Hi, Amongst the zillion books available on VPN - am wondering if there is any good place to start to understand and support enterprise VPNs. I am not too keen on the 'dummies' version. CCO documentation is good - but looking for a primer/starter on the technology leading to design and support
I have a CCNP cert with background in support/install/maintain intranet lan/wan. But not much exposure to VPNs. Hence the search.
thanks in advance
