IPv6 MCE configuration
Overview
In an IPv6 MPLS L3 VPN, an IPv6 MCE advertises IPv6 routing information between the VPN and the
connected PE and forwards IPv6 packets. An IPv6 MCE operates in the same way as an IPv4 MCE. For
more information, see the chapter ”MCE configuration.”
Configuring an IPv6 MCE
Configuring VPN instances
By configuring VPN instances on a PE, you isolate not only VPN routes from public network routes, but
also routes of a VPN from those of another VPN. This feature allows VPN instances to be used in network
scenarios besides MPLS L3VPNs.
Creating a VPN instance
A VPN instance is associated with a site. It is a collection of the VPN membership and routing rules of its
associated site. A VPN instance does not necessarily correspond to one VPN.
A VPN instance takes effect only after you configure an RD for it.
You can configure a description for a VPN instance to record its related information, such as its
relationship with a certain VPN.

Associating a VPN instance with an interface
After creating and configuring a VPN instance, you need to associate the VPN instance with the interface
for connecting the CE. Any LDP-capable interface can be associated with a VPN instance. For
information about LDP-capable interfaces, see the chapter “MPLS basics configuration.”
