the metric to the highest and least preferred possible value else no routes
are redistributed. OK norby@

so there is no need to loop over the nexthops and we no longer need to
pass the rt_nexthop to the summary LSA generation (a flag is enough).

aware. Both the SPF and RIB trees need additional structures to store the
multiple nexthops to the destination but only the first active nexthop is
passed to the parent process and used for routing. This is the next thing
that needs to be modified. Tested and OK pyr@

ASBR router ID. Using the avertising router for this only works for intra-
area routes but fails horribly for inter-area ones. Luckily RIB router entries
use the router ID as prefix so just use that instead -- this simplifies the
code nicly. Figured out the hardway by pyr@. Tested and OK pyr@

Inter-area routes are already comming from the backbone so readding them
is wrong.

Change kroute.c code so that it correctly tracks multipath routes.
Route redistribution is way more complex in a mulitpath environment.
It is not possible to redistribute multiple pathes and only a part of the
multipath routes may be redistributable. So a route is redistributed as soon
as one of the multipath routes is redistributable.
Tested and OK norby@ and pyr@ -- at least we see no regression

the router LSA so that the change propagates instantly. Call orig_rtr_lsa()
in merge_config() if a interface in an area changes. Do it as late as possible
to reduce the amount of updates generated by a config reload.

"router" needs to be added before "router-dead-time".

switch to "stub router yes" if the forwarding sysctl is set to something
differently than 1. This can be overruled by a later "stub router no"
in ospfd.conf. More work is needed here.
OK norby@
|
|
Also modify the fib-update block a bit because "fib-update no" implies
"stub router yes".
OK norby@
|
|
This allows ospfd to announce networks without the need to transit traffic.
stub router is enabled if the fib is not coupled, net.inet.ip.forwarding is
not 1 or if the stub router global config option is set to yes.

to fill the full buffer the perfect job for stncpy().

If no metric was specified for it to DEFAULT_REDIST_METRIC. While this was
checked for the simple case it was not done if only a metric type was
specified. OK pyr@
|

so don't unref before calling kroute_remove() or we end up with wrong
reference counts.
|

for stuff like RTM_IFINFO or RTM_IFANNOUNCE. So move check to a save location.
Always check rtm_type before accessing some random value inside the route
message.

and scan all available areas in that case -- the only case when this may
happen is for self announced AS-ext LSA. This solves a crash when
redistributed routes were removed shortly after startup.

all other routers will drop the session immediatly instead of waiting for
the timeout that is normaly 40 sec. This reduces fail-over time massivly
and does not hurt anymore since we are now able to reload the configuration
on the fly. OK norby@ pyr@

after fixing many use-after-free errors a couple of days ago.
Most cases -- adding/removing of interfaces, adding/removing of areas --
seem to work. Still merge_config() is a behemoth of a function and some
edge cases may not be covered correctly (yet).

takes care that redistribution is correct after reload. OK norby@ pyr@

rde_asext_put(). Just try to remove the as-ext LSA, if the prefix is
announced as stub net LSA lsa_find() will fail later and nothing will
happen. OK norby@ pyr@

the actual LS DB entry is removed. In particular a neighbor may be removed
at any time -- we were lucky because we kept down neighbors around for
another 24h. Reload support unhided this problem again. Just copy the
needed info into the vertex. Pointing to the area is save as the vertex is
part of the area itself and removed when the area is removed.
