display mpls mldp lsp p2mp

Function

The display mpls mldp lsp p2mp command displays LDP signaling information on mLDP P2MP LSPs.

Format

display mpls mldp lsp p2mp [ root-ip root-ip-address { lsp-id lsp-id | opaque-value opaque-value } | name p2mp-lsp-name ]

Parameters

Parameter	Description	Value
root-ip root-ip-address	Displays information about a P2MP LSP with a specified root address.	The value is in dotted decimal notation.
lsp-id lsp-id	Displays information about a P2MP LSP with a specified LSP ID.	The value is an integer ranging from 0 to 4294967295.
opaque-value opaque-value	Displays information about a P2MP LSP with a specified opaque value.	The value is a hexadecimal string of 1 to 254 characters.
name p2mp-lsp-name	Displays information about a P2MP LSP with a specified name.	The value is a string of 1 to 31 case-sensitive characters. It cannot contain spaces. When double quotation marks are used around the string, spaces are allowed in the string.

Usage Guidelines

Usage Scenario

To view local mLDP P2MP LSP information, run the display mpls mldp lsp p2mp command. The command output helps check whether P2MP LSPs are successfully established using LDP signaling. The command output only contains information about successfully established P2MP LSPs.

Example

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