eng-mssk: MPLS L3 VPN 6PE eBGP PE-CE Routing Protocol (Configuration)

Issue

We will configure IPv6 addressing between PEs and CEs and transport over the IPv4 MPLS backbone, i.e. 6VPE and eBGP will be the PE-CE routing protocol

Configuration

For the basic configuration of the L3 MPLS VPN please refer to http://eng-mssk.blogspot.com/2012/10/mpls-l3-vpn-ipv6-6pe.html

We will list current configuration of our elements
