We've just started using Ciscos here, and I ran into what seems to be a
pretty basic problem.  We've got a LAN that has two subnet numbers on it.
The Cisco has one number as its primary address for the interface, and one
as the secondary address.

The problem is that RIP broadcasts only come from the primary interface, so
some systems with the secondary subnet number are blind to the routing
information.  On top of that, some systems start logging "packet received
from unknown router" errors.

I'd rather not force a static default route on the LAN, because they do
have a backup router (a dual-interface PC) that can be switched in if the
Cisco's down, but only if the systems on the floor are running RIP and are
not hard-coded to route to the Cisco's address.

Anyone have any suggestions of what I can do here, either to get RIP
broadcasts sent twice, once from each address, or to get the systems on the
network to recognize RIP broadcasts with an alien source address and not
complain about them?
