Gib,
Do you get the same number of routing entries from the router demand polls from
either NetView?
Sounds like a good scenario for an "iptrace" from each of the NetView servers to
the router during the demand polls.

Gib, I'm afraid I was in a hurry and didn't read your original post close
enough. I was thinking of the difference between a production ROUTER with
large tables and a test ROUTER with small tables. I see now that you are
looking at the same router (same tables) with two different NetViews.
Anybody with a clear head have any suggestions?
