Open the PT Activity. Perform the tasks in the activity instructions and then answer the question.

Which task has to be performed on Router 1 for it to establish an OSPF adjacency with Router 2?

  • Issue the clear ip ospf process command.
  • Remove the passive interface command from interface FastEthernet 0/0.
  • Add the network area 0 command to the OSPF process.
  • Change the subnet mask of interface FastEthernet 0/0 to
    Answers Explanation & Hints:

    Each interface on the link connecting the OSPF routers must be in the same subnet for an adjacency to be established. The IP address subnet mask on FastEthernet interface 0/0 must be changed to The FastEthernet interface 0/0 is not passive. The network is only connected to Router2 so should not be advertised by Router1. The clear ip ospf process command will start the OPSF process on Router1 but will not cause an adjacency to be established if the subnet mask mismatch on the connecting interfaces still exists.
