ospfd: Fix maxage/flush to not try flood twice, remember maxages for longer
2006-05-30 Paul Jakma <paul.jakma@sun.com>
* (general) Fix confusion around MaxAge-ing and problem with
high-latency networks. Analysis and suggested fixes by
Phillip Spagnolo, in [quagga-dev 4132], on which this commit
expands slightly.
* ospf_flood.{c,h}: (ospf_lsa_flush) new function.
Scope-general form of existing flush functions, essentially
the dormant ospf_maxage_flood() but without the ambiguity of
whether it is responsible for flooding.
* ospf_lsa.c: (ospf_lsa_maxage) Role minimised to simply setup
LSA on the Maxage list and schedule removal - no more.
ospf_lsa_flush* being the primary way to kick-off flushes
of LSAs.
Don't hardcode the remover-timer value, which was too
short for very high-latency networks.
(ospf_maxage_lsa_remover) Just do what needs to be done to
remove maxage LSAs from the maxage list, remove the call
to ospf_flood_through().
Don't hardcode remove-timer value.
(ospf_lsa_{install,flush_schedule}) ospf_lsa_flush is the correct
entrypoint to flushing maxaged LSAs.
(lsa_header_set) Use a define for the initial age, useful for
testing.
* ospf_opaque.c: (ospf_opaque_lsa_refresh) ditto.
(ospf_opaque_lsa_flush_schedule) ditto.
* ospfd.h: ({struct ospf,ospf_new}) Add maxage_delay parameter,
interval to wait before running the maxage_remover. Supply a
suitable default.
Add a define for OSPF_LSA_INITIAL_AGE, see lsa_header_set().
