Look at the config of Your cisco box, section 'router rip'. Did You
define a default metric like this ?

router rip
redistribute static
redistribute eigrp 5
network 194.59.222.0
default-metric 1 <---- this is important !!!

Doing not so may put the route into 'unreachable' state.

I'm running Linux 2.0.33 plus gated in a cisco routing environment
with much success. You may wish to enable rip version 2 support both
in cisco's and the gated config to get the advantage of subnet based
routing (CIDR :== classless interdomain routing) while still using
RIP. This however makes it necessary to enable 'allmulti' on your
Linux ifonfig parameters.
