Hi,
how can I check which prefixes are not valid and so rejected? It seems the
rpki is working, but I'd like to be sure. I have this:
if (roa_check(r4, net, bgp_path.last) = ROA_INVALID) then
{
print "Ignore RPKI invalid ", net, " for ASN ", bgp_path.last;
but I don't understand where the prints
Thanks!
But can I also use birdc to check rejected prefixes?
Anyway why do you suggest to use bgp_path.last_noaggregated?

Good evening,
I have this kind of bird.conf:

in master table routes learn by BGP. But I don't understand why in the Pipe
protocol in combination with BGP is useful to have the 'export' clause

Good morning,
how can I see the as path of a route?
I think the command is 'show route' and I get:
192.168.5.0/24 unicast [bgp1 ...]*(100) [AS3i] via..
What is 100?
AS3 should be the as path, right? Why is there an 'i'?
Thanks,
Fabiano

Hi all,

Hi everyone,
when I try to set up a password for a BGP peering the connection state is
Connect and not Established, so BGP is not importing prefixes.
The neighbor which is doing a peering is a Cisco router and I set up the
password with neighbor ip-address password string command.
Thanks,

ipv4 {
import all;
table t4;

Without password it is working.

Hi all,
which is the proper way to start Bird?
I edited the bird.conf and now I am getting this error when I lunch birdc:
Unable to connect to server control socket (/usr/local/var/run/bird.ctl):
Connection refused
I also did bird -p
Thanks,

According to the documentation the socket is in *prefix*/var/run/bird.ctl
Anyway if I run bird I get this error:Cannot create control socket Address

Hi all,
why if I disable the direct protocol the BGP routes are not
imported/exported? If I run show route, it is empty, while if I enable the
direct protocol show route has directly connected routes and BGP routes.
My configuration is very easy, two routers make a eBGP peering and they
import and

Good evening,
Before I was using Ubuntu and to enable the RPKI protocol I did:
./configure --enable-libssh.
Now I am a new Centos7 user and I don't know really well how to enable
RPKI.
I downloaded bird2-2.0.6-1.el7.x86_64.rpm

How does roa_check(roa_table,net,bgp_path.last) work?
Having such a ROA as example:
origin AS: 64513
prefix: 78.150.40.0/20
max mask: 24
and a BGP announcement:
origin AS: 64514
prefix: 78.150.45.0/22
so it's as invalid, but how does this check work?

I am using a text editor on Windows to edit the bird.conf. When I get my

But everything is right.
How can I solve?

Hi all,
is there a way to check quickly filtered RPKI routes?
I can check the syslog, but if I delete the log I think the only way to
check filtered routes (having import keep filtered enabled) is:
show route table table_name all filtered
but having a lot of tables it is not easy to handle this
?
Thanks in advance,
Fabiano D'Agostino
