I don't think LSA's are considered Functionally equivalent with different or zero forwarding address. So need to consider both LSA's in route calc.

In RFC 3101 (NSSA option), section 2.5.6 (e) for calculating External LSA states; (e) If the current LSA is functionally the same as an installed LSA (i.e., same destination, cost and non-zero forwarding address) then apply the following priorities in deciding which LSA is preferred: 1. A Type-7 LSA with the P-bit set. 2. A Type-5 LSA. 3. The LSA with the higher router ID. [NSSA] My doubt is: If the both LSAs have zero FA or different FA then should the above preference rule be skipped and both LSAs be considered for SPF?
