The 60ish routers in an OSPF network is not really the issue. If you have that many routers in a broadcast domain, using smaller subnets isn't likely to make much difference. Although, NBMA can reduce the neighbor list size. You will most likely still have the same routing table except all traffic would go through the hub router. Frankly, you will most likely be better off with a vlan per site and just trunk those back to the MT and let it talk with one device that way (one device per vlan, I mean). It's hard to say for sure without a bit more detail on how you have this set up, but that's my initial take-away. -- Butch Evans Training and Support for WISPs 702-537-0979 http://store.wispgear.net/ http://www.butchevans.com/ _______________________________________________ Mikrotik mailing list [email protected] http://mail.butchevans.com/mailman/listinfo/mikrotik Visit http://blog.butchevans.com/ for tutorials related to Mikrotik RouterOS
