"ip ospf mtu-ignore" on the interfaces in question this is as good a place as any to plug Parkhurst's OSPF Command and Configuration Handbook, which I got myself for Christmas. Like the BGP book, this one goes through all the ommands, and contains a lot of information which, while in the Cisco documentation, may not be easily found or clearly explained. I haven't done enough with this book to have a clear opinion of it, but I do believe that more training books should take this approach. I imagine the reason they don't is the sheer hard boring work for the author, the editors, and the tech reviewers. The good thing is that many of the examples can be tested with only two routers, and even the more complex example use only 3 or 4 routers, yet make their point quite clearly. > > Thanks. > Faisal Khan > CCIE Candidate.
