(NB: The following networks are not Internet-connected, even though i'm using domain names. They form a private IP network.) tcd-dresden.de does have two machines on its local ethernet that are acting as routers. lam.tcd-dresden.de is often running PPP over ISDN to connect the network to eat-kempen.de. As long as the link is ready, it should be announced within tcd-dresden.de's ethernet, so all hosts can reach the hosts @eat-kempen.de. bonnie.tcd-dresden.de does have a modem, and occasionally people are logging in through the modem and run SLIP. As soon as somebody did this, his host route shall also be announced throughout the ethernet so he can use all hosts out of tcd-dresden.de. (It's not necessary to exchange routing information for this via lam's PPP link.) There are several hosts that could log in via SLIP, they do have a variety of IP addresses (sometimes out of the range that's normally belonging to tcd-dresden.de's class C net, but not necessarily). Right now i've been solving this running gated's on the gateways that are going to forward RIP announcements to the ethernet, and have routed -q's (listening-only routed's) on all non-gateway hosts, so they can adjust their kernel routing tables as soon as some of the external routes are being announced. Everything is working as desired. I'm curious how to solve this withouth routed's. -- cheers, J"org joerg_wunsch@uriah.heep.sax.de -- http://www.sax.de/~joerg/ Never trust an operating system you don't have sources for. ;-)
