Verifying the CR-LSP Backup Configuration

Verifying the CR-LSP Backup Configuration

After configuring CR-LSP backup, you can view information about backup CR-LSPs.

Prerequisites

CR-LSP backup has been configured.

Procedure

  • Run the display mpls te tunnel-interface command to check information about a tunnel interface on the ingress of a tunnel.
  • Run the display mpls te hot-standby state { all [ verbose ] | interface tunnel-interface-name } command to check information about the hot-standby status.

Example

Run the following commands to check the previous configurations.

Run the display mpls te tunnel-interface command. The command output shows that the tunnel is Up.
