Cisco CRS Configuration Guide

Configuring Point-to-Multipoint TE
You must enable multicast routing on the edge router before performing Point-to-Multipoint (P2MP) TE
configurations. To configure Point-to-Multipoint TE, perform these procedures:
Enabling Multicast Routing on the Router
Perform this task to enable multicast routing on the router to configure P2MP tunnels.
Before You Begin
•
To configure Point-to-Multipoint (P2MP) tunnels, you must enable multicast routing on the router.
•
The customer-facing interface must enable multicast.
