In one of the Cisco configuration guide I read: "
Before the IPv6 Provider Edge Router over MPLS (6PE) feature can be implemented, MPLS must be running over the core IPv4 network. If Cisco routers are used, Cisco Express Forwarding (CEF) or distributed CEF (dCEF) must be enabled for both IPv4 and IPv6 protocols. This module assumes that you are familiar with MPLS."
Does it means my interface on each and every routers should be dual stack to support the MPLS as it said to enable MPLS on IPv4 network?
so what if I have only IPv6 addressing in the network! and want to run MPLS VPN on IPv6 network?
how can i enable the MPLS in my IPv6 network?
