It is a layer 2 VPN tunnel or at least one end of a VPN tunnel. In effect it is extending a L2 vlan across a L3 routed IP network ie. you can have the same L2 broadcast domain in 2 different locations separated by a L3 network.

So if a client in site 1 sends out a broadcast to it's local subnet machines on the same subnet in site 1 will see the broadcast as will the machines in site2 that are part of the extended vlan.
