Ondrej Zajicek dd91e46765 Differentiate between error delay and connect/reconnect delay.
The difference is here to reject incoming connections in the
first case.

Ondrej Zajicek 4827b69ff4 Fixes BGP IPv6 link local next hop handling.
When sending 'third party' BGP update, Bird used bogus link local
addresses instead of addresses it received before.

Add 'capabilities' option, change default behavior to advertise ipv4,
add some checks and ignore incoming capabilities when capabilities
are disabled.

Ondrej Zajicek 11b32d9117 Major changes to BGP
Fixes two race conditions causing crash of Bird, several unhandled

handling of startup delay to be more useful and implement
reporting of last error in 'show protocols' command.

Ondrej Zajicek 11cb620266 Implementation of 4B ASN support for BGP 2008-10-26 22:36:08 +01:00
Martin Mares 11d4474c17 Better selection of link-local NLRI addresses, at least for our own
address. Need to do it better for the other neighbors -- the current
solution works only if they use the standard 64+64 global addresses
and the interface identifier in lower 64 bits is the same as for the
link-scope addresses.
2003-02-22 22:47:45 +00:00
Martin Mares 5e88d73025 BGP now reports originating AS and origin type in get_route_info(). 2000-05-19 11:01:41 +00:00
Martin Mares 93d6bf38a6 The bgp_list is gone. Incomming connections are now handled in a much
more straightforward manner by scanning the active configuration for
matching protocols.
2000-05-08 13:26:30 +00:00
Martin Mares cf3d6470d7 IPv6 BGP support finished. Also simplified the BGP stuff a bit. 2000-05-04 20:02:56 +00:00

Allow setting of address of the local end of the TCP connection.

Several bug fixes.
2000-04-21 13:01:28 +00:00
Martin Mares 2a9e064d7b If no NLRI's are present in an UPDATE message, parse the attributes, but
don't check presence of mandatory attributes. [draft-09]
2000-04-21 12:25:35 +00:00
Martin Mares bd2d8190dd Honor standard communities (no_export, no_advertise, no_export_subconfed)
when exporting routes.
2000-04-17 13:13:08 +00:00
Martin Mares 56a2bed46b Don't import/export MED and LOCAL_PREF on external links.
Added real comparison of BGP routes (inspired by the Cisco one).
Default local preference and default MED are now settable.
Defined filter keywords for all BGP attributes we know.

Martin Mares c0668f3696 Created nest/a-path.c and a-set.c which should contain general operations
on AS paths and community sets.

Moved as_path_prepend() there.

Pavel, please move the other functions as well.

Calculate next_hop properly based on the local address we get from the
neighbor entry.

Martin Mares ef2c708dfa More BGP progress...
For Pavel: You can use bgp_path_prepend() for prepending AS numbers to AS paths.
