Verifying the Configuration of mLDP P2MP LSP

Verifying the Configuration of mLDP P2MP LSP

After configuring an mLDP P2MP LSP, verify mLDP P2MP LSP information on each node along the LSP and mLDP P2MP LSP connectivity on the root node (ingress).

Prerequisites

An mLDP P2MP LSP has been configured.

Procedure

  • Run the ping multicast-lsp mldp p2mp root-ip root-ip-address { lsp-id lsp-id | opaque-value opaque-value } command to check mLDP P2MP LSP connectivity on the root node.
  • Run the display mpls mldp lsp p2mp [ root-ip root-ip-address { lsp-id lsp-id | opaque-value opaque-value } ] command to check mLDP P2MP LSP information on a local node.
  • Run the display mpls multicast-lsp protocol mldp p2mp [ root-ip root-ip-address { lsp-id lsp-id | opaque-value opaque-value } ] [ lsr-role { bud | ingress | transit | egress } ] command to check mLDP P2MP LSP forwarding information.

Example

# Run the ping multicast-lsp mldp p2mp command on the root node to check mLDP P2MP LSP connectivity.

<HUAWEI> ping multicast-lsp mldp p2mp root-ip 1.1.1.1 lsp-id 100
  LSP PING FEC: root-ip 1.1.1.1 lsp-id 100 : 100  data bytes, press CTRL_C to break
