Well, subnet is the only thing that is important for OSPF, so I am not
sure if proxy arp will work. But I think hopefully it should do the
trick, because IP 10.0.0.2 is only for management, proxy arp is
transparent to both router1 and router2. It should work as is. However
I have not tested it myself, it is just an assumption.
