What are reasons for creating OSPF in a hierarchical design?
1.To decrease routing overhead
2.To speed up convergence
3.To confine network instability to single areas of the network
4.To make configuring OSPF easier
Answer: A
OSPF is created in a hierarchical design, not a flat design like RIP. This decreases routing overhead, speeds up convergence, and confines network instability to a single area of the network.
