How to use ospfd and zebra on virtual interfaces?

Hi all,
I am new to the world of networking and unix.
Thanks to all for having this group.

I wanted to know how to use ospfd and zebra.
say i have 3 virtual interfaces along with eth0 on one linux box and i
need to route between them. Can anyone give me an example of how to do
it.

Thanks in advance
