Basic IP routing commands

The term "router" in this chapter refers to both routers and Layer 3 switches.

The term "interface" in the routing features collectively refers to Layer 3 interfaces, including VLAN interfaces and Layer 3 Ethernet interfaces. You can set an Ethernet port as a Layer 3 interface by

using the port link-mode route command (see Layer 2—LAN Switching Configuration Guide).

HPE FlexNetwork 3600 v2 SI Switch Series does not support OSPF, BGP, IS-IS, OSPFv3, IPv6 BGP, or IPv6 IS-IS.

display ip routing-table

Syntax

display ip routing-table [ vpn-instance vpn-instance-name ] [ verbose ] [ | { begin | exclude | include } regular-expression ]

View

Any view

Default level

1: Monitor level

Parameters

vpn-instance vpn-instance-name: Specifies an MPLS L3VPN. vpn-instance-name is a

case-sensitive string of 1 to 31 characters. If no VPN is specified, the information of the public network is displayed.

verbose: Displays detailed routing table information, including inactive routes. Without this keyword, the command displays only brief information about active routes.

|: Filters command output by specifying a regular expression. For more information about regular expressions, see Fundamentals Configuration Guide.

begin: Displays the first line that matches the specified regular expression and all lines that follow. exclude: Displays all lines that do not match the specified regular expression. include: Displays all lines that match the specified regular expression.

regular-expression: Specifies a regular expression, a case-sensitive string of 1 to 256 characters.

Description

Use display ip routing-table to display brief information about active routes in the routing table.

This command displays brief information about a routing table, with a routing entry contained in one line. The information displayed includes destination IP address/mask length, protocol, priority, cost, next hop, and outbound interface. This command displays only the optimal routes in use.

Use display ip routing-table verbose to display detailed information about all routes in the routing table.

This command displays detailed information about all active and inactive routes, including the statistics of the entire routing table and information for each route.

Examples

# Display brief information about active routes in the routing table.

Field Description

Route status:

• Active—This is an active unicast route.

• Adv—This route can be advertised.

• Delete—This route is deleted.

• Gateway—This is an indirect route.

• Holddown—Number of holddown routes. Holddown is a route advertisement

policy used in some distance vector (D-V) routing protocols, such as RIP, to avoid the propagation of some incorrect routes. It distributes a Holddown route during a period regardless of whether a new route to the same destination is found. For more information, refer to relevant routing protocols.

• Int—The route was discovered by an Interior Gateway Protocol (IGP).

• NoAdv—The route is not advertised when the router advertises routes based on

policies.

State

• NotInstall—Among routes to a destination, the route with the highest priority is

installed into the core routing table and advertised. A NotInstall route cannot be installed into the core routing table but can be advertised.

• Reject—The packets matching a Reject route will be dropped. Besides, the

router sends ICMP unreachable messages to the sources of the dropped packets. The Reject routes are usually used for network testing.

• Static—A static route is not lost when you perform the save operation and then restart the router. Routes configured manually are marked as static.

• Unicast—Unicast routes.

• Inactive—Inactive routes.

• Invalid—Invalid routes.

• WaitQ—The route is the WaitQ during route recursion.

• TunE—Tunnel.

• GotQ—The route is in the GotQ during route recursion.

Age

Tag Route tag.

Time for which the route has been in the routing table, in the sequence of hour, minute, and second from left to right.

• display ip routing-table ip-address mask:

• display ip routing-table ip-address longer-match:

• display ip routing-table ip-address mask longer-match:

{ The system ANDs the input destination IP address with the subnet mask in each route entry. { The system ANDs the destination IP address in each route entry with its own subnet mask.

If the two operations yield the same result for an entry and this entry is active, it is displayed.

{ The system ANDs the input destination IP address with the input subnet mask. { The system ANDs the destination IP address in each route entry with the input subnet

mask.

If the two operations yield the same result for an entry and the entry is active with a subnet mask less than or equal to the input subnet mask, the entry is displayed.

Only route entries that exactly match the input destination address and mask are displayed.

