Basic MPLS commands
display mpls forwarding ilm
Use display mpls forwarding ilm to display Incoming Label Map (ILM) entries.
Syntax
display mpls forwarding ilm [ label ] [ slot slot-number ]
Views
Any view
Predefined user roles
network-admin
network-operator
Parameters
label: Displays the ILM entry with the specified incoming label. The value range for this argument
is 16 to 250000. If you do not specify an incoming label, this command displays ILM entry information
for all incoming labels.
slot slot-number: Specifies a card by its slot number. If you do not specify a card, this
command displays ILM entries on the active MPU.
Usage guidelines
An ILM entry records the label operation type, outgoing label, and other forwarding information.
After an LSR receives a labeled packet, it performs the following operations:
1. Identifies the ILM entry that matches the top label of the packet.
2. Performs the specified label operation.
3. Forwards the packet.
Examples
# Display all ILM entries.
<Sysname> display mpls forwarding ilm
Total ILM entries: 3
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

Parameters
nid: Displays the NHLFE entry with the specified NID. The NID value range is 0 to 4294967294. If
you do not specify an NID, this command displays NHLFE entry information for all NIDs
slot slot-number: Specifies a card by its slot number. If you do not specify a card, this
command displays NHLFE entries on the active MPU.
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 performs the following operations:
3
1. Obtains the bottom label and NID in the matching FIB or ILM entry.
2. Obtains the outer label in the NHLFE entry identified by the NID.
Examples
# Display the NHLFE entry with NID 2048.
