2019-07-09OSPF: Fix handling of external routes on graceful restartOndrej Zajicek (work)
We need to flush learned external LSAs a bit later than other LSAs (after first feed after end of the graceful restart) to avoid flap of external routes.
2019-06-30OSPF: Support for graceful restartOndrej Zajicek (work)
Implement OSPFv2 (RFC 3623) and OSPFv3 (RFC 5187) graceful restart, for both restarting and helper sides. Graceful restart is initiated by 'graceful down' command.
2019-02-13OSPF: Basic support for DN-bit handling (RFC 4576)Ondrej Zajicek (work)
External LSAs originated by OSPF routers with VPN-PE behavior enabled are marked by DN flag and they are ignored by other OSPF routers with VPN-PE enabled.
2018-05-30Nest: Removing separate tmpa from route propagationJan Maria Matejka
This is a fundamental change of an original (1999) concept of route processing inside BIRD. During import/export, there was a temporary ea_list created which was to be used instead of the another one inside the route itself. This led to some confusion, quirks, and strange filter code that handled extended route attributes. Dropping it now. The protocol interface has changed in an uniform way -- the `struct ea_list *attrs` argument has been removed from store_tmp_attrs(), import_control(), rt_notify() and get_route_info().
2017-12-07OSPF: Update to new timersOndrej Zajicek (work)
Note that recurrent timers are currently limited to ~1 hour.
2016-12-22Merged multipath and single-path data structures.Jan Moskyto Matejka
Dropped struct mpnh and mpnh_*() Now struct nexthop exists, nexthop_*(), and also included struct nexthop into struct rta. Also converted RTD_DEVICE and RTD_ROUTER to RTD_UNICAST. If it is needed to distinguish between these two cases, RTD_DEVICE is equivalent to IPA_ZERO(a->nh.gw), RTD_ROUTER is then IPA_NONZERO(a->nh.gw). From now on, we also explicitely want C99 compatible compiler. We assume that this 20-year norm should be known almost everywhere.

2015-11-05Initial commit on integrated BIRDOndrej Zajicek (work)
New data types net_addr and variants (in lib/net.h) describing network addresses (prefix/pxlen). Modifications of FIB structures to handle these data types and changing everything to use these data types instead of prefix/pxlen pairs where possible. The commit is WiP, some protocols are not yet updated (BGP, Kernel), and the code contains some temporary scaffolding. Comments are welcome.

2010-05-02OSPF: most of summary LSA orig./flush logic rewritten.Ondrej Zajicek
Fixes many bugs in the old code and makes it much cleaner.
2010-04-24Fixes and enhancements in 'show ospf state' command.Ondrej Zajicek
Now it shows a distance, option to change showing reachable/all network nodes and better handling of AS-external LSAs in multiple areas. The command 'show ospf topology' was changed to not show stubnets in both OSPFv2 and OSPFv3 (previously it displayed stubnets in OSPFv2).

2005-02-13Many bugfixes in routing table calculation and summary LSA origination.Ondrej Filip
2004-07-15Huge OSPF database redesign. Since now, all LSAs of all areasOndrej Filip
are in single database. This avoids duplication of external LSAs and fixes bug in external LSA distribution.
2004-06-25A lot of changes:Ondrej Filip
- metric is 3 byte long now - summary lsa originating - more OSPF areas possible - virtual links - better E1/E2 routes handling - some bug fixes.. I have to do: - md5 auth (last mandatory item from rfc2328) - !!!!DEBUG!!!!! (mainly virtual link system has probably a lot of bugs) - 2328 appendig E

2004-06-01Patch from Andreas Steinmetz <ast@domdv.de>Ondrej Filip
2004-05-31The code was broken for external /29 to /32 routes. Assuming that youMartin Mares
have one machine publishing a route to 10.1.1.3/32 and another one publishing a route to 10.1.1.4/32. If the first machine went down the route to 10.1.1.4/32 was wrongly killed by the old code, leading either to missing routes or worse to bug()s like "Router parent does not have next hop" or just segfaults. The patch fixes this but in the long term a redesign is required here. Note that the patch doesn't worse the situation, instead it prevents the problems stated. The redesign is required to handle multiple routes to small subnets properly. (by Andreas) Feela, I think that this is at least a good temporary fix, but it's of course up to you to decide.
