Subject: [zebra 16823] [PATCH] Bugfix and new feature in Opaque-LSA
handling.

----- * ----- * ----- * ----- * ----- * ----- * ----- * ----- * ----- * -----
Changes 2002.12.20

1. Bug fixes

  1.1 When an opaque LSA is being removed from (or added to) the LSDB,
      it does not mean a change in network topology. Therefore, SPF
      recalculation should not be triggered in that case.
      There was an assertion failure problem "assert (rn && rn->info)"
      inside the function "ospf_ase_incremental_update()", because
      the upper function "ospf_lsa_maxage_walker_remover()" called it
      when a type-11 opaque LSA is removed due to MaxAge.

  1.2 Type-9 LSA is defined to have "link-local" flooding scope.
      In the Database exchange procedure with a new neighbor, a type-9
      LSA was added in the database summary of a DD message, even if
      the link is different from the one that have bound to.

2. Feature enhancements

  2.1 Though a "wildcard" concept to handle type-9/10/11 LSAs altogether
      has introduced about a year ago, it was only a symbol definition
      and actual handling mechanism was not implemented. Now it works.