{ The system ANDs the input destination IP address with the subnet mask in each route entry. { The system ANDs the destination IP address in each route entry with its own subnet mask.

If the two operations yield the same result for multiple entries that are active, the one with the longest mask length is displayed.

{ The system ANDs the input destination IP address with the input subnet mask. { The system ANDs the destination IP address in each route entry with the input subnet

mask.

If the two operations yield the same result for multiple entries with a mask less than or equal to the input subnet mask, the one that is active with longest mask length is displayed.

Use display ip routing-table ip-address1 { mask-length | mask } ip-address2 { mask-length | mask }

to display route entries with destination addresses within a specified range.

Description

Use display ipv6 routing-table ipv6-address to display routing information about the specified

destination IPv6 address.

Executing the command with different parameters yields different output:

• display ipv6 routing-table ipv6-address prefix-length:

• display ipv6 routing-table ipv6-address prefix-length longer-match:

{ The system ANDs the input destination IPv6 address with the input prefix length. { The system ANDs the destination IPv6 address in each route entry with the input prefix

length.

If the two operations yield the same result for an entry and the entry is active with a prefix length less than or equal to the input prefix length, the entry is displayed.

{ Only route entries that exactly match the input destination address and prefix length are

displayed.

{ The system ANDs the input destination IPv6 address with the input prefix length. { The system ANDs the destination IPv6 address in each route entry with the input prefix

length.

If the two operations yield the same result for multiple entries with a prefix length less than or equal to the input prefix length, the one that is active with the longest prefix length is displayed.

Use display ipv6 routing-table ipv6-address1 ipv6-address2 to display routes whose destinations

fall into the specified IPv6 address range.

Parameters

vpn-instance s-vpn-instance-name&<1-6>: Specifies a source MPLS L3VPN. s-vpn-instance-name

is a case-sensitive string of 1 to 31 characters. &<1-6> indicates the argument before it can be entered up to 6 times. Each VPN has its own routing table, and the configured static route is installed in the routing tables of the specified VPNs.

dest-address: Specifies the destination IP address of the static route, in dotted decimal notation. mask: Specifies the mask of the IP address, in dotted decimal notation. mask-length: Specifies the mask length, in the range of 0 to 32. next-hop-address: Specifies the IP address of the next hop, in dotted decimal notation. interface-type interface-number: Specifies the output interface by its type and number. If the output

interface is a broadcast interface, such as an Ethernet interface or a VLAN interface, the next hop address must be specified.

vpn-instance d-vpn-instance-name: Specifies a destination MPLS L3VPN. d-vpn-instance-name is

a case-sensitive string of 1 to 31 characters. If a destination VPN is specified, the router will search

the output interface in the destination VPN based on the configured next-hop-address. next-hop-address public: Indicates that the specified next-hop-address is a public network address,

rather than a VPN instance address.

preference preference-value : Specifies the preference of the static route, in the range of 1 to 255

and defaults to 60.

tag tag-value: Sets a tag value for the static route from 1 to 4294967295. The default is 0. Tags of

routes are used in routing policies to control routing. For more information about routing policies, see "Routing policy configuration commands."

permanent: Specifies the route as a permanent static route. If the output interface is down, the permanent static route is still active.

description description-text: Configures a description for the static route, which consists of 1 to 60

characters, including special characters like space, but excluding question marks (?). bfd: Enable the bidirectional forwarding detection (BFD) function to detect reachability of the static

route's next hop. Once the next hop is unreachable, the system will switch to a backup route.

control-packet: Implements BFD in the control mode. echo-packet: Implements BFD in the echo mode. bfd-source ip-address: Specifies the source address of BFD packets. Hewlett Packard Enterprise

recommends you configure loopback interface address.

track track-entry-number: Associates the static route with a track entry. Use the track-entry-number argument to specify a track entry number, in the range of 1 to 1024.

Description

Use ip route-static to configure a unicast static route.

Page 38

Use undo ip route-static to delete a unicast static route.

When you configure a unicast static route, follow these guidelines:

• If the destination IP address and the mask are both 0.0.0.0 (or 0), the configured route is a

default route. The default route will be used for forwarding a packet if no route is available for the packet in the routing table.

