I'm here in the UK - cost me £43 - Amazon have it at £35ish but with 1-2
week backlog. I got it from a specialst IT-type bookshop in London - one of
my collegues recommended it on the cisco-nsp mail-list.
As I said it seems like one of those books set to go up with Halabi,
Doyle,et al for those serious about the subject matter - not really a cert
book, but essential for those running high-end routers, particularly ISP BGP
stuff. I have scoured CCO for good stuff about the different switching
methods - opened a TAC case one time, but it's simply not there....
excellent book - go get it from wherever :-)
take care
Andy
