Hey All,
Im trying to configure the folowing topology:
lns box (multiple ppp devices that connect and disconnect) -> multiple
default gw (gw load balance)
the issue is if one of the multiple gw crash I got routing blackhole...
Im trying to configurefd to delete dead peers from the osp routing table,
this is my conf:
debug protocols all;
log "/var/log/bird.log" all;
router id 10.10.11.10;
protocol device {
scan time 1; # Scan interfaces every 10 seconds
export all;
}
protocol direct {
interface "ppp*";
export all;
}
protocol kernel {
scan time 1; # Scan kernel routing table every 20 seconds
export all; # Default is export none
import all;
kernel table 100;
learn;
persist;
}
protocol bfd {
interface "eth1" {
min rx interval 20 ms;
min tx interval 50 ms;
idle tx interval 300 ms;
};
}
protocol ospf MyOSPF {
ecmp yes;
export filter { if (net ~ 10.10.11.0/24) then reject; accept;};
# export all;
import all;
merge external;
area 0 {
interface "eth1" {
hello 5;
bfd yes;
};
};
}
protocol static {
import all;
}
routs learned by ospf:
[root@lns-testing-01 centos]# ip r show table 100
default proto bird
nexthop via 10.10.11.11 dev eth1 weight 1
nexthop via 10.10.11.12 dev eth1 weight 1
[root@lns-testing-01 centos]#
bfd status:
[root@lns-testing-01 centos]# birdc show bfd sessions
BIRD 1.4.5 ready.
bfd1:
IP address Interface State Since Interval Timeout
10.10.11.11 eth1 Up 08:09:55 0.050 0.250
10.10.11.12 eth1 Down 08:10:41 0.300 0.000
what Im missing?
Thanks,
