How to configure OSPF NSSA (Not So Stubby) Area

Hello Ali

Take a look at this response here:

OSPF Non-Broadcast Network Type over Frame-Relay

Hello Ali First of all, having 60 OSPF routers in a single broadcast domain will cause you problems. And if I understand correctly, you have a hub and spoke topology, so all of the remote routers are listening to broadcast traffic on this single subnet over their WAN connections. So you’re using up bandwidth unnecessarily, and you are also causing the routers to look at broadcasts that do not belong to them, so they continually discard them. The best way to resolve this issue is not to choos…

I hope this has been helpful!
