Hey guys. I'm nearly at the end of my studies for the written and one area I'm very very weak on is frame-relay and NBMA networks. Can anyone point me in teh right direction for some extra study material on this topic area?
I have the IPE written course, but there's nothing in it for frame-relay - not of any depth. I guess I need some practice lab stuff to get my head around it.
