This patch contains the following:
1. Addition of IPv4 SAFI_MULTICAST BGP routes into the BGP Multicast RIB.
2. Deletion of IPv4 SAFI_MULTICAST BGP routes from the BGP Multicast RIB.

routes. Use a growable buffer (bgp_nexthop_buf) to collect nexthops
that are included in the announcement. Use the BGP_INFO_MULTIPATH_CHG
flag to trigger zebra announcement so zebra will be updated if the
multipath set changes. Display all multipath nexthops in
'debug bgp zebra' output.
* bgpd/bgp_main.c
* bgp_exit(): Free bgp_nexthop_buf when exiting
* bgpd/bgp_route.c
* bgp_process_rsclient(): Clear BGP_INFO_MULTIPATH_CHG after processing
* bgp_process_main(): Check BGP_INFO_MULTIPATH_CHG to trigger zebra
announcement and clear aftr processing
* bgpd/bgp_zebra.c
* bgp_nexthop_buf: Growable buffer used to collect nexthops for zebra
announcement
* bgp_zebra_announce(): Grow bgp_nexthop_buf if needed. Include
multipath count in zebra announcement and add all nexthops to
bgp_nexthop_buf. Pass bgp_nexthop_buf data to zebra announcement.
Added nexthops to debug output.
* bgp_zebra_init(): Initialize bgp_nexthop_buf at startup
* bgpd/bgp_zebra.h
* BGP_NEXTHOP_BUF_SIZE: Default initial bgp_nexthop_buf size has room
for 8 nexthops

There is support to configure this for each (AFI,SAFI), but
currently this configuration is only present for IPv4 unicast:
maximum-paths [ibgp] <1-255>
no maximum-paths [ibgp] [<1-255>]
* bgpd/Makefile.am
* Add bgp_mpath.h and bgp_mpath.c to build
* bgpd/bgp_mpath.h
* New file for bgp multipath declarations
* define BGP_DEFAULT_MAXPATHS
* bgpd/bgp_mpath.c
* bgp_maximum_paths_set(): Configure maximum paths for the given
afi, safi and bgp instance
* bgp_maximum_paths_unset(): Return maximum paths configuration to
the default setting for the given afi, safi and bgp instance
* bgpd/bgp_vty.c
* Define command strings for above CLI
* bgp_config_write_maxpaths(): Outputs configuration for the given
afi, safi and bgp instance
* Install command elements for IPv4 unicast
* bgpd/bgp_zebra.h
* bgp_config_write_maxpaths(): External declaration
* bgpd/bgpd.c
* bgp_create(): Initialize bgp instance to default maximum paths setting
* bgp_config_write_family(): Output maximum paths configuration
for the given address family
* bgp_config_write(): Output maximum paths configuration for
IPv4 unicast address family
* bgpd/bgpd.h
* struct bgp: Add storage for maximum paths configuration for
each afi, safi

* (global) The great bgpd extern and static'ification.
* bgp_routemap.c: remove unused ROUTE_MATCH_ASPATH_OLD code
(route_set_metric_compile) fix u_int32_t to ULONG_MAX comparison
warnings.
* bgp_route.h: (bgp_process, bgp_withdraw, bgp_update) export these
used by various files which had their own private declarations,
in the case of mplsvpn - incorrect.
|
|
* bgp_fsm.h: Add extern qualifier to exported functions
* bgp_nexthop.c: add static to nexthop specific globals
* *.h: Add guard defines
|
|
* (global) more const'ification and fixups of types to clean up code.
* bgp_mplsvpn.{c,h}: (str2tag) fix abuse. Still not perfect,
should use something like the VTY_GET_INTEGER macro, but without
the vty_out bits..
* bgp_routemap.c: (set_aggregator_as) use VTY_GET_INTEGER_RANGE
(no_set_aggregator_as) ditto.
* bgpd.c: (peer_uptime) fix unlikely bug, where no buffer is
returned, add comments about troublesome return value.
