mpls te timer fast-reroute

Function

The mpls te timer fast-reroute command sets the interval at which the binding between a bypass CR-LSP and a primary CR-LSP is refreshed.

The undo mpls te timer fast-reroute command restores the default configuration.

By default, the time weight used to calculate the interval is 300. And the actual interval at which the binding between a bypass CR-LSP and a primary LSP is refreshed depends on device performance and the maximum number of LSPs that can be established on the device.

Format

Usage Guidelines

Usage Scenario

After TE FRR is configured, a PLR refreshes the binding between a bypass CR-LSP and a primary CR-LSP at a specified interval. The PLR searches for the optimal bypass CR-LSP and binds it to a primary CR-LSP. To set the interval at which the binding between a bypass CR-LSP and a primary CR-LSP is refreshed, run the mpls te timer fast-reroute command.

The PLR calculates the interval using the value of weight. And the actual interval depends on device performance and the maximum number of LSPs that can be established on the device

Prerequisites

RSVP-TE has been enabled by running the mpls rsvp-te command in the MPLS view.

Example

# Set the weight of the interval at which binding between a bypass CR-LSP and a primary LSP is refreshed to 120.
