Both area zero and some area (say number 1) have ABSR where some routes are being injected into OSPF domain. I want to allow those external routes to propagate across the network, but not all of them. In particular I want area 0 and area 1 each maintain a separate default route. Also it is a requirement that some external routes that were injectet at area 1 ASBR were only available in that area, so I want to stop them from being propagated to AREA 0 and other areas.
Is this at all possible?
