One of the options I'm currently consider is Router Discovery Protocol.
There is an RFC for this feature (I don't remember its number). RDISC
is provided in Baynetworks routers, I don't know whether cisco has it.
RDISC is available as a part of Solaris, and I believe there is an
implementation somewhere for Sun/OS, and probably for other Unix
platforms.

As to OSPF, a gated (gate daemon) is available from 
http://www.gated.merit.edu/~gated; there is also a usernet group
info.gated. Keep in mind however that ospf - as implemented by gated -
requires multicasting support. Make sure your UNIX supports it. 

With only two default routers, though, I would go for RDISC. This will
be my situation pretty soon ('router redundancy project').
