My company plan to deploy site to site VPN. Right now, we have two proposals. One is to use Cisco router 7206 as VPN head-end, another is PIX 535. And two sides argue so much for that. Obviously PIX 535 is cheaper than 7206. If both proposal are same, is there any reason to use Cisco 7206?
My company network feature are:
1.IP based network
2.Run Oracle ERP system
3.Video or voice but outside VPN
5.maybe one hundred plus branches one day in future
We studied documnetations in Cisco web site , it seems they are equal.
This may just be my experience, or my confort zone, but I find that more complex site-to-site VPN's are better handled by an IOS device.
I use GRE over IPSec with EIGRP. The PIXen won't do that, as far as I know. Again, I may be missing something, but that lack of a "reload in x" command on the PIX makes remote configuration of crypto maps a bit more "exicting" than I like.
