A network engineer is adding a new P router to the infrastructure and is connecting it to P1 and P3.Which task must the engineer perform on the new router to allow it to participate in the Layer 3 VPN?
B) Establish an LDP neighbor relationship with P1 and P3.
A) Enable LDP sync under the OSPF routing process.
C) Configure OSPF and BGP to support MPLS.
D) Enable LDP and establish an OSPF adjacency in a new area.

I wonder if enabling LDP and establishing an OSPF adjacency is necessary for the new router to fully integrate into the network. It sounds plausible.

I practiced a similar question where we had to configure OSPF and BGP for MPLS, but I can't recall if that's the main task here.

I think I remember something about needing to establish LDP neighbor relationships for MPLS to work properly. That might be important here.
