This is a major change of how the filters are interpreted. If everything
works how it should, it should not affect you unless you are hacking the
filters themselves.
Anyway, this change should make a huge improvement in the filter performance
as previous benchmarks showed that our major problem lies in the
recursion itself.
There are also some changes in nest and protocols, related mostly to
spreading const declarations throughout the whole BIRD and also to
refactored dynamic attribute definitions. The need of these came up
during the whole work and it is too difficult to split out these
not-so-related changes.

Extend 'next hop keep' and 'next hop self' options to have boolean values
(enabled / disabled) and also values 'ibgp'/ 'ebgp' to restrict it to
routes received from IBGP / EBGP. This allows to have it enabled by
default in some cases, matches features of other implementations, and
allows to handle some strange cases like EBGP border router with 'next
hop self' also doing IBGP route reflecting.
Change default of 'next hop keep' to enabled for route servers, and
'ibgp' for route reflectors.
Update documentation for these options.

The patch implements optional internal import table to a channel and
hooks it to BGP so it can be used as Adj-RIB-In. When enabled, all
received (pre-filtered) routes are stored there and import filters can
be re-evaluated without explicit route refresh. An import table can be
examined using e.g. 'show route import table bgp1.ipv4'.
|
|
The patch implements long-lived graceful restart for BGP, namely
draft-uttaro-idr-bgp-persistence-03.
|
|
|
|
This supersedes the EAP_* constants.
|
|
|
|
The option allows to specify that some cease subcodes should
disable the protocol when received.
|
|
To comply with RFC 8212 requirements.
|
|
Multiple definitions of same channels are forbidden, but inherited
channel can be redefined. In such case channel options are merged.
|

ECMP is not enabled on BSD, where it is not supported by BIRD.
|
|
|
|
Which, in contrast to SAFI 128, does not use MPLS labels.
|
|
|
|
Covers IPv4/VPNv4 routes with IPv6 next hop (RFC 5549), IPv6 routes with
IPv4 next hop (RFC 4798) and VPNv6 routes with IPv4 next hop (RFC 4659).
Unfortunately it also makes next hop hooks more messy.
Each BGP channel now could have two IGP tables, one for IPv4 next hops,
the other for IPv6 next hops.
|
|
Basic support for SAFI 4 and 128 (MPLS labeled IP and VPN) for IPv4 and
IPv6. Should work for route reflector, but does not properly handle
originating routes with next hop self.
Based on patches from Jan Matejka.

Adds option 'allow bgp_local_pref' to override the usual restriction of
LOCAL_PREF on eBGP sessions.
Thanks to Lennert Buytenhek for the patch.

Mostly capability signalling
|
|
|
|
|
|
Integrated and extensible BGP with generalized AFI handling,
support for IPv4+IPv6 AFI and unicast+multicast SAFI.
|
|
|
|
Add support for large communities (draft-ietf-idr-large-community),
96bit alternative to RFC 1997 communities.
Thanks to Matt Griswold for the original patch.

Add code for manipulation with TCP-MD5 keys in the IPsec SA/SP database
at FreeBSD systems. Now, BGP MD5 authentication (RFC 2385) keys are
handled automatically on both Linux and FreeBSD.
Based on patches from Pavel Tvrdik.
|
|
The patch adds support for channels, structures connecting protocols and
tables and handling most interactions between them. The documentation is
missing yet.
|
|
Implements draft-ietf-idr-bgp-extended-messages-10, for now
undocumented and with temporary private capability number.
|
|
Also update log message for error-triggered startup delay.
|
|
Permit specifying neighbor address, AS number and port independently.
Add 'interface' parameter for specifying interface for link-local
sessions independently.
Thanks to Alexander V. Chernikov for the original patch.
|
|
Make proto_config_new() use this info instead of supplied size.
Thanks to Alexander V. Chernikov for the patch.
|
|
Configurable fast shutdown of a BGP session when an interface loses link.
|
|
|
|
Thanks to João Taveira Araújo for the original patch.
|
|
Thanks to Frederik Kriewitz for the patch.
|
|
Also significant core protocol state changes needed for that,
global graceful restart recovery state and kernel proto support
for recovery.
|
|
|
|
This is more consistent with common usage and also with the behavior of
other implementations (Cisco, Juniper).
Also changes the default for gw mode to be based solely on
direct/multihop.

Supports OSPF and BGP and also statically configured sessions.
|
|
Similar to allowas-in option on other routers.
|
|
This option allows to keep the received next hop even in cases when
the route is sent to an interface with a different subnet.
|
|
Allows to send and receive multiple routes for one network by one BGP
session. Also contains necessary core changes to support this (routing
tables accepting several routes for one network from one protocol).
It needs some more cleanup before merging to the master branch.
