Nick,
I think you missed Thille's question. He needs multiple level 2 (area routers), unless he makes use of an area at another site which would not be wise becuase of performance and reliability.
Thille, we have the same problem and now have 3 decnet area's used by us (Honeywell ATSD eng.) and a fourth used by other groups in the plant. We have seperate AGS+s acting as the area routers. If you have a small number of nodes in a second area, you might get by with using an IGS+ or even a VAX as the area router. There are some nasty's to watch out for such as packets being bounced between the highest priority routers. If you're interested in more, let me know.
