The Gateway commitee is working on an RFC about Routing in the Host IP Layer which talks about the others (e.g. finding gateways, etc.) We want to insulate the hosts as much as possible from the details of routing since we are going to be changing that, so having routing tables sent to hosts is out. Remember also that whatever mechanisms we use have to also work on nets that do not support broadcast. Noel -------
