Hello guys,
I try to setup an openbgpd setup involving multipath configuration ...with no
success.
My bgpd.conf is like that
------------------------------------------------------------------------------------------------------------------------
prefix-set privnetworks {
10.55.0.0/16
10.60.0.0/16
172.16.0.0/12
}
log updates
network 10.240.0.0/16
group "eBGP" {
remote-as $AS1
neighbor $GW01 {
descr "bgp#1"
announce IPv4 unicast
announce add-path recv yes
set localpref 110
}
neighbor $GW02 {
descr "bgp#2"
announce IPv4 unicast
announce add-path recv yes
set localpref 110
}
}
match from any community GRACEFUL_SHUTDOWN set { localpref 0 }
deny quick from group eBGP prefix 0.0.0.0/0

Show me two routes one marked with multipath
But in fib I see only one route
#bgpctl sh fib 172.18.180.0/24
flags: B = BGP, C = Connected, S = Static
N = BGP Nexthop reachable via this route
r = reject route, b = blackhole route
flags prio destination gateway
B 48 172.18.180.0/24 10.0.1.241
Confirmed by route
#route -n get 172.18.180.0/24
route to: 172.18.180.0
destination: 172.18.180.0
mask: 255.255.255.0
gateway: 10.0.1.241
interface: sec7130
if address: 10.0.1.242
priority: 48 (bgp)
flags: <UP,GATEWAY,DONE>
label: PRIVNET
use mtu expire
0 0 0
sockaddrs: <DST,GATEWAY,NETMASK,IFP,IFA,BRD,LABEL>
Multipath is enabled
# sysctl net.inet.ip.multipath
net.inet.ip.multipath=1
and static routes with -mpath option are setup correctly
What I miss here ??
