Type 5 LSA are created by ASBR's that have external routes injected into OSPF such as redistributed routes.

Type 7  LSA are created by ASBR's that are part of a NSSA or Totally NSSA. They are converted into LSA type 5 when they are injected into another area.

Good... did you mean total NSSA or toally Stubby in above?

Sorry I meant only NSSA.

Just wondering, Is there anything as totally NSSA.. not getting much handle on these concepts.
Soulja53 6F 75 6C 6A 61 Commented:
No, there is totally stubby, but not a totally NSSA. That would contradict itself, because it's saying it Not So Stubby.

My comment that had that in it was a typo of trying to multitask at work and answer the question.
