Verifying the Configuration of Static BFD for TE

Verifying the Configuration of Static BFD for TE

After configuring static BFD for TE, you can view configurations, such as the status of the BFD sessions.

Prerequisites

Static BFD for TE has been configured.

Procedure

  • Run the display bfd session mpls-te interface tunnel-name [ verbose ] command to check information about BFD sessions on the ingress.
  • Run the following commands to check information about BFD sessions on the egress.

    • Run the display bfd session all [ for-ip | for-lsp | for-te ] [ verbose ] command to check information about all BFD sessions.
    • Run the display bfd session static [ for-ip | for-lsp | for-te ] [ verbose ] command to check information about static BFD sessions.
    • Run the display bfd session peer-ip peer-ip [ vpn-instance vpn-name ] [ verbose ] command to check information about BFD sessions with reverse IP links.
    • Run the display bfd session ldp-lsp peer-ip peer-ip [ nexthop nexthop-ip [ interface interface-type interface-number ] ] [ verbose ] command to check information about BFD sessions with reverse LDP LSPs.
    • Run the display bfd session mpls-te interface tunnel-name te-lsp [ verbose ] command to check information about BFD sessions with reverse CR-LSPs.
    • Run the display bfd session mpls-te interface tunnel-name [ verbose ] command to check information about BFD sessions with reverse TE tunnels.

  • Run the following commands to check BFD statistics.

    • Run the display bfd statistics session all [ for-ip | for-lsp | for-te ] command to check statistics about all BFD sessions.
    • Run the display bfd statistics session static [ for-ip | for-lsp | for-te ] command to check statistics about static BFD sessions.
    • Run the display bfd statistics session peer-ip peer-ip [ vpn-instance vpn-name ] command to check statistics about BFD sessions with reverse IP links.
    • Run the display bfd statistics session ldp-lsp peer-ip peer-ip [ nexthop nexthop-ip [ interface interface-type interface-number ] ] command to check statistics about BFD sessions with reverse LDP LSPs.
    • Run the display bfd statistics session mpls-te interface interface-type interface-number te-lsp command to check statistics about BFD sessions with reverse CR-LSPs.

Example

After completing the configurations, run the display bfd session command. The command output shows that the BFD session status is Up, and the BFD session type is S_TE_TNL.
