Based on the need to limit processing and bandwidth utilization due to dynamic routing protocol
operation, the following routing requirements have been specified for your network.
– Partial and incremental routing updates
– Only the devices affected by a topology change perform route recomputation
– Route recomputation only occurs for routes that were affected
Which dynamic routing protocol should be deployed in your network to best meet these
requirements?
A.
BGP
B.
OSPF
C.
IS-IS
D.
EIGRP
E.
RIPv2
Explanation:
The bandwidth utilization issue has been addressed by implementing partial and incremental
updates. Therefore, only when a topology change occurs does routing information get sent.
Regarding processor utilization, the feasible successor technology greatly reduces the total
processor utilization of an AS by requiring only the routers that were affected by a topology
change to perform the route recomputation. Furthermore, the route recomputation only occurs for
routes that were affected. Only those data structures are accessed and used. This greatly reduces
search time in complex data structures.
