Cisco IOS XR MPLS Configuration Guide

OL-12284-01

Implementing MPLS VPNs over IP Tunnels on
Cisco IOS XR Software

The MPLS VPNs over IP Tunnels feature lets you deploy Layer 3 Virtual Private Network (L3VPN)
services, over an IP core network, using L2TPv3 multipoint tunneling instead of MPLS. This allows
L2TPv3 tunnels to be configured as multipoint tunnels to transport IP VPN services across the core
IP network.

Note

This feature is available on the Cisco XR 12000 Series Router only.
