By default, no LSR ID is set.

Usage Guidelines
Usage Scenario
An LSR ID uniquely identifies an LSR on an MPLS network. MPLS can be globally enabled only after an LSR ID is set for a device.
No default LSR ID is provided, and the LSR ID needs to be configured. As a network-wide unique 32-bit host address is assigned to a loopback interface, using this interface as an LSR ID is recommended.
Follow-up Procedure
Run the mpls command to globally enable MPLS.
Precautions
To change or deleted an existing LSR ID, run the undo mpls command in the system view first to delete all MPLS configurations.
NOTICE:
NOTICE: Running the undo mpls command deletes
all MPLS configurations (including established LDP sessions and LSPs).
