Hi,
You are right it is 10 Sec and not 30 Sec as I mentioned earlier. You might
want to check the IOS version. I am running on 12.1.
A point-to-multipoint network on an NBMA environment is just a collection of
point-to-point networks. There is no timer difference between them. Its
10Sec & 40Sec for the hello and dead interval respectively.
Referring the original posting of this thread, there is no need to adjust
the timers on any of the Routers.
thanks
Robert M