• Implement different routing policies by tuning route preference. For example, to enable multiple

routes to the same destination address to share load, assign the same preference to the routes; to enable them to back up one another, assign different preferences to them.

• Specify the output interface or the next hop address of the static route as needed.

{ If the output interface supports network address-to-link layer address resolution or is a

point-to-point interface, you may specify only the interface or the next hop address.

{ If the output interface is a Null 0 interface, no next hop address is required. { If you specify a broadcast interface (such as an Ethernet interface or a VLAN interface) as

the output interface for a static route, you must specify the corresponding next hop of the interface at the same time.

{ To implement BFD with the control-packet mode, the remote end must create a BFD

session; otherwise the BFD function cannot work. To implement BFD with the echo-packet mode, the BFD function can work without the remote end needing to create any BFD session.

{ To configure a static route and enable BFD control packet mode for it, specify an output

interface and a direct next hop—BFD establishes a direct session, or specify an indirect next hop and a specific BFD packet source address—BFD establishes an indirect session—for the static route.

• The next hop address cannot be the IP address of a local interface (such as an Ethernet

interface and VLAN interface). Otherwise, the static route does not take effect.

• Enabling BFD for a flapping route could worsen the situation. Therefore, use it with caution. For

more information about BFD, see High Availability Configuration Guide.

• If the track module uses NQA to detect the reachability of the private network static route's next

hop, the VPN instance number of the static route's next hop must be identical to that configured in the NQA test group.

• If a static route needs route recursion, the associated track entry must monitor the next hop of

the recursive route instead of that of the static route. Otherwise, a valid route may be mistakenly considered invalid.

• Do not specify the permanent keyword together with the bfd or track keyword. Related commands: display ip routing-table and ip route-static default-preference.

Parameters

acl-number: Number of an ACL used to filter outbound routes, in the range of 2000 to 3999.

ip-prefix ip-prefix-name: Name of an IP prefix list used to filter outbound routes, a string of 1 to 19

characters.

protocol: Filters outbound routes redistributed from a specified routing protocol, which can be bgp, direct, isis, ospf, rip, and static.

process-id: Process ID of the specified routing protocol, in the range of 1 to 65535. You need to specify a process ID when the routing protocol is rip, ospf, or isis.

interface-type interface-number: Specifies an interface by its type and number.

Description

Use filter-policy export to configure the filtering of RIP outgoing routes. Only routes not filtered out can be advertised.

Use undo filter-policy export to remove the filtering.

Page 51

By default, RIP does not filter outbound routes.

If a protocol is specified, RIP filters only the routes redistributed from the specified routing protocol.

Otherwise, RIP filters all routes to be advertised.

If interface-type interface-number is specified, RIP filters only the routes advertised by the specified

interface. Otherwise, RIP filters routes advertised by all RIP interfaces.

If you want to reference an advanced ACL (with a number from 3000 to 3999) in the command, the

ACL should be configured with the rule [ rule-id ] { deny | permit } ip source sour-addr sour -wildcard command to deny/permit a route with the specified destination, or with the rule [ rule-id ] { deny | permit } ip source sour-addr sour-wildcard destination dest-addr dest-wildcard command to deny/permit a route with the specified destination and mask. The source keyword specifies the destination address of a route and the destination keyword specifies the subnet mask of the route

(the subnet mask must be valid; otherwise, the configuration is ineffective).

RIP view

Default level

2: System level

Parameters

None

Description

Use host-route to enable host route reception. Use undo host-route to disable host route reception.

By default, receiving host routes is enabled.

In some cases, a router may receive many host routes from the same network segment. These routes are not helpful for routing and occupy a large amount of network resources. Use undo host-route to disable receiving of host routes.

RIPv2 can be disabled from receiving host routes, but RIPv1 cannot.

