Verifying the Configuration of Static BFD for TE Tunnels

Prerequisites

The configurations of static BFD for TE tunnels are complete.

Procedure

Run the display bfd configuration mpls-te interface tunnel interface-number [ verbose ] command to check BFD configurations on the ingress.
Run the following commands to check BFD configurations on the egress:
- Run the display bfd configuration all [ for-ip | for-lsp | for-te ] [ verbose ] command to check all BFD configurations.
- Run the display bfd configuration static [ for-ip | for-lsp | for-te | name cfg-name ] [ verbose ] command to check the static BFD configurations.
- Run the display bfd configuration peer-ip peer-ip [ vpn-instance vpn-instance-name ] [ verbose ] command to check the configurations of BFD with the reverse path being an IP link.
- Run the display bfd configuration static-lsp lsp-name [ verbose ] command to check the configurations of BFD with the reverse path being a static LSP.
- Run the display bfd configuration ldp-lsp peer-ip peer-ip nexthop nexthop-address [ interface interface-type interface-number ] [ verbose ] command to check the configurations of BFD with the backward channel being an LDP LSP.
- Run the display bfd configuration mpls-te interface tunnel interface-number te-lsp [ verbose ] command to check the configurations of BFD with the backward channel being a CR-LSP.
- Run the display bfd configuration mpls-te interface tunnel interface-number [ verbose ] command to check the configurations of BFD with the backward channel being a TE tunnel.
Run the display bfd session mpls-te interface tunnel interface-number [ verbose ] command to check BFD session configurations on the ingress.
Run the following commands to check BFD session configurations on the egress:
- Run the display bfd session all [ for-ip | for-lsp | for-te ] [ verbose ] command to check all the BFD configurations.
- Run the display bfd session static [ for-ip | for-lsp | for-te ] [ verbose ] command to check the static BFD configurations.
- Run the display bfd session peer-ip peer-ip [ vpn-instance vpn-instance-name ] [ verbose ] command to check the configurations of BFD with the backward channel being an IP link.
- Run the display bfd session static-lsp lsp-name [ verbose ] command to check the configurations of BFD with the backward channel being a static LSP.
- Run the display bfd session ldp-lsp peer-ip peer-ip nexthop nexthop-address [ interface interface-type interface-number ] [ verbose ] command to check the configurations of BFD with the backward channel being an LDP LSP.
- Run the display bfd session mpls-te interface tunnel interface-number te-lsp [ verbose ] command to check the configurations of BFD with the backward channel being a CR-LSP.
- Run the display bfd session mpls-te interface tunnel interface-number [ verbose ] command to check the configurations of BFD with the backward channel being a TE tunnel.
Run the following command to check BFD statistics:
- Run the display bfd statistics session all [ for-ip | for-lsp | for-te ] command to check all BFD session statistics.
- Run the display bfd statistics session peer-ip peer-ip [ vpn-instance vpn-instance-name ] command to check statistics about the BFD session that detects faults in the IP link.
- Run the display bfd statistics session static-lsp lsp-name command to check statistics about the BFD session that detects faults in the static LSP.
- Run the display bfd statistics session ldp-lsp peer-ip peer-ip nexthop nexthop-address [ interface interface-type interface-number ] command to check statistics of the BFD session that detects faults in the LDP LSP.
- Run the display bfd statistics session mpls-te interface tunnel interface-number te-lsp command to check statistics about the BFD session that detects faults in the CR-LSP.
- Run the display bfd statistics session mpls-te interface tunnel interface-number command to check statistics on BFD sessions for TE tunnels.
