Ive got this working..

The cisco is gladly adding the RIP updates from the portmaster to its
routing table, and redistributing them to other hosts via ospf.

my cisco's setup is

cisco 2516 IOS 10.3(11)

router ospf 99
redistribute static <redist static routes>
redistribute rip <redist routes learnt by rip>
network 203.20.104.0 0.0.0.63 area 0.0.0.0 <the backbone>
network 203.20.104.64 0.0.0.63 area 0.0.0.1 <another network>
neighbor 203.20.104.4 priority 3 <i486 routers running gated>
neighbor 203.20.104.1 priority 2 <i486 routers running gated>

router rip
redistribute static <redist static routes>
redistribute ospf 99 <redist routes learnt by ospf>
network 203.20.104.0 <the backbone>
neighbor 203.20.104.6 <the portmaster>

The portmaster is setup to Listen, Broadcast.

One thing you should check is the broadcast address of your PM, mine was set to "low" as default, which is wrong, it should be "high".

One thing tho, the PM does get the static routes via RIP.

Yes..

I used tcpdump port 520 and it certainly is broadcasting something, but
if I cant get an answer here I will be doing extensive debugging.
