval multiplied by the hello multiplier.

An SPBM node sends its adjacency hold time in hello packets to update the adjacencies with its neighbor. The neighbor removes the adjacency with the advertising node and recalculates routes, if it does not receive a hello packet before the timer expires.

The maximum adjacency hold time is 65535 seconds. If this value is exceeded, the original hello multiplier remains unchanged

Examples

# Set the hello multiplier to 6 on FortyGigE 1/0/1.

Parameters

spsource-id: Specifies an SPSource ID in the range of 1 to 1048575.

Usage guidelines

Each SPBM node has a multicast address for each SPB VSI. This multicast address consists of one shortest path source identifier (SPSource ID) and one I-SID. The I-SID identifies an SPB VSI, and the SPSource ID identifies the node as a multicast source in the SPB VSI.

The SPSource ID must be unique in the VSI.

network-admin

Parameters

maximum-interval: Specifies the maximum LSP generation interval in the range of 1 to 120 seconds.

minimum-interval: Specifies the minimum LSP generation interval in the range of 10 to 60000

milliseconds. This setting must be smaller than the maximum interval.

incremental-interval: Specifies the base number for the incremental interval. The value range is 10 to 60000 milliseconds. This setting must be smaller than the maximum interval.

Usage guidelines

The LSP generation timer sets the delay for ISIS-SPB to generate a new version of an LSP in response to an LSP change. For example, an update occurs because of a change in adjacency, interface metric value, system ID, or area address.

The LSP generation timer is an exponential generation timer. With this timer, ISIS-SPB quickly responds to the first events for an LSP and then slows down to protect the CPU from frequent LSP generation.

When the network is stable, the LSP generation timer is set to the minimum interval for each LSP generation. When the network is unstable, the LSP generation timer increments by incremental-interval×2

n-2

(n is the number of generation times) for each LSP generation until the maximum interval is reached. If an event triggers LSP generation after the maximum interval is reached, the LSP generation timer re-initiates with the minimum interval.

NOTE:

The network is considered unstable if the interval between consecutive LSP generation events is smaller than two times the maximum interval.

Examples

# Set the maximum LSP generation interval, the minimum LSP generation interval, and the base number for the incremental interval to 10 seconds, 100 milliseconds, 200 milliseconds, respectively.

Parameters

seconds: Specifies the maximum LSP lifetime in the range of 1 to 65535 seconds.

Usage guidelines

This command specifies the maximum amount of time for an LSP generated by the device to be retained in an LSDB.

SPBM nodes add a lifetime in each LSP they have advertised. If an SPBM node does not receive an update for an LSP before its lifetime expires, the SPBM node performs the following actions:

• Removes the LSP from the LSDB.

• Retains the LSP digest for 60 seconds.

• Floods an update of the LSP with a lifetime of 0. The SPBM neighbors remove the LSP from their

LSDBs when they receive the LSP update.

To prevent unnecessary LSP age-outs, increase the LSP lifetime on a slow network.

Examples

# Set the maximum LSP lifetime to 1500 seconds.

Page 79

Parameters

seconds: Specifies the LSP refresh interval in the range of 1 to 65534 seconds.

Usage guidelines

To prevent LSPs from age-out and synchronize LSDBs, ISIS-SPB performs periodic LSP update. The LSP refresh interval sets the interval at which ISIS-SPB regularly regenerates an LSP, regardless of whether any change has occurred to the LSP.

A short refresh interval improves network convergence time, but it also uses more bandwidth resources and system resources.

To avoid unnecessary LSP age-outs, make sure the LSP refresh interval is shorter than the LSP lifetime.

incremental-interval: Specifies the base number for the incremental interval, in the range of 10 to 60000 milliseconds. This setting must be smaller than the maximum interval.

Page 80

Usage guidelines

The SPF calculation timer sets the delay between consecutive SPF calculations. You can increase the timer for ISIS-SPB to react quickly to topology changes, and decrease the timer to protect the CPU from frequent SPF calculations.

The SPF timer is an exponential generation timer. With this timer, ISIS-SPB quickly responds to the first events that trigger SPF calculation and then slows down to protect the CPU from frequent SPF calculations.

When the network is stable, the SPF calculation timer is set to the minimum interval for each SPF computation. When the network is unstable, the SPF calculation timer increments by incremental-interval×2

n-2

(n is the number of calculations) for each SPF calculation until the maximum interval is reached. If an event triggers SPF calculation after the maximum interval is reached, the SPF calculation timer re-initiates with the minimum interval.

NOTE:

The network is considered unstable if the interval between consecutive SPF calculations is smaller than two times the maximum interval.

Parameters

vsi-name: Specifies the name of a VSI, a case-sensitive string of 1 to 31 characters.

access-mode: Specifies the access mode. By default, the access mode is VLAN.

ethernet: Specifies the Ethernet access mode.

vlan: Specifies the VLAN access mode.

Usage guidelines

After you bind a Layer 3 interface to a VSI, packets received from the interface are forwarded according to the MAC address table of the VSI. After you bind a service instance on a Layer 2 interface to a VSI, packets received from the interface and matching the service instance are forwarded according to the MAC address table of the VSI.

The access mode determines how a BEB considers the VLAN tag in Ethernet frames received from a CE and how the BEB forwards Ethernet frames to the CE.

• VLAN access mode—Ethernet frames received from the CE must carry a VLAN tag in the Ethernet

header. The BEB considers the VLAN tag as a P-tag assigned by the service provider. Ethernet frames sent to the CE must also carry the P-tag.

• Ethernet access mode—If Ethernet frames from the CE have a VLAN tag in the header, the PE

considers it as a U-tag and ignores it. Ethernet frames sent to the CE do not carry the P-tag.

Before you configure this command for a service instance, make sure you have configured match criteria for the service instance by using the encapsulation command.

Examples

# Configure service instance 200 on Layer 2 interface FortyGigE 1/0/1 to match packets with an outer VLAN tag of 200, and bind the service instance to the VSI vpn1.
