Usage Guidelines

Usage Scenario

To use a leaf list to manage leaf nodes on an automatic P2MP TE tunnel, run the leaf-list command in the P2MP tunnel template view to reference an existing leaf list. This enables P2MP TE to use the configured leaf node addresses in the list and explicit paths to automatically establish P2MP TE LSPs.

Prerequisites

Ensure that the following tasks have been performed:

A leaf list has been configured using the mpls te leaf-list command.
A P2MP tunnel template has been configured using the mpls te p2mp-template command.

Example

# Create a leaf list named List1, a P2MP tunnel template named Template1, and reference the leaf list in the template view.
