Configuring IPv6 MCE

About IPv6 MCE

IPv6 MCE provides traffic separation between VPNs by distinguishing routes of the VPNs. It allows
multiple VPNs to share the same CE with ensured data security in an IPv6 MPLS L3VPN network.
IPv6 MPLS L3VPN uses BGP to advertise IPv6 VPN routes and uses MPLS to forward IPv6 VPN
packets on the service provider backbone.
IPv6 MCE uses the same working mechanism as MCE. It advertises IPv6 routes and exchanges
IPv6 packets between the internal network and the PE.
Restrictions and guidelines: IPv6 MCE
configuration
On the PE, disable routing loop detection to avoid route loss during route calculation, and disable
route redistribution between routing protocols to save system resources.
