Correct Answer: A,B
Explanation/Reference:
The IPv6 MPLS VPN service model is similar to that of IPv4 MPLS VPNs. Service providers who have already deployed MPLS IPv4 VPN services over an IPv4 backbone can deploy IPv6 MPLS VPN services over the same IPv4 backbone by upgrading the PE router IOS version and dual- stack configuration, without any change on the core routers. IPv4 services can be provided in parallel with IPv6 services. IPv6 VPN service is exactly the same as MPLS VPN for IPv4. 6VPE offers the same architectural features as MPLS VPN for IPv4. It offers IPv6 VPN and uses the same components, such as:
Multiprotocol BGP (MP-BGP) VPN address family
Route distinguishers
VPN Routing and Forwarding (VRF) instances
Site of Origin (SOO)
Extended community
MP-BGP
