When we have routing table cleaned up (e.g. remove arp off of it), I'll look into getting out some patch for installing /32 host routes for all receive-adjacent addresses. This way we don't have to run a hash lookup at ip_fastforward() to find out whether address belongs to us. We can simply either route it to lo0 as a receive-path (like in Cisco GSR/7500 rcvpath and Juniper loopback path) or send it to a separate input handling routine with packet filtering before returning to ip_input. Unless ofcourse, someone already has it made up and ready to go -- in that case there is no need ;) Thanks, -J -- James Jun TowardEX Technologies, Inc.
