I am in process of setting up a VPN service for HQ
to branch office for multiple customers(about 30 locations in all). The links to the central site would be either leased lines - 128/256k of
satellite links in the same BW range. What type of cisco router/concentrator should I deploy at the central site? 3660 ? do I need a VPN 3000 Concentrator ? Should I use IPsec or MPLS?
