BGP: Handle case where capabilites are not used

If peer does not announce capabilities at all, or when we have
capabilities disabled, handle that as implicit IPv4 unicast.

BGP: Cleanup channels when going down

When going up, uncleaned old channel state may trigger unexpected
conditions crashing bird.

BGP: Extend 'next hop keep' and 'next hop self' options

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...

BGP: implement Adj-RIB-In

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...

Terminology cleanup: The import_control hook is now called preexport.

Once upon a time, far far away, there were the old Bird developers
discussing what direction of route flow shall be called import and
export. They decided to say "import to protocol" and "export to table"...

863ecfc7 11/20/2018 04:45 PM Ondrej Zajicek (work)

The MRT protocol

The new MRT protocol is responsible for periodic RIB table dumps in the
MRT format (RFC 6396). Also the existing code for BGP4MP MRT dumps is
refactored and splitted between BGP to MRT protocols, will be more
integrated into MRT in the future....

Nest: Removing separate tmpa from route propagation

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...

plan is to switch from the old inteface to the new interface, then clean
it up.

BGP: Shutdown communication (RFC 8203)

The patch implements BGP Administrative Shutdown Communication (RFC 8203)
allowing BGP operators to pass messages related to BGP session
administrative shutdown/restart. It handles both transmit and receive of
shutdown messages. Messages are logged and may be displayed by show...

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,...

1e37e35c 03/22/2017 05:16 PM Ondrej Zajicek (work)

BGP: Support for MPLS labels and VPN SAFI

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.

Removes phantom protocol from the pipe design.

could completely eliminate the need for the phantom protocol instance

Better handling of well-known communities.

to process these attributes after, which does not allow to send route
with such community) and just for routes received from other BGP
