Configuring the RSVP Signaling Delay-Trigger Function

Context

In the case that a fault occurs on an MPLS network, a great number of RSVP CR-LSPs need to be reestablished. This causes consumption of a large number of system resources. By configuring the delay for triggering the RSVP signaling, you can reduce the consumption of system resources when establishing an RSVP CR-LSP.

Perform the following configurations on each node on which multiple CR-LSPs need to be reestablished.

Procedure

Run system-view
The system view is displayed.
Run mpls
The MPLS view is displayed.
Run mpls te signaling-delay-trigger enable
The RSVP signaling delay-trigger function is enabled.

By default, the RSVP signaling delay-trigger function is not enabled.
