You are redesigning an OSPF network that currently uses RFC 1918 Class A address space to optimize its convergence time. The entire network consists of point-to-point interfaces between routers. Which reason is the best reason to implement topology summarization in this network?
A) to optimize CEF entry allocation
B) to optimize RIB entry allocation
C) to reduce the number of neighbor relationships
D) to reduce link state database size

Question

Quizplus · Accepted Answer

Topology summarization reduces the size of the link-state database by aggregating routes, which can help optimize convergence time by minimizing the amount of information that needs to be processed and exchanged during topology changes.
