Configuring Association Between TE FRR and CR-LSP Backup

After the primary CR-LSP is faulty, the system starts the TE FRR bypass tunnel and tries to restore the primary CR-LSP the same time it sets up a backup CR-LSP.

Pre-configuration Tasks

Before configuring association between TE FRR and CR-LSP backup, complete the following tasks:

Configure CR-LSP backup (except for the best-effort path) in either hot standby mode or ordinary backup mode. For details, see Configuring CR-LSP Backup.
Configure manual TE FRR or auto TE FRR. For details, see Configuring Manual TE FRR or Configuring Auto TE FRR.

Context

Association between TE FRR and CR-LSP backup protects the entire CR-LSP.

Perform the following configurations on the ingress node of the primary MPLS TE tunnel.

Procedure

Run system-view

The system view is displayed.
Run interface tunnel interface-number

The tunnel interface view of the MPLS TE tunnel is displayed.
Run mpls te backup frr-in-use

When the primary CR-LSP is faulty (that is, the primary CR-LSP is in FRR-in-use state), the system starts the bypass CR-LSP and tries to restore the primary CR-LSP. At the same time, the system attempts to set up a backup CR-LSP.
Run mpls te commit

The tunnel configurations are committed.

Verifying the Configuration

Run the display mpls te tunnel-interface [ tunnel interface-number | auto-bypass-tunnel [ tunnel-name ] ] command to view information about the tunnel.