Default level

2: System level

Parameters

protocol: Specifies a routing protocol from which to redistribute routes. It can be bgp, direct, isis, ospf, rip, or static.

process-id: Process ID, in the range of 1 to 65535. The default is 1. It is available only when the protocol is isis, rip, or ospf.

all-processes: Enables route redistribution from all the processes of a protocol. This keyword takes effect only when the protocol is rip, ospf, or isis.

allow-ibgp: When the protocol argument is set to bgp, allow-ibgp is an optional keyword. cost: Cost for redistributed routes, in the range of 0 to 16. If cost is not specified, the default cost

specified by the default cost command applies. tag: Tag marking redistributed routes, in the range of 0 to 65,535. The default is 0.

Page 54

route-policy route-policy-name: Specifies a routing policy with 1 to 63 case-sensitive characters.

Description

Use import-route to enable route redistribution from another routing protocol. Use undo import-route to disable route redistribution.

By default, RIP does not redistribute routes from other routing protocols. The import-route bgp command only redistributes eBGP routes. The import-route bgp

allow-ibgp command additionally redistributes IBGP routes, which may cause routing loops. Only active routes can be redistributed. Use the display ip routing-table protocol command to

display route state information.

The undo import-route protocol all-processes command cancels the configuration made by the import-route protocol all-processes command, rather than the import-route protocol process-id

command. Related commands: default cost.

Examples

# Redistribute static routes, and set the cost to 4.

<Sysname> system-view [Sysname] rip 1 [Sysname-rip-1] import-route static cost 4

# Configure the default cost for redistributed routes as 3.

View

RIP view

Default level

2: System level

Parameters

network-address: IP address of a network segment, which can be the IP network address of any

interface.

Description

Use network to enable RIP on the interface attached to the specified network. Use undo network to disable RIP on the interface attached to the specified network.

RIP is disabled on an interface by default.

RIP runs only on the interfaces attached to the specified network. For an interface not on the specified network, RIP neither receives/sends routes on it nor forwards interface route through it. You need to specify the network after enabling RIP to validate RIP on a specific interface.

For a single process, the network 0.0.0.0 command can enable RIP on all interfaces, but the command is not applicable in case of multi-process.

If a physical interface is attached to multiple networks, you cannot advertise these networks in different RIP processes.

Examples

# Enable RIP on the interface attached to the network 129.102.0.0.

Use undo peer to remove the IP address of a neighbor.

By default, no neighbor is specified.

You need not use the peer ip-address command when the neighbor is directly connected; otherwise

the neighbor may receive both the unicast and multicast (or broadcast) of the same routing information.

Examples

By default, no RIP process runs.

You must create a VPN instance before you apply a RIP process to it. For related configuration, see

the ip vpn-instance command in the MCE Command Reference.

You must enable the RIP process before configuring the global parameters. This limitation is not for configuration of interface parameters.

The configured interface parameters become invalid after you disable the RIP process.

Default level

2: System level

Parameters

md5: Specifies the MD5 authentication mode. rfc2082: Uses the message format defined in RFC 2082. cipher: Sets a ciphertext authentication key or password. If this keyword is not specified, you set a

plaintext authentication key or password.

key-string: Specifies the MD5 key string. This argument is case sensitive. It must be a plaintext string

of 1 to 16 characters, or a ciphertext string of 33 to 53 characters.

key-id: Specifies the MD5 key number, in the range of 1 to 255.

rfc2453: Uses the message format defined in RFC 2453 (IETF standard). simple: Specifies the simple authentication mode.

password: Sets the password in simple authentication mode. This argument is case sensitive. It

must be a plaintext string of 1 to 16 characters, or a ciphertext string of 33 to 53 characters.

Description

Use rip authentication-mode to configure RIPv2 authentication mode and parameters. Use undo rip authentication-mode to cancel authentication.

The key string you configured can overwrite the old one, if any.

The authentication key or password, set in either plain text or cipher text, is saved to the configuration file in cipher text.

This feature does not apply to RIPv1 because RIPv1 does not support authentication. Although you can specify an authentication mode for RIPv1 in interface view, the configuration does not take effect.

View

Interface view

Default level

2: System level

Parameters

1: RIP version 1. 2: RIP version 2. broadcast: Sends RIPv2 messages in broadcast mode. multicast: Sends RIPv2 messages in multicast mode.

