Re: BGP import route
Ok. I have installed bird via epel on Centos
The router sending BGP announcement is Juniper Open Contrail Virtual Router
(on Openstack). I downloaded and installed the 2.0.2 and used this config:
-
# more /usr/local/etc/bird.conf
log syslog all;
log stderr all;
log "/var/log/bird.logg" all;
debug protocols all;
protocol kernel {
ipv4 {
import all;
export all;
};
persist;
scan time 20;
}
protocol device {
scan time 10; # Scan interfaces every 10 seconds
}
router id 192.168.200.6;
protocol bgp bgp1 {
local as 64521;
neighbor 192.168.200.1 as 64520;
ipv4 {
import all;
export all;
};
}
-
And finally I see all routes:
-
[root@vm-1 bird-2.0.2]# birdc show route
BIRD 2.0.2 ready.
Table master4:
163.162.35.131/32unicast [bgp1 20:48:36.342] * (100) [AS64520?]

Re: BGP import route
Hello!
First of all, we don't support this old version. Please upgrade, either to
1.6.4 or to 2.0.2.
Second, the other side seems to send multiprotocol NLRI to you. BIRD in 1.x
versions AFAIK does not support this extension and should not announce it. What
is the remote software?
Writing from my phone with no access to source code, trying to recall it from
my memory. I might be wrong.
