[Lsr] some doubts about RFC3101

[meicong <[e-mail]>]

Hi All,
Could you please provide clarification for following section 2.5.(3) in rfc3101.

          If the forwarding address is non-zero look up the forwarding
          address in the routing table.  For a Type-5 LSA the matching
          routing table entry must specify an intra-area or inter-area
          path through a Type-5 capable area.  For a Type-7 LSA the
          matching routing table entry must specify an intra-area path
          through the LSA's originating NSSA.  If no such path exists
          then do nothing with this LSA and consider the next in the
          list.
          [NSSA]

In the section, the matching routing table entry of the forwarding address is limited("an intra-area or inter-area path through a Type-5 capable area" or "an intra-area path through the LSA's originating NSSA").
If the best matching routing table entry for the forwarding address does not match the limited, the secondory best matching routing table entry should be find or not?

e.g., the forwarding address of a Type-5 LSA is 128.185.1.1,
and there are two routing table entry int the routing table on the abr,
(128.185.1.0, 0xffffff00) intra-area route of the NSSA area,
(128.185.0.0, 0xffff0000) intra-area route of the normal area(Type-5 capable area),
The path of the forwarding address should be consider as exist or not?
