At what level does the use of actual Cisco gear and IOS-run stuff become part of the equation for network planning and implementation? I guess this is part pole, part practical. It's kind of a broad question as well because I suppose it depends on application and environment. As this is a Mac forum I could also ask when does the Mac OS come into play (VPN software comes to mind)? Would anyone care to riff on scenarios when the use of Cisco stuff is the best option?
