Usage Guidelines

Usage Scenario

By default, the LSR ID of an LDP instance is the same as the MPLS LSR ID configured using the mpls lsr-id command. On some networks such as the BGP/MPLS VPNs to which VPN instances apply, if the VPN address space and the public network address space overlap, configure LSR IDs for LDP instances to ensure the correct establishment of TCP connections.

Prerequisites

MPLS has been enabled globally using the mpls (system view) command.
MPLS LDP has been enabled globally using the mpls ldp (system view) command.

Precautions

Modifying or deleting the LSR ID of an LDP instance causes the reestablishment of all sessions in the LDP instance.

Example

# Set the LSR ID of an LDP instance to 10.1.1.1.

<HUAWEI> system-view
[HUAWEI] mpls
[HUAWEI-mpls] quit
[HUAWEI] mpls ldp
[HUAWEI-mpls-ldp] lsr-id 10.1.1.1
Warning: All the related sessions will be deleted if the operation is performed!Continue? (y/n)y
