I have a question,
I'm busy implementing pppoe servers at all my highsites.
The clients connects to the pppoe server and gets a public ip address from the radius server.
Ospf then redistributes that public address, now my issue is, not really a issue but something that bugs me.
I don't want the edge router to recieve ospf routers that is private addresses, only the /32's that is give to the clients. then I dont wan't the access routers to recieve any routes from the edge because their default routes point the the edge router.
I played around with the route filters but found that if i discard lets say 10.0.0.0/8 on the ospf-in if will only discard that prefix and no other routes under that subnet for example 10.1.1.0/30.
Same for the /32 's it will only accept a /24 prefix but not the /32's that make up that subnet.
Is there any way to work around the problem using route filters or maybe bgp?
