I would like to know how many router and switches would be required to completely practise the CCNA Lab.
Thanks for your posts!
I guess to do Frame-Relay we would require 3 routers ?
Also which hardware i would need to simulate ISDN .
For frame relay lab you can use router acting as frame relay switch to have complete set for frame relay, check out the below link to the same :-
and for ISDN setup i would suggest rather going with physical hardware try with packet tracers or with simulators.
Hope to help !!
