Why are you trying to setup zebra?

If you just want the Linux box to operate as a simple router between two
networks, remove zebra, activate forwarding and masquerading and you are
done.
Forwarding:
sysctl -w net.ipv4.ip_forward=1

The needed static routes are usually set automatically as soon as the
interfaces are initialized.

I'm trying to setup zebra because I have 3 subnets with 3 linux boxes
configured as router with zebra and ospfd. Maybe if I activate Masquerading,
it would work.
Cheers,
