Verifying the IS-IS SR-MPLS TE Tunnel Configuration

Procedure

• Run the following commands to check the IS-IS TE status:
  • display isis traffic-eng advertisements [ lspId | local ] [ level-1 | level-2 | level-1-2 ] [ process-id | vpn-instance vpn-instance-name ]
  • display isis traffic-eng statistics [ process-id | vpn-instance vpn-instance-name ]
• Run the display mpls te tunnel [ destination ip-address ] [ lsp-id 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 sr-te-lsp command to check LSP statistics.
• Run the display mpls te tunnel-interface [ tunnel tunnel-number ] command to check information about a tunnel interface on the ingress.
• (Optional) If the label stack depth exceeds the upper limit supported by a forwarder, the controller needs to divide a label stack into multiple stacks for an entire path. After the controller assigns a stick label to a stick node, run the display mpls te stitch-label-stack command to check information about the stick label stack mapped to the stick label.
