Following the ideas of ITIL (Information Technology Infrastructure Library), I believe the term is site to site VPN meaning that a whole network is being connected to a whole network over a VPN connection of whatever type is specified. This is contrast to a RAS VPN where one individual host out in the world establishes a VPN back to a network.
There are many ways to do a VPN connection and many protocols to do it with. I am providing a sample of a 3DES encrypted and MD5 hash site to site VPN connection which uses a crypto map with an address range applied to an interface, similar to what you mentioned. You need an IOS image such as Advanced Security, Advanced IP Services, or Advanced Enterprise Services for this.
