This patch set corrects issues with IPv4 MPLS VPN (RF4364) SAFI support,
and adds support for IPv6 MPLS VPN (RFC4659), Encap SAFI and related
attribute and types (RFC5512, 5566). These changes are appropriate for
use of BGPd as a route reflector for these SAFIs. Import/export code
can be built on these core BGP mechanisms.
This update addresses comments raised on list (thanks to Vivek and
Donald for comments) as well as CI/regression testing.
The patch set can be viewed in four groups, but has only been fully
tested as a full set.
Group 1: 01 -> 09
This group includes minor/miscellaneous changes made as part
of the work on VPN and Encap SAFIs.
Group 2: 10 -> 25
This is the core VPN and Encap SAFI changes. They also include
configuration handlers, but not full show afi/safi changes.
Group 3: 24 -> 29
This patch set adds show commands in the form
show bgp <afi> <safi> ...
While the motivation for this work was supporting IPv4|6 VPN|Encap
SAFIs, we decided to support a generic afi/safi command form for
existing commands as well for overall command consistency.
Old/existing commands remain available for compatibility. The patches
are submitted in a way to facilitate removal of the old/non-generic
from of commands if/when the decision is made to remove them.
Group 4: 30
This change removes HAVE_IPV6 conditionals from the above as well as
the rest of bgpd
G. Paul Ziemba is the primary author of these changes, with me doing
some additional changes. This set replaces the set previously submitted
by Paul. The patch breakdown is based on (much appreciated) review and
changes done by David Lamparter.
