Each router (RTA, RTB, and RTC) has one iBGP adjacency with the route reflector router
RTD. Router RTC has an iBGP route advertised by RTA, but the same route is missing from
RTB. The network engineer verifies that route filtering does not deny the route
advertisement. Which action corrects the problem?
A.
RTD(config-router)#neighbor 192.168.1.1 route-reflector-client
RTD(config-router)#neighbor 192.168.1.1 description RTA
RTD(config-router)#neighbor 192.168.1.2 route-reflector-client
RTD(config-router)#neighbor 192.168.1.2 description RTB
B.
RTC(config-router)#neighbor 192.168.1.4 route-reflector-client
RTC(config-router)#neighbor 192.168.1.4 description RTD
C.

D.
