HI All,

Could somebody please explain the difference between using ospf network
type point-to-multipoint and point-to-multipoint nonbroadcast.

The only difference I could read on the doc cd's was that with the added
nonbroadcast option you can use neighbor statement and assign costs to
the neighbor spokes to distinguish between more or less preferred links.

But I did the same thing with just using the p2m option without using
nonbroadcast and was able to assign the cost to the spokes.
Then why do we need the nonbroadcast????

Also another question-IF ospf should send ONLY unicast messages to the
neighbor, then the only option would be to use nbma with neighbor
command or is there any other option available which is send unicast??

Thanx,
Mohit.
