For those of us like me who are working towards CCIE, you are certainly aware of the fact that CCIE v4 will be raised to v5. For INE.com, it seems that Frame-Relay (replaced by DMVPN), and some other features will be replaced.
I am studying really for fun now : I am studying Frame-Relay now 🙂
Frame-Relay : just for fun… v5 will come out shortly.
I was starting to studying Multicast, but after reading this INE’s article I decided to postpone it 🙂
