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?
A.
No effect, because all traffic between PE1 and PE2 will be rerouted through P2.
B.
No effect, because P1 was not the only P router in the forwarding path of traffic.
C.
No effect, because RR-1 will find an alternative path for MP-BGP sessions to PE-1 and PE-2.
D.
All traffic will be lost because RR-1 will lose the MP-BGP sessions to PE-1 and PE-2.
