Refer to the exhibit. Service provider SP 1 is running the MPLS-VPN service. The MPLS core network has MP-BGP configured with RR-1 as route reflector. What will be the effect on traffic between PE1 and PE2 if router P1 goes down?
Correct Answer: D
Explanation/Reference: Explanation: If the connection to the route reflector goes down, then routes from PE-1 will not get advertised to PE2, and vice versa. Route reflectors are critical in an MPLS VPN such as the one shown, which is why it is a best practice to have multiple route reflectors in this kind of network.
