Configuring IPv6 MCE

This chapter describes IPv6 MCE configuration.

Overview

In MPLS L3VPN networks, MCE uses static routes or dynamic routing protocols to advertise IPv4 routes
between internal networks and PEs and forwards IPv4 packets.
In IPv6 MPLS L3VPN networks, IPv6 MCE uses IPv6 static routes and dynamic routing protocols to

advertise IPv6 routes between internal networks and PEs and forwards IPv6 packets. The fundamentals

of IPv6 MCE are the same as those of MCE. For more information, see "
