RD> Router A and B are connected via a common ethernet segment 1.
RD> Router A uses 10.10.10.1/30, and Router B uses 10.10.10.2/30.
RD> Router B also has another subnet configured for ethernet
RD> segment 1; 172.16.16.0/24.

RD> When I setup a situation like the above, with Router B
RD> advertising the 172.16.16.0/24 to router A, router A sees a
RD> next hop of 10.10.10.2.  This is not good since packets from
RD> A going to the 172.16.16 subnet get sent to Router B, which
RD> then ARPs the desitnation, instead of just being ARPed by
RD> router A.

Is this what you're trying to do:

	route-map <foo>
	 match <whatever>
	 set ip next-hop <something>

?
