Any help please mates?

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.
  • Change the subnet mask of interface FastEthernet 0/0 to 255.255.255.0.
  • Remove the passive-interface command from interface FastEthernet 0/0.
  • Add the network 10.0.1.0 0.0.0.255 area 0 command to the OSPF process.

Thanks a lot !

    Hey Aurora,

    Of course, with pleasure. Anyhow, This is the correct answer:

    • Change the subnet mask of interface FastEthernet 0/0 to 255.255.255.0.

    This one is easy to overthink. However, A is correct, but I am not serious, way too many possible answers could have made this a better question.

    Hi Stella,

    For me, I agree with A and this is the explanation I found :

    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 255.255.255.0. The FastEthernet interface 0/0 is not passive. The 10.0.1.0/24 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.

    May this helps to understand better the answer! Good luck..

    Terribly worded question, the answers actually tell you what the question is. This kind of question really makes my mind blow!

    Hi everybody,

    “A” would be my flag! I do some searches and the first statement seems the best answer for me.
