Basic MPLS commands
The switch operates in IRF or standalone (the default) mode. For more information about IRF, see
IRF Configuration Guide.
display mpls forwarding ilm
Use display mpls forwarding ilm to display Incoming Label Map (ILM) entries.
Syntax
In standalone mode:
display mpls forwarding ilm [ label ] slot slot-number
In IRF mode:
display mpls forwarding ilm [ label ] chassis chassis-number slot slot-number
Views
Any view
Predefined user roles
network-admin
network-operator
mdc-admin
mdc-operator
Parameters
label: Displays the ILM entry with the specified incoming label. The value range for the incoming
label is 16 to 1000000. If you do not specify an incoming label, the command displays information
about all ILM entries on the specified card.
slot slot-number: Specifies a card by its slot number. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The
chassis-number argument specifies the ID of the IRF member device, and the slot-number argument
specifies the number of the slot that holds the card. (In IRF mode.)
Usage guidelines
An ILM entry records the label operation type, outgoing label, and other forwarding information.
After an LSR receives a labeled packet, it identifies the ILM entry that matches the top label of the
packet, performs the specified label operation, and forwards the packet.
Examples
# Display the ILM entry with incoming label 30.
<Sysname> display mpls forwarding ilm 30
Flags: T - Forwarded through a tunnel
N - Forwarded through the outgoing interface to the nexthop IP address
B - Backup forwarding information
A - Active forwarding information

slot slot-number: Specifies a card by its slot number. (In standalone mode.)
chassis chassis-number slot slot-number: Specifies a card on an IRF member device. The
chassis-number argument specifies the ID of the IRF member device, and the slot-number argument
specifies the number of the slot that holds the card. (In IRF mode.)
Usage guidelines
An NHLFE entry records label forwarding information, such as the outgoing label and outgoing
interface. NHLFE entries are mainly used to add multiple labels to packets. To add multiple labels to
a packet, an LSR first obtains the bottom label and NID in the matching FIB or ILM entry, and then
obtains the outer label in the NHLFE entry identified by the NID.
Examples
# Display the NHLFE entry with NID 2048.

Predefined user roles
network-admin
mdc-admin
Parameters
explicit-null: Specifies the egress to advertise an explicit null label of 0 to the penultimate hop.
implicit-null: Specifies the egress to advertise an implicit null label of 3 to the penultimate hop.
Usage guidelines
If the penultimate hop supports PHP, HP recommends that you configure the egress to advertise an
implicit null label to the penultimate hop. If you want to simplify packet forwarding on the egress
but keep labels in packets for the egress to determine QoS policies, you can configure the egress to
advertise an explicit null label to the penultimate hop.
As a penultimate hop, the device allows the egress to advertise to the penultimate hop an implicit
null label or an explicit null label.
The mpls label advertise command takes effect only for the LSPs established after the command is
executed. To apply the new setting to LSPs established before the command is executed, delete and
then re-establish those LSPs:
• To re-establish LDP LSPs, execute the reset mpls ldp command to reset the LDP session.
16
• To re-establish BGP LSPs, delete the routes corresponding to the BGP LSPs, and then
redistribute the routes.

17
undo mpls mtu
Default
The MPLS MTU of an interface is not configured. Fragmentation for MPLS packets is based on the
MTU of the interface, and the length of a fragment does not include that of the MPLS label. Thus,
after an MPLS label is inserted into a fragment, the length of the MPLS fragment may exceed the
interface MTU.

