1546 CHAPTER 95: MPLS BASICS CONFIGURATION COMMANDS

By default, only loopback addresses with 32-bit masks can trigger LDP to establish

LSPs.

Note that:

■With the all keyword specified in the lsp-triggercommand, all static and IGP routes can trigger LDP to establish LSPs.

■Using ip-prefixprefix-namekeyword and argument combination in the lsp-triggercommand, only IGP routes surviving the IGP route filtering based on an IP address prefix list can trigger LDP to establish LSPs.

■For an LSP to be established, an exactly matched routing entry must exist on the LSR. With loopback addresses using 32-bit masks, only exactly matched host routing entries can trigger LDP to establish LSPs.

■An IP address prefix list affects only static routes and IGP routes.

■For information about IP address prefix list, refer to “IP Addressing Configuration Commands” on page 781.

Example # Specify LDP to allow all static and IGP routes to trigger LSP establishment.

lsr-id

Syntax lsr-idlsr-id

undo lsr-id

View MPLS LDP view/MPLS LDP VPN instance view

Parameter lsr-id: LDP LSR ID.

Description Use the lsr-idcommand to configure an LDP LSR ID.

Use the undo lsr-idcommand to remove a configured LDP LSR ID and all LDP sessions.

By default, the LDP LSR ID takes the value of the MPLS LSR ID.

Example # Configure the LDP LSR ID of the public network LDP.

[Sysname] mpls ldp

[Sysname-mpls-ldp] lsr-id 2.2.2.3

# Configure the LDP LSR ID of LDP instance named vpn1.
