Study the Exhibit Carefully

Multiple Choice

Study the exhibit carefully. Routers P4S-RA, P4S-RB, P4S-RC, and P4S-RD are all performing OSPF within a single area and have OSPF graceful restart configured and running. 10.1.2.0/24 is being advertised only through BGP and the best path between routers P4S-RC and P4S-RD is through router P4S-RB. Configure BGP graceful restart on routers P4S-RB, P4S-RC, and P4S-RD, but not on router P4S-RA. What will happen to traffic from 10.1.1.0/24 to 10.1.2.0/24 after router P4S-RB performs a graceful restart?

A) be tunneled from router P4S-RD to router P4S-RA through router P4S-RC.
B) continue to flow normally
C) be dropped at router P4S-RB for a period of time after the graceful restart
D) switch to the path through router P4S-RC without interruption
