I have come across a fair amount of documentation about network types and OSPF (broadcast, non-broadcast, point-to-point, point-to-multipoint, point-to-multipoint non-broadcast.) It is generally clear how each of these behaves with regard to hello and dead timers, whether or not a DR election is held and if the hellos are sent via unicast or multicast.
One thing I have noticed is there seems to be a lot of inconsistent information concerning which of the network types are Cisco proprietary. I have read in some places that the broadcast network type is while others state that broadcast is a standard according the RFC. In some cases point-to-point, point-to-multipoint and point-to-multipoint non-broadcast are said to be Cisco proprietary, but others seem to disagree on one or another. I have searched for an opinion in Cisco’s documentation but could not find anything on this topic. Has anyone else come across this and have you found any reliable documentation to back it up? Much appreciated jpn _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
