Usage Guidelines

Usage Scenario

If a fault occurs on an MPLS network and a large number of RSVP CR-LSPs need to be re-established, a large amount of system resources may be required. In this case, after the RSVP signaling delay-trigger function is configured, the interval between re-establishments of a CR-LSP is prolonged so that system resources are saved.

Prerequisites

Before running the mpls te signaling-delay-trigger enable command, the mpls te command must be run in the MPLS view.

Precautions

Use caution when configuring the RSVP signaling delay-trigger function because it causes the delay of CR-LSP convergence. The default settings are recommended.

Example
