Which two statements about 6VPE are true? (Choose two.)
A.
It allows a service provider to use an existing MPLS network to provide VPN services to IPv6
customers.
B.
It uses MP-BGP as the carrier protocol to transport IPv6 connectivity.
C.
It provides IPv6 connectivity to MPLS-VPN customers when IPv6 overlay tunneling is also
configured.
D.
It allows a service provider to use an existing MPLS network to provide global addressing to their
IPv6 customers.
E.
It requires the configuration of a GRE tunnel tagged with a VLAN ID.
F.
It allows a service provider to use an existing L2TPv3 network to provide VPN services to IPv6
customers.
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 dualstack
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
