I was reading through few pages in the bookstores. I was struck by the fact that the author had stripped open EIGRP. And EIGRP is popular but Cisco documentation is crappy on this. Now the only place I looked at EIGRP packets was on the sniffer in our place, even I never found that on Cisco web pages including the Open Forum. It's well organised. The author knows his stuff and of course deserves a big hand. I shall definitely buy this because it's more professional than Cisco documentation.
