(Optional) Configuring a TE FRR Scanning Timer

(Optional) Configuring a TE FRR Scanning Timer

Context

A TE FRR-enabled device periodically refreshes the binding between a bypass CR-LSP and a primary LSP at a specified interval. The PLR searches for the optimal TE bypass CR-LSP and binds it to a primary CR-LSP. A TE FRR scanning timer is set to determine the interval at which the binding between a bypass CR-LSP and a primary CR-LSP is refreshed.

Perform the following configurations on the PLR.

Procedure

  1. Run system-view

    The system view is displayed.

  2. Run mpls

    The MPLS view is displayed.

  3. Run mpls te timer fast-reroute [ weight ]

    Set the interval at which the binding between a bypass CR-LSP and a primary CR-LSP is refreshed.

    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.
