Verifying the Configuration of a Dynamic MPLS TE Tunnel

Verifying the Configuration of a Dynamic MPLS TE Tunnel

Prerequisites

The configurations of a dynamic MPLS TE tunnel are complete.

Procedure

  • Run the display mpls te link-administration bandwidth-allocation [ interface interface-type interface-number ] command to check information about the allocated link bandwidth.
  • Run the display ospf [ process-id ] mpls-te [ area area-id ] [ self-originated ] command to check information about OSPF TE.
  • Run one of the following commands to check IS-IS TE information:
    • display isis traffic-eng advertisements
    • display isis traffic-eng link
    • display isis traffic-eng network
    • display isis traffic-eng statistics
    • display isis traffic-eng sub-tlvs
  • Run the display explicit-path [ [ name ] path-name ] [ tunnel-interface | lsp-attribute | verbose ] command to check configured explicit paths.
  • Run the display mpls te cspf destination ip-address [ affinity properties [ mask mask-value ] | bandwidth { ct0 ct0-bandwidth | ct1 ct1-bandwidth } * | explicit-path path-name | hop-limit hop-limit-number | metric-type { igp | te } | priority setup-priority | srlg-strict exclude-path-name | tie-breaking { random | most-fill | least-fill } ] * [ hot-standby [ explicit-path path-name | overlap-path | affinity properties [ mask mask-value ] | hop-limit hop-limit-number | srlg { preferred | strict } ] * ] command to check information about a path that is calculated using CSPF based on specified conditions.
  • Run the display mpls te cspf tedb { all | area { area-id | area-id-ip } | interface ip-address | network-lsa | node [ router-id ] | srlg srlg-number | overload-node } command to check information about TEDBs that can meet specified conditions and be used by CSPF to calculate paths.
  • Run the display mpls rsvp-te command to check RSVP information.
  • Run the display mpls rsvp-te established [ interface interface-type interface-number peer-ip-address ] command to check information about the established RSVP-TE CR-LSPs.
  • Run the display mpls rsvp-te peer [ interface interface-type interface-number ] command to check RSVP neighbor parameters.
  • Run the display mpls rsvp-te reservation [ interface interface-type interface-number peer-ip-address ] command to check information about RSVP resource reservation.
  • Run the display mpls rsvp-te request [ interface interface-type interface-number peer-ip-address ] command to check information about the RSVP-TE request messages on interfaces.
  • Run the display mpls rsvp-te sender [ interface interface-type interface-number peer-ip-address ] command to check information about RSVP senders.
  • Run the display mpls rsvp-te statistics { global | interface [ interface-type interface-number ] } command to check RSVP-TE statistics.
  • Run the display mpls te link-administration admission-control [ interface interface-type interface-number | stale-interface interface-index ] command to check the tunnels set up on the local node.
  • Run the display mpls te tunnel [ destination ip-address ] [ lsp-id ingress-lsr-id session-id local-lsp-id ] [ lsr-role { all | egress | ingress | remote | transit } ] [ name tunnel-name ] [ { incoming-interface | interface | outgoing-interface } interface-type interface-number ] [ verbose ] command to check tunnel information.
  • Run the display mpls te tunnel statistics or display mpls lsp statistics command to check tunnel statistics.
  • Run the display lsp-attribute [ name lsp-attribute-name ] [ tunnel-interface | verbose ] command to check the configurations of the CR-LSP attribute template and the tunnels using it.
  • Run the display mpls te tunnel-interface lsp-constraint [ tunnel interface-number ] command to view information about the CR-LSP attribute template on the TE tunnel interface.
  • Run the display mpls te tunnel-interface [ tunnel interface-number | auto-bypass-tunnel [ tunnel-name ] ] command to check information about the MPLS TE tunnel.
  • Run the display mpls te tunnel c-hop [ tunnel-name ] [ lsp-id ingress-lsr-id session-id lsp-id ] command to check path computation results of tunnels.
  • Run the display mpls te session-entry [ ingress-lsr-id tunnel-id egress-lsr-id ] command to check detailed information about the LSP session entry.
