Hi All,
I have a doubt related to Path preference rule when there are LSA with
different FA.
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?
Thanks and Regards
Abhishek
