Which three describe the reasons large OSPF networks use a hierarchical design? (Choose three.)
A) to speed up convergence
B) to reduce routing overhead
C) to lower costs by replacing routers with distribution layer switches
D) to decrease latency by increasing bandwidth
E) to confine network instability to single areas of the network
F) to reduce the complexity of router configuration

Question

Quizplus · Accepted Answer

A hierarchical OSPF design speeds up convergence by limiting the scope of topology changes, reduces routing overhead by minimizing the number of routes each router must maintain, and confines network instability to single areas, preventing issues from affecting the entire network.