Description

Use rip version to specify a RIP version for the interface. Use undo rip version to remove the specified RIP version.

By default, no RIP version is configured for an interface, which uses the global RIP version. If the global RIP version is not configured, the interface can only send RIPv1 broadcasts and can receive RIPv1 broadcasts and unicasts, and RIPv2 broadcasts, multicasts, and unicasts.

If RIPv2 is specified with no sending mode configured, RIPv2 messages will be sent in multicast mode.

When RIPv1 runs on an interface, the interface can perform the following operations:

• Sends RIPv1 broadcast messages

• Receives RIPv1 broadcast and unicast messages

When RIPv2 runs on the interface in broadcast mode, the interface can perform the following operations:

Page 67

• Sends RIPv2 broadcast messages

• Receives RIPv1 broadcast and unicast messages, and RIPv2 broadcast, multicast, and unicast

messages

When RIPv2 runs on the interface in multicast mode, the interface can perform the following operations:

• Sends RIPv2 multicast messages

• Receives RIPv2 broadcast, multicast, and unicast messages

Parameters

None

Description

Use summary to enable automatic RIPv2 summarization. Natural masks are used to advertise summary routes so as to reduce the size of routing tables.

Use undo summary to disable automatic RIPv2 summarization so that all subnet routes can be broadcast.

By default, automatic RIPv2 summarization is enabled.

Enabling automatic RIPv2 summarization can reduce the size of the routing table to enhance the scalability and efficiency of large networks.

RIP view

Default level

2: System level

Parameters

garbage-collect-value: Garbage-collect timer time in seconds, in the range of 1 to 3600. suppress-value: Suppress timer time in seconds, in the range of 0 to 3600. timeout-value: Timeout timer time in seconds, in the range of 1 to 3600. update-value: Update timer time in seconds, in the range of 1 to 3600.

Description

Use timers to configure RIP timers. By adjusting RIP timers, you can improve network performance. Use undo timers to restore the default.

By default, the garbage-collect timer is 120 seconds, the suppress timer is 120 seconds, the timeout timer is 180 seconds, and the update timer is 30 seconds.

RIP is controlled by the following timers:

Page 69

• Update timer—Defines the interval between routing updates.

• Timeout timer—Defines the route aging time. If no routing update related to a route is received

• Suppress timer—Defines how long a RIP route stays in suppressed state. When the metric of

• Garbage-collect timer—Defines the interval from when the metric of a route becomes 16 to

IMPORTANT:

• Hewlett Packard Enterprise does not recommend changing the default values of these timers.

• The time lengths of these timers must be kept consistent on all routers in the network.

Examples

# Specifies the update, timeout, suppress, and garbage-collect timers as 5, 15, 15 and 30.

<Sysname> system-view [Sysname] rip 100 [Sysname-rip-100] timers update 5 timeout 15 suppress 15 garbage-collect 30

after the aging time, the metric of the route is set to 16 in the routing table.

a route is 16, the route enters the suppressed state. In suppressed state, only routes which come from the same neighbor and whose metric is less than 16 will be received by the router to replace unreachable routes.

when it is deleted from the routing table. During the Garbage-Collect timer length, RIP advertises the route with the routing metric set to 16. If no routing update is announced for that route after the Garbage-Collect timer expires, the route will be deleted from the routing table.

Default level

2: System level

Parameters

1: Specifies the RIP version as RIPv1. 2: Specifies the RIP version as RIPv2. RIPv2 messages are multicast.

Description

Use version to specify a global RIP version. Use undo version to remove the configured global RIP version.

By default, if an interface has a RIP version specified, the RIP version takes effect; if it has no RIP version specified, it can send RIPv1 broadcasts, and receive RIPv1 broadcasts and unicasts, and RIPv2 broadcasts, multicasts, and unicasts.

If an interface has an RIP version specified, the RIP version takes precedence over the global RIP version.

If no RIP version is specified for the interface and the global version is RIPv1, the interface inherits RIPv1, and it can send RIPv1 broadcasts, and receive RIPv1 broadcasts and unicasts.

