Question 5/63
An OSPFv3 NSSA LSA is generated by an ASBR, describes routes to a destination outside the AS, and is advertised in an NSSA.
Options:
Options:
Correct Answer: A
Comprehensive and Detailed In-Depth Explanation:
* OSPFv3 (for IPv6) NSSA LSA (Type 7 LSA) is used in Not-So-Stubby Areas (NSSA).
* Generated by: An ASBR (Autonomous System Boundary Router) inside the NSSA area.
* Purpose: Advertises external routes (outside the AS) inside the NSSA.
* Conversion: When the LSA reaches an ABR, it gets converted to a Type 5 External LSA before being propagated to other OSPF areas.
* Why is this needed? NSSA areas allow some external route advertisements but do not permit normal Type 5 LSAs, so they use Type 7 LSAs instead.
