When building an interprovider VPN, you notice on the PE router that you have hidden routes which are received from your BGP peer with family inet labeled-unica3t configured.

Which parameter must you configure to solve this problem?

A.
Under the family inet labeled-unicast hierarchy, add the explicit null parameter.
Answers
A.
Under the family inet labeled-unicast hierarchy, add the explicit null parameter.
B.
Under the protocols ospf hierarchy, add the traffic-engineering parameter.
Answers
B.
Under the protocols ospf hierarchy, add the traffic-engineering parameter.
C.
Under the family inet labeled-unicast hierarchy, add the resolve-vpn parameter.
Answers
C.
Under the family inet labeled-unicast hierarchy, add the resolve-vpn parameter.
D.
Under the protocols mpls hierarchy, add the traffic-engineering parameter
Answers
D.
Under the protocols mpls hierarchy, add the traffic-engineering parameter
Suggested answer: C

Explanation:

The resolve-vpn parameter is a BGP option that allows a router to resolve labeled VPN-IPv4 routes using unlabeled IPv4 routes received from another BGP peer with family inet labeled-unicast configured. This option enables interprovider VPNs without requiring MPLS labels between ASBRs or using VRF tables on ASBRs. In this scenario, you need to configure the resolve-vpn parameter under [edit protocols bgp group external family inet labeled-unicast] hierarchy level on both ASBRs.
