in CCNA & CCENT
Hi all,
I just got my myself some routers to play around with. I intend to take up the ccna certification. In fact, i've gone through the course few years ago, but did not take the exam due to work schedule. Well, sort of, everything went down the drain.
Anyway, I have 3 routers,
Cisco 2503
Cisco 2621 and wic-1t
Cisco 2620xm and wic-1t
1. If i want to practice frame-relay, can i configure 2503 as a frame relay switch? ... since it has 2 serial ports and i have two routers
2. But i see most people use a NM-4as for frame relay. Is there any scenarios that i need 2 physical serial interfaces for a router? i heard somewhere about multi link or multi point, care to explain?
3. and between wic-1t and WIC-1DSU-T1 in an home lab environment, any difference in terms of functionality? i think i can do frame relay with either one of them (using different cable types, of course), but any other differences?
I would appreciate if someone could clear some of my doubts.
thanks so much.
