Question Image

Which of the following is not configured on dcgw10 to support Layer 3 VPN connectivity?

  • A The base BGP instance to support vpn-ipv4 and evpn address families.
  • B A routed VXLAN interface for the VPRN instance.
  • C A binding of the VPRN instance to the MPLS tunnels towards dcgw20.
  • D A vrf-target matching the vrf-target on dcgw20 in the VPRN instance.
Explanation

A VPRN distributes customer routes using MP-BGP VPN-IPv4 and route-target import/export policy, while the local IP-VRF can attach through a routed EVPN/VXLAN interface. MPLS transport to the remote PE is selected by automatic tunnel binding that resolves the MP-BGP next hop; there is no direct VPRN binding specifically to MPLS tunnels toward dcgw20.
