Re: preferring OSPF inter-area compared to intra-area

This filters the RIB (routing table), not the OSPF decision process. By the time you apply this OSPF has already chosen the intra area route over the inter area one, so all you can do is permit or deny the intra area one.

The only way to really accomplish this is to make the two route types equal. If you were to change the inter area route to intra area with something like a virtual link or tunnel then you can modify which path is preferred.
