To reduce the size of OSPF Area 100, you configure the area with the no-summaries parameter. After
committing this configuration change, you notice that an OSPF router in a remote area is no longer receiving
Type 5 LSAs from an ASBR in Area 100.
Which statement is true in this scenario?
A.
The ASBR in Area 100 generates Type 5 LSAs, and they are blocked by the ABR.
B.
The ASBR in Area 100 generates Type 5 LSAs, and a virtual link is required for transport to other areas.
C.
The ASBR in Area 100 generates Type 5 LSAs, and they are transported to Type 7 LSAs.
D.
The ASBR in Area 100 generates Type 5 LSAs, and places them in its own database.
Explanation:
The no-summaries setting prevents the ABR from advertising summary routes into the NSSA.

Junos OS allows you to also restrict type 3 LSAs in NSSA areas using the no-summaries configuration option.
LSA Type 3: Summary LSA
LSA Type 4: Summary ASBR LSA
