OSPF - Got another one for ya...

Sorry to keep peppering you boys with all these questions... just trying to fill any grey areas I have with solid knowledge.

Was considering yesterday questions that might pop up on my exam next Thursday and considered that there could be a question on OSFP Authentication. If a question were to pop up about OSPF Routers having trouble forming adjacencies (which it most likely will) how can I check that the two Routers in question are both using the same MD5 ID key (1-255) and the same password? I'd look into this myself (and already have) but all I have is the Boson simulator which doesn't support this and I’ve found is about as much to me as condoms are to eunuch.

Thanks to anyone who responds.

You can use the debug and it will show authentication faliure.

The debug ip ospf events command?

The debug ip ospf events and debug ip ospf packets will both show the authentication failure I believe. The events command is the more commanly used from my experience.

Host the image at something like photobucket.com, then paste the image URL between [img][/img]

Also don't forget about the need for matching Subnet Numbers, Subnetmasks, hello/dead intervals, and area ID when establishing a neighbor. I don;t think you should worry too much about hashing and authentication untill November. IN which case you would already be a CCNA.
