Networking - EIGRP and OSPF
11. What are reasons for creating OSPF in a hierarchical design?

    To decrease routing overhead
    To speed up convergence
    To confine network instability to single areas of the network
    To make configuring OSPF easier

14. You get a call from a network administrator who tells you that he typed the following into his router:

Router(config)#router ospf 1
Router(config-router)#network 10.0.0.0 255.0.0.0 area 0

He tells you he still can't see any routes in the routing table. What configuration error did the administrator make?

  • The wildcard mask is incorrect.
  • The OSPF area is wrong.
  • The OSPF Process ID is incorrect.
  • The AS configuration is wrong.
