Which parameter must you configure to solve this problem?

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.
B. Under the protocols ospf hierarchy, add the traffic-engineering parameter.
C. Under the family inet labeled-unicast hierarchy, add the resolve-vpn parameter.
D. Under the protocols mpls hierarchy, add the traffic-engineering parameter

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.
