Edge routers (e1, and e2) are dual multi-homed with 3 providers ( 2 providers are on e1 and another 1 provider is on e2). Both receive full+default announcements from the providers
Edge routers are advertising only a default route to the core routers (c1 and c2)
Edge routers originate a default to core routers ( c1 and c2) if and only if they have a default route in their routing table
From the reading this "conditional announcement" can be achieved using the "neighbor x.x.x.x default-originate route-map rmap" command in router config mode. If at least one prefix in the route-map ( here: rmap) is matched in the local routing table, a default will be originated.
Can you specify the route-map to match on the default prefix as follows?:
This is actually a pretty cool feature, i didn't even know it existed until I was looking for a solution to advertise a subnet (prefix in BGP talk), only if a certain condition existed. This is exactly what conditional advertisements does
