2009-11-17Implements RFC 5004 - prefer older external routes.Ondrej Zajicek
2009-10-12Rename as_path_get_last/as_path_get_first to be consistent.Ondrej Zajicek
2009-08-27Some cleanups.Ondrej Zajicek
2009-08-25Fixes bug related to AS2->AS4 conversion.Ondrej Zajicek
2009-06-23Fixes bug in ORIGIN check.Ondrej Zajicek
2009-06-23Changes handling of AS_PATH_CONFED_* segments in AS_PATH.Ondrej Zajicek
Although standard says that if we receive AS_PATH_CONFED_* (and we are not a part of a confederation) segment, we should drop session, nobody does that and it is unwise to do that. Now we drop session just in case that peer ASN is in AS_PATH_CONFED_* segment (to detect peer that considers BIRD as a part of its confederation).
2009-04-29Allow 'third party' BGP updates for originated routes.Ondrej Zajicek
2009-04-29Fixes BGP IPv6 link local next hop handling.Ondrej Zajicek
When sending 'third party' BGP update, Bird used bogus link local addresses instead of addresses it received before.
2009-04-28Fixes handling of 'next hop self' and 'source address' configurationOndrej Zajicek
options.
2009-04-23Fixes BGPv6 bug - mandatory attributes weren't validated;Ondrej Zajicek
2009-04-23Fixes bug in BGPv6 causing crash by checking missing attributes.Ondrej Zajicek
2009-03-18Better handling of AS4 optional attribute errorsOndrej Zajicek
AS4 optional attribute errors were handled by session drop (according to BGP RFC). This patch implements error handling according to new BGP AS4 draft (*) - ignoring invalid AS4 optional attributes. (*) http://www.ietf.org/internet-drafts/draft-chen-rfc4893bis-02.txt
2009-02-27Better handling of too long attributesOndrej Zajicek
This patch extends the length for attributes from 1024 to 2048 (because both AS_PATH and AS4_PATH attributes take 2+4 B per AS). If there is not enough space for attributes, Bird skips that route group. Old behavior (skipping remaining attributes) leads to skipping required attributes and session drop.
2009-02-21Add format for BGP_AGGREGATOR attributeOndrej Zajicek
2008-12-19Major changes to BGPOndrej Zajicek
Fixes two race conditions causing crash of Bird, several unhandled cases during BGP initialization, and some other bugs. Also changes handling of startup delay to be more useful and implement reporting of last error in 'show protocols' command.

2008-10-26Bugfixes in MULIT_EXIT_DISC attribute handling.Ondrej Zajicek
- Old MED handling was completely different from behavior specified in RFCs - for example they havn't been propagated to neighboring areas. - Update tie-breaking according to RFC 4271. - Change default value for 'default bgp_med' configuration option according to RFC 4271.

2008-08-25The source address configuration in BGP added.Ondrej Filip
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