18
Usage guidelines
The mpls ttl expiration enable command enables an LSR to generate an ICMP TTL-expired
message upon receiving an MPLS packet with TTL being 1. If the MPLS packet has only one label,
the LSR sends the ICMP TTL-expired message back to the source through IP routing. If the MPLS
packet has multiple labels, the LSR forwards the ICMP TTL-expired message along the LSP of the
MPLS packet to the egress, which then sends the message back to the source.
Examples
# Disable the MPLS TTL-expired messages sending function.
<Sysname> system-view
[Sysname] undo mpls ttl expiration enable
mpls ttl propagate
Use mpls ttl propagate to enable TTL propagation.
Use undo mpls ttl propagate to disable TTL propagation.
Syntax

undo mpls ttl propagate { public | vpn }
Default
TTL propagation is enabled for public network packets and disabled for VPN packets.
Views
System view
Predefined user roles
network-admin
mdc-admin
Parameters
public: Specifies public network packets.
vpn: Specifies VPN packets.
Usage guidelines
When TTL propagation is enabled, MPLS copies the IP TTL to the label TTL for packets entering the
MPLS network, and copies the label TTL to the IP TTL for packets leaving the MPLS network. If you
enable TTL propagation on both the ingress and egress, the IP tracert facility can show the real path
in the MPLS network.
When TTL propagation is disabled, MPLS sets the label TTL to 255 for packets entering the MPLS
network, and pops the label for packets leaving the MPLS network, without copying the label TTL
value to the IP TTL. The IP tracert facility cannot show the real path in the MPLS network.
Within an MPLS network, TTL is always copied between the labels of an MPLS packet. The mpls ttl
propagate command affects only the propagation between IP TTL and label TTL.
HP recommends setting the same TTL processing mode on all LSRs of an LSP.
To enable TTL propagation for a VPN, you must enable it on all PE devices in the VPN, so that you
can get the same traceroute result (hop count) from those PEs.

Parameters
lsp-name: Specifies a name for the static LSP, a case-sensitive string of 1 to 15 characters.
22
destination dest-addr: Specifies a destination IP address for the LSP.
mask: Specifies the mask of the destination IP address.
mask-length: Specifies the mask length of the destination address, in the range of 0 to 32.
nexthop next-hop-addr: Specifies a next hop address.
outgoing-interface interface-type interface-number: Specifies an outgoing interface by its type and
number. You can specify an outgoing interface only in a point-to-point network.
out-label out-label: Specifies an outgoing label, which can be 0, 3, or a value in the range of 16 to
1023.
Usage guidelines
The next hop or outgoing interface specified for the LSP must be consistent with the next hop or
outgoing interface of the optimal route destined for the specified address. If you configure a static
IP route for the LSP, be sure to specify the same next hop or outgoing interface for the static route
and the static LSP.
You must enable MPLS on the outgoing interface of the static LSP.
Examples
# Configure a static LSP on the ingress node: specify the LSP's name as bj-sh, destination address
as 202.25.38.1/24, next hop address as 202.55.25.33, and outgoing label as 237.

LDP commands
accept-label
Use accept-label to configure a label acceptance policy.
Use undo accept-label to remove the label acceptance policy.
Syntax
accept-label peer peer-lsr-id prefix-list prefix-list-name
undo accept-label peer peer-lsr-id
Default
No label acceptance policy is configured. LDP accepts all label mappings from all peers.

Parameters
peer peer-lsr-id: Specifies an LDP peer by its LSR ID.
prefix-list prefix-list-name: Specifies an IP prefix list by its name, a case-sensitive string of 1 to 63
characters.
Usage guidelines
Using the label acceptance policy, LDP accepts only the FEC-label mappings whose prefixes are
permitted by the specified IP prefix list from the specified peer.
This feature enables you to control the number of label mappings received from peers.
If you change the label acceptance policy to accept the previously denied label mappings from a
specific peer, for example, by using the undo accept-label command or by changing the IP prefix
list, you must execute the reset mpls ldp command to reset the LDP session with the specified peer
to apply the new policy.
Using a label advertisement policy on an LSR or using a label acceptance policy on its upstream LSR
can achieve the same purpose. HP recommends using the label advertisement policy to reduce
network load.
Examples
# Configure a label acceptance policy to accept only the FEC-label mappings containing prefixes
10.1.1.0/24 and 10.2.1.0/24 from the LDP peer 1.1.1.9.
<Sysname> system-view
[Sysname] ip prefix-list prefix-from-RTA index 1 permit 10.1.1.0 24
[Sysname] ip prefix-list prefix-from-RTA index 2 permit 10.2.1.0 24
