Adam, This will not work between areas. Router-ID is not the IP address. While router in one are may have the ROUTE to what appears to be Router-ID in another area, it has that - a route. Router-ID is just a 32bit number in OSPF and NET in IS-IS. In both cases, the information is not present in another area. The solution for this problem is either loose next-hop or verbatim path.
