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.
The system view is displayed.
The MPLS view is displayed.
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.
