Refer to the exhibit. The operations team is implementing an LDP-based configuration in the service-provider core network with these requirements: - RC must establish LDP peering with the loopback…

LDP session protection is used to maintain an LDP session even if the directly connected interface fails, by using a targeted LDP session over another path, and is not a prerequisite for initial peering.

The mpls ip command must be enabled on an interface for it to participate in LDP, allowing LDP hellos to be sent and received and LDP adjacencies to form over that interface. Without this command on RC's Gi2/0, LDP packets cannot be processed, preventing peering with RA.

Resetting LDP hello hold time and interval to default values might resolve timer-related issues, but it's not the fundamental step for enabling LDP on an interface.

While configuring mpls ldp router-id loopback0 is a requirement for RC's LDP router ID, it does not enable LDP itself on the interface, which is necessary for peering to establish.
