pls help on Zebra !!

Are some ppl here familiar with ZEBRA (router software package for linux)?

I'm trying to configure OSPF over an interface but I don't want to bother about technical IP addys.
I'd like to config ZEBRA in unnumbered mode.

Any help will be appriciated, thanx.


Info: Unnumbered
2 routers running OSPF in P2P share the same LAN. The OSPF protocol sends updates & hello packets with a multicast destination @ (224.0.0.1). The protocol should not take care of the IP source, but by default a filter is set on it.
If a rcv frame does not belong to the same ip subnet it is dropped.
The unnumebred mode allow to configure no IPs on interface & to remove the filter.
