The printer may be sending out RIP packets and this is confusing routed. It is killing attempts to add routes to the printer because they are malformed -- they don't list a gateway, which implies that someone is trying to add a default route to the printer. Is it possible to disconnect the printer from the net for a while and see if the errors persist? Can you look at the printer's settings and change them to be less annoying about routing? You have no traffic to the printer so I assume it doesn't get a lot of use (by `server' at least). > On the same wire are also two HP-UX machines running gated without complains, > but since almost half of HP-UX is broken they are no reference. We have gated available as a port for FreeBSD if you're more comfortable working with it. > The crazy thing is, I can't see anything on the network coming from > the printer (192.168.21.92). Or I am doing something wrong with tcpdump... I'm tempted to try turning the printer off for a while and see if that shuts up routed. How is the printer interfaced, by TCP/IP or by Apple EtherTalk? I see that netatalk is built into server's kernel so it understands AppleTalk -- it may be trying to add routes for it and routed doesn't understand AppleTalk. I'm tempted to point the finger of blame at the printer unless one of your hosts is misconfigured to use it's IP and is hiding behind something so that FreeBSD doesn't pick it up as a ARP overwrite.
