Please consult how configure StarOS and Cisco router! Unfortunately it malfunctions to me... OSPF between StarOS is OK.
StarOs and Cisco are connection over ethernet port. Cisco = 2621, StarOS is router edition v. 2.01.1 build 4590.
Cisco:
router ospf 10
log-adjacency-changes
network 10.1.10.0 0.0.0.3 area 0
StarOS:
router ospf
redistribute kernel
redistribute connected
redistribute static
network 10.1.10.0/30 area 0.0.0.0
Cisco#sh ip ospf nei
Neighbor ID Pri State Dead Time Address Interface
10.1.10.2 1 INIT/DROTHER 00:00:36 10.1.10.2 FastEthernet0/1.22
StarOS#sh ip ospf nei
Neighbor ID Pri State Dead Time Address Interface RXmtL RqstL DBsmL
Cisco recive OSPF Hallo, but next initialization fail...

I would suspect your mas 0.0.0.3 is wrong in the cisco. What size of subnet are you trying to use?

No... Itīs corect wild card bits for mask 255.255.255.252. Between Cisco and StarOS is subnet 10.1.10.0/30.

Have you checked that the MTU is the same on the Cisco and the StarOS router?

I had a similar problem, for cisco to see its neigboes all of the Star-OS boxes need to be on the same subnet as the primary IP of the interface faceing the Staros boxes. if u are affraid of broadcasts, then it is not a problem as long as everything is routed.
Try to assign a /27 to your cisco as primary and move over a couple of staros boxes to that subnet... ull see.

StarOS:
router ospf
redistribute kernel
redistribute connected
redistribute static
network 10.1.10.0/30 area 0.0.0.0
I don't have a Cisco box to play with but I could not get things to converge reliably until i removed the redistribute kernel option.
Also be aware that the redistribute static only redistributes Zebra's static routes, not static routes that are set in the routing menu. You can set these by telneting into the zebra client (127.0.0.1 port 2601) and using the configuration menu there
Here is a link to the zebra manual which may be helpful.
http://www.zebra.org/zebra/
The latest build of staros 4619 has a more recent version of Zebra than the build that you are using

Unfortunately remove redistribution kernel option won't help....
Thank you behind advice how redistributes static routes.

I've got two Ciscos talking to StarOS boxes without trouble. I don't see anything wrong with your config. I suspect that klyne's answer is what you need. It looks like the network you're trying to run OSPF on is a secondary IP on the Cisco. Try putting the StarOS box on the same network as the primary IP on the Cisco.
Incidentally, I'm running "redistribute kernel" on one of my StarOS OSPF boxes, and haven't seen any ill effects from it.

Hmm... My Cisco configuration is more complicated.... use Cisco- proprietary VLAN - isl:
interface FastEthernet0/1.1
encapsulation isl 10
ip address xx.xxx.xxx.xx 255.255.255.240 (Public IP)
interface FastEthernet0/1.22
encapsulation isl 22
ip address 10.1.10.1 255.255.255.224 (Private IP pro Star-OS)
So that de facto it isn't secondary IP.... BGP on of even configuration works ....
