Can you have a OSPF network, with several routers sending the default routes, but have one primary default route running type 2, and the rest type1. So if the type 2 default route goes down, the network will use the type 1 default routes to route traffic out based on cost, but if that type 2 comes back up, everything will switch to it?
So the question is, can you have both type1 and type2 default routes in one OSPF area?
