Question

Which two commands are required for basic OSPF configuration?

(a) “[Network mask] area [area-id]” and “Router ospf [process-id]”

(b) “[Wildcard-mask] area [area-id]” and “[Network mask] area [area-id]”

(c) Only “Router ospf [process-id]”

(d) “[Wildcard-mask] area [area-id]” and “Router ospf [process-id]”

I got this question by my college professor while I was bunking the class.

Question is from OSPF Configuration topic in chapter Network Layer of Computer Network

Answer 1

The correct choice is (d) “[Wildcard-mask] area [area-id]” and “Router ospf [process-id]”

To explain I would say: The “Router ospf [process-id]” command enables OSPF routing protocol in the router and the “[Wildcard-mask] area [area-id]” command is used to select the interfaces that we want to include in the OSPF process. That is enough for the basic configuration of OSPF in a router.
