Fast IPAn IP switching technique from 3Com. The originating machine sends the first packet to the router, which forwards it to its destination. The destination machine sends back a response using the sender's layer 2 address. If the sending machine receives the response, it knows there is a direct connection without going through the router and forwards the remaining packets via layer 2. Fast IP uses a modified version of the NHRP protocol.