If no RIP version is specified for the interface and the global version is RIPv2, the interface operates in the RIPv2 multicast mode, and it can send RIPv2 multicasts, and receive RIPv2 broadcasts, multicasts, and unicasts.

Examples

# Specify RIPv2 as the global RIP version.

Default level

2: System level

Parameters

ip-address: IP address of the summary route in dotted decimal notation. mask: Summary route mask, in dotted decimal notation. mask-length: Length of summary route mask, in the range of 0 to 32 bits.

cost cost: Specifies the cost of the summary route, in the range of 1 to 16777214. For Type-1

external routes, the cost defaults to the largest cost among routes that are summarized. For Type-2 external routes, the cost defaults to the largest cost among routes that are summarized plus 1.

not-advertise: Disables advertising the summary route. If the keyword is not specified, the route is advertised.

Page 73

tag tag: Specifies a tag value for the summary route, used by a routing policy to control summary

route advertisement, in the range of 0 to 4294967295. The default is 1.

Description

Use asbr-summary to configure a summary route. Use undo asbr-summary to remove a summary route.

No ASBR route summarization is configured by default. With the asbr-summary command configured, an ASBR summarizes redistributed routes that fall

into the specified address range into a single route. If the ASBR resides in an NSSA area, it advertises the summary route in a Type-7 LSA into the area.

With the asbr-summary command configured, an NSSA ABR summarizes routes described by Type-5 LSAs translated from Type-7 LSAs into a single route and advertises the summary route to other areas. This command does not take effect on non NSSA ABRs.

If the undo asbr-summary command is used, summarized routes will be advertised. Related command: display ospf asbr-summary.

Examples

# Summarize redistributed static routes into a single route, and specify a tag value of 2 and a cost of 100 for the summary route.

default-route-advertise (OSPF view)

Syntax

undo default-route-advertise

View

OSPF view

Default level

2: System level

Parameters

always: Generates a default route in a Type-5 LSA into the OSPF routing domain regardless of

whether there is a default route in the routing table. If this keyword is not specified, the router generates a default route in a Type-5 LSA into the OSPF routing domain only when an active default route that does not belong to the current OSPF process exists in the IP routing table.

permit-calculate-other: Calculates default routes from other routers with this keyword specified or does not calculate default routes from other routers without this keyword specified when the router generates a default route in a Type-5 LSA into the OSPF routing domain. If the router generates no default route in a Type-5 LSA into the OSPF routing domain, the router calculates default routes from other routers regardless of whether this keyword is specified.

cost cost: Specifies a cost for the default route, in the range of 0 to 16777214. If no cost is specified, the default cost specified by the default cost command applies.

route-policy route-policy-name: Specifies a routing policy name, a string of 1 to 63 case-sensitive

characters. When a default route exists in the routing table and the specified routing policy is matched, the command distributes a default route in a Type-5 LSA into the OSPF routing domain, and the routing policy modifies some values in the Type-5 LSA. If the always keyword is specified at the same time, the command can distribute a default route in a Type-5 LSA into the OSPF routing domain when the specified routing policy is matched, regardless of whether a default route exists in the routing table, and the routing policy modifies some values in the Type-5 LSA.

type type: Specifies a type for the Type-5 LSA: 1 or 2. If type is not specified, the default type for the Type-5 LSA specified by the default type command applies.

summary: Advertises the Type-3 summary LSA of the specified default route.

Description

Use default-route-advertise to generate a default route into the OSPF routing domain. Use undo default-route-advertise to disable OSPF from distributing a default external route.

By default, no default route is distributed. The default-route-advertise summary cost command is applicable only to VPNs, and the default

route is redistributed in a Type-3 LSA. The PE router advertises the redistributed default route to the CE router.

Using the import-route command cannot redistribute a default route. To redistribute a default route, use the default-route-advertise command.

If neither the always nor permit-calculate-other keyword is specified, the router generates a default route in a Type-5 LSA into the OSPF routing domain only when an active default route that does not belong to the current OSPF process exists in the IP routing table. The router then does not calculate default routes from other routers.

Related commands: import-route and default.
