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 --- bgpd/bgpd.h | 6 ++++++ 1 file changed, 6 insertions(+) (limited to 'bgpd/bgpd.h') diff --git a/bgpd/bgpd.h b/bgpd/bgpd.h index 4da19e71..bd03f653 100644 --- a/bgpd/bgpd.h +++ b/bgpd/bgpd.h @@ -162,6 +162,12 @@ struct bgp /* BGP graceful restart */ u_int32_t restart_time; u_int32_t stalepath_time; + + /* Maximum-paths configuration */ + struct bgp_maxpaths_cfg { + u_int16_t maxpaths_ebgp; + u_int16_t maxpaths_ibgp; + } maxpaths[AFI_MAX][SAFI_MAX]; }; /* BGP peer-group support. */ -- cgit v1.2.1
