Configuring Association Between TE FRR and CR-LSP Backup
Pre-configuration Tasks
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.
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.
