  1. If you run a Wireshark cap you can see the plain-text passphrase of MYPASS in one of the OSPF header packets

  2. Hi Sudej,

    If you enable authentication for the entire area then you still have to configure the password on the interface.

  3. HI Rene,

    This seems like bad design by Cisco or ignorance on my part. Why enable authentication at the area to save work but still have to go into each interface to add the key?

    I can only think they know something I don’t or they would have made it where you can do both at the global level… anyway thanks for clarifying!

  4. Hello Brian

    The reason the key must be configured on the interface is because each link between two OSPF routers can have a different key. The keys are not global but are specific to the interfaces being connected.

    I hope this has been helpful!
