I have a problem with a small NSSA Area with 2 ABRs and 2 ASBRs which advertising the same external routes. Both ASBRs are connected to both ABRs. The ABR with the higher ID injects both paths as "N2" in his routing table. But the ABR with the lower ID injects only one path (as "E2") in his routing table!!
Is this an normal behvior, that:
- the ABR with the higer ID generates only
one Type-5 LSA out of the 2 Type-7 LSAs
The "show ip ospf database
nssa-xternal" shows both entries.
The "show ip ospf database external" shows
only one entry
- the ABR with the lower ID "trust" the one
Type-5 LSA more then the both Type-7 LSAs
in the database
Thanks for your help
