Checking the Configurations

Checking the Configurations

After configuring a P2MP TE tunnel, you can view information about the tunnel when it is in the Up state.

Prerequisites

A P2MP TE tunnel has been configured.

Procedure

  • Run the display mpls te p2mp tunnel-interface command to check information about the P2MP TE tunnel interface on the ingress and all sub-LSPs.
  • Run the display mpls te p2mp-template command to check P2MP TE tunnel template configurations and information about P2MP TE tunnels established using this template.
  • Run the display mpls te leaf-list command to check information about the leaf list configured on the ingress.
  • Run the display mpls te p2mp tunnel path command to check the path attributes of the P2MP TE tunnel.
  • Run the display mpls multicast-lsp protocol p2mp-te command to check the sub-LSP status and MPLS forwarding entries, including the incoming label, outgoing label, inbound interface, and outbound interface of each sub-LSP.
  • Run the display mpls multicast-lsp statistics protocol p2mp-te command to check statistics about sub-LSPs that pass through a local node.
  • Run the display mpls rsvp-te p2mp lsp command to check information about RSVP signaling of the P2MP LSP.
  • Run the display mpls rsvp-te p2mp statistics command to check statistics about the RSVP signaling packets sent and received over the P2MP TE tunnel.
  • Run the display mpls rsvp-te p2mp session command to check information about RSVP P2MP sessions.

Example

After configuring a P2MP TE tunnel, run the following commands to check whether the configuration has taken effect.

Run the display mpls te p2mp tunnel-interface command to view information about the P2MP TE tunnel interface on the ingress and all sub-LSPs. The command output shows that the tunnel is Up, and each sub-LSP is Up.

Run the display mpls te leaf-list verbose command to view information about each leaf list configured on the ingress and used by each tunnel.

Run the display mpls te p2mp tunnel path command to check the path attributes of the P2MP TE tunnel.
NOTE:

Before running the display mpls te p2mp tunnel path command, run the mpls te record-route [ label ] command to enable the route and label recording functions.

The command output shows the path information of each sub-LSP over the P2MP TE tunnel and the label assigned to each network segment.
