A. The update information will be added to the existing routing table.
B. The update information will replace the existing routing table entry.
C. The update will be ignored and thus no further action will occur.

A. It will ignore the update and take no further action.
B. It will add the update information to its routing table.
C. It will replace the existing routing table entry with the update information.

C. RIP v1 is a classless routing protocol.
D. IGRP supports classless routing within the same autonomous system.
E. RIP v2 supports classless routing.

A. Only routers can split boundaries (horizons) between concentric networks.
B. Each AS must keep routing tables converged to prevent dead routes from being advertised across boundaries.
C. Networks can only remain fully converged if all information is sent out all active interfaces.
D. Information about a route should not be sent back in the direction from which the original update came.
E. Distance vector protocols need fall back routers that are responsible for momentary loops.
