2.8.2 Enabling LDP Auto FRR

To configure LDP Auto FRR, you need to configure the ingress or transit node.
Procedure
Step 1 Run:
system-view
The system view is displayed.
Step 2 Run:
mpls ldp
The MPLS LDP view is displayed.
Step 3 Run:
auto-frr lsp-trigger { all | host | ip-prefix ip-prefix-name | none }
The policy for triggering LDP to set up backup LSPs is configured.
By default, the backup routes with 32-bit addresses trigger LDP to setup backup LSPs.
The auto-frr lsp-trigger command is restricted by the lsp-trigger command. If both the auto-
frr lsp-trigger command and the lsp-trigger command are configured, the established backup
LSPs satisfy both the policy for triggering the setup of LSPs by LDP and the policy for triggering
the setup of backup LSPs by LDP.
