Function

The display mpls multicast-lsp protocol mldp command displays forwarding plane information about multicast LSPs.

Format

display mpls multicast-lsp protocol mldp p2mp [ root-ip root-ip-address { lsp-id lsp-id | opaque-value opaque-value } ] [ lsr-role { ingress | transit | egress | bud } ]

Parameters

Parameter	Description	Value
root-ip root-ip-address	Displays forwarding plane information on a multicast P2MP LSP that originates from a specified root node.	The value is in dotted decimal notation.

Usage Guidelines

Usage Scenario

To view forwarding plane information on a multicast P2MP LSP, run the display mpls multicast-lsp protocol mldp p2mp command on each node. Only P2MP LSPs can be used as multicast LSPs.

If no parameters are specified, the command output contains forwarding plane information on all multicast P2MP LSPs.

Example

The actual command output varies according to the device. The command output here is only an example.
