Subject: RE: Advertise loopback IP into BGP - BIRD 2.0.1
Hi Robert,
Thanks for your response. My goal is to just export lo:10 interface IP
(10.10.200.3/32) through eBGP and import all the routes on the BGP. With the
following configuration, I am able to import all the routes, but export of
lo:10 interface route is not happening. Below is my bird.conf , what is that I
am missing?
router id 198.51.100.10;
filter http_loopback {
if net = 10.10.200.3/32 then accept;
}
#protocol kernel {
# ipv4 {
# import all;
# export all; # Default is export none
# };
# scan time 20;
# persist; # Don't remove routes on BIRD shutdown
#}
protocol direct {
interface "lo:10";
ipv4 {
export filter http_loopback;
};
}
protocol device {
scan time 10; # Scan interfaces every 10 seconds
}
protocol bgp {
local 10.10.100.2 as 65110;
neighbor 10.10.100.1 as 65001;
ipv4 {
export filter http_loopback;
import all;
};
}
I have a doubt, the "show route" output is also not showing the lo:10 ip in the
table. Why is it not in the table. And "show protocol all" output under BGP
shows below, it has 6 routes received and 6 rejected for Export updates. Why is
it rejecting.
Channel ipv4
State: UP
Table: master4
Preference: 100
Input filter: ACCEPT
Output filter: http_loopback
Routes: 6 imported, 0 exported
Route change stats: received rejected filtered ignored accepted
Import updates: 6 0 0 0 6
Import withdraws: 0 0 --- 0 0
Export updates: 6 6 0 --- 0

Is your goal to ONLY export the loopback? If so, disable the kernel protocol
and either just do direct or even statics… I never use kernel as I’m not using
my servers as a router, but rather as just a route server, so I never change or
export the actual servers routing table.
You have to add an export to your direct… try:
protocol direct {
interface "lo:10”;
ipv4 {
export filter http_loopback;
};
}
protocol bgp {
...
ipv4 {
import all;
};
}
