What is your addressing scheme? The next hop IP address needs to be known by the router, then ARP is used to determine the MAC address to which the packet is to be forwarded. If you are using a class C address with a 30 bit mask, there are only two host addresses per subnet. One of those belongs to the local router and the belongs to the remote router. The local router is able to determine what address is at the remote end by the process of elimination. If you are using, for example, a class C address with a 24 bit mask, the router doesn't know which IP address is the next hop as there are 253 possibilities. In this case, use the remote router's address in your route statement.
