domain.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
mpls lsr-id lsr-id
An LSR ID is set for the local LSR.
Note the following when configuring an LSR ID:
l LSR IDs must be set before other MPLS commands are run.
l No default LSR ID is provided and the LSR ID needs to be configured.
l Using the IP address of a loopback interface as the LSR ID is recommended for an LSR.
l Before a configured LSR ID is changed, the undo mpls command must be run in the system
Step 3 Run:
mpls
MPLS is enabled globally and the MPLS view is displayed.
