In the diagram below, an end-to-end transport tunnel needs to be established between PE1 and PE2 using MP-BGP. Which of the following items is NOT required?
A.
MP-BGP address families label-ipv4 or label-ipv6 need to be supported on each of the edge routers.
B.
Either RSVP, LDP, or segment routing tunnels need to be established between regions.
C.
Either RSVP, LDP, or segment routing tunnels need to be established within each region.
D.
Each PE router needs to advertise an IP address as a labeled BGP route to identify the tunnel endpoint.
The tunnel endpoint in MPLS is usually identified by the labels that are advertised, not by IP addresses. PE routers exchange labels for the VPN or service endpoints, not specifically IP addresses tied to the transport tunnel.
