Explanation:
Specify the mpls address family on the Fast Ethernet interface.
Specify the inet-vpn address family and unicast traffic type to enable BGP to carry IPv4 network layer
reachability information (NLRI) for VPN routes.
Incorrect Answers:
B, D: BGP is the configured inet address family, but inet-vpn is required.
C: The interface lacks the family mpls statement.
