The OSM-2+4GE-WAN-GBIC+ is the only core facing module supported.
Before you configure VPLS, ensure that the network is configured as follows:
â¢Configure IP routing in the core so that the PE routers can reach each other via IP.
â¢Configure MPLS in the core so that a label switched path (LSP) exists between the PE routers.
â¢Configure a loopback interface for originating and terminating Layer 2 traffic. Make sure the PE routers can access the other router's loopback interface. Note that the loopback interface is not needed in all cases. For example, tunnel selection does not need a loopback interface when VPLS is directly mapped to a TE tunnel.
This document is an early notification of a behaviour change that will be introduced in IOS XR release 6.5.
