We manage routing within our subnet very trivially - we don't really do routing, since we have only a single gateway to the outside world. I encourage our Sun owners to add a default route pointing to their own system, which adds a few ARPs to our local network, but finds the gateway just fine. What really is needed is a subnet routing protocol which passes netmasks along with the network numbers. Is anyone working on this yet? Can anyone tell me if 4.3bsd includes the netmask in each routing table entry? We need this to make such a protocol usable. Doug Nelson
