what's everyone working on right now?
I've just gotten the basics of IPsec down and now working on the NHRP part of DMVPN. I find it to be a very interesting piece of technology, perhaps the most interesting thing I've studied so far. Seeing the development from crypto map based ipsec to gre+ipsec to VTI to DMVPN is just plain cool. A small piece of networking history in a way that you don't see when studying the routing protocols since the old ones are dead and buried.
