Usage Guidelines

Usage Scenario

If P2MP TE tunnels are established to transmit NG MVPN and multicast VPLS services, P2MP TE FRR can be configured to protect P2MP TE tunnels, which improves network reliability. To enable P2MP TE FRR, run the fast-reroute command in the P2MP tunnel template view.

Prerequisites

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