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






 

Suggested Answer: D

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.
