Configuring IPv6 MCE
This chapter describes how to configure the IPv6 MCE function.
Overview
In an IPv6 MPLS L3 VPN, an IPv6 MCE advertises IPv6 routing information between the VPN site and the
connected PE and forwards IPv6 packets. An IPv6 MCE operates in the same way as an IPv4 MCE. For
more information, see "Configuring MCE."
Configuring VPN instances
By configuring VPN instances, you isolate not only VPN routes from public network routes, but also routes
of a VPN from those of another VPN.
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.
