JN0-346 · Question #45
Which two statements are true about OSPF not-so-stubby areas? (Choose two.)
The correct answer is A. The ASBR originates Type 7 LSA a for redistributed external routes. D. Type 7 LSAs are translated by the ABR into Type 5 LSAs. Redistribution into an NSSA area creates a special type of link-state advertisement (LSA) known as type 7, which can only exist in an NSSA area. An NSSA autonomous system boundary router (ASBR) generates this LSA and an NSSA area border router (ABR) translates it into a type5…

Explanation
Redistribution into an NSSA area creates a special type of link-state advertisement (LSA) known as type 7, which can only exist in an NSSA area. An NSSA autonomous system boundary router (ASBR) generates this LSA and an NSSA area border router (ABR) translates it into a type5 LSA, which gets propagated into the OSPF domain.
