mldp p2mp topo

Function

The mldp p2mp topo command creates a primary mLDP P2MP LSP in the class-specific topology.

The undo mldp p2mp topo command restores the default configuration.

By default, no primary mLDP P2MP LSP is created in the class-specific topology.

Format

mldp p2mp topo topology-name

undo mldp p2mp topo topology-name

Parameters

Parameter	Description	Value
topology-name	Specifies the name of a topology instance.	The value is a string of 1 to 31 case-sensitive characters, with spaces supported. Generally, "base" is reserved for base topology instances and cannot be configured.

Usage Guidelines

Usage Scenario

When multicast traffic of NG MVPN services is properly forwarded, mLDP P2MP dual-root protection can be configured to improve multicast service reliability. If the mLDP LSPs created on the master and backup roots partially overlap, dual-root protection fails, causing traffic loss. To address this problem, run the mldp p2mp topo command to create the primary mLDP P2MP LSP in the class-specific topology.

Prerequisites

Ensure that the following steps have been performed:

A topology instance has been created using the ip topology command in the system view.
The mLDP P2MP capability has been enabled using the mldp p2mp command in the MPLS-LDP view.
