Need help getting NSSA ABR to flood default from NSSA ASBR
I am having trouble advertising a default route from an NSSA ASBR to the ABR, and then subsequently getting the NSSA ABR to propagate that default route to the OSPF domain. The NSSA is connect to area 0 w/ a virtual link. I have tried different versions of routers/code to no avail. The farthest I have been able to get is configuring area x nssa default-information originate along w/ a static default route on the NSSA ASBR. Sometimes the NSSA ABR will show an N2 in the routing table. It would appear the the P-bit is not set because the default route never gets propagated. I'm able to get the external default route propagated if I connect it to an ABR directly.
Re: Need help getting NSSA ABR to flood default from NSSA ASBR
Have you also included the "default-information-originate" in the area nssa command of the NSSA ABR, as well as the NSSA ASBR?
Also, I'm not sure why the ABR will only show the N2 sometimes. Is the route also going down in the ASBR at the same time it goes down in the ABR? Does the Type 7 LSA come and go from the OSPF database?
