Hello,
if some one is interested in doing the backporting, something has been done for quagga on this link:

How could I help in solving this problem? Very interested.

@mdash-vmware @donaldsharp @pguibert6WIND @kssoman @liuxyon @eqvinox @qlyoung
Maybe someone already has a solution?

[ton31337]

I have almost working branch, just needs some fixes.

[BitSums]

@ton31337 help you with tests?
If so, write a checklist.

[ton31337]

I’ll update you when back to this issue, ok?

[BitSums]

Well thank you.
I will wait.

[BitSums]

@ton31337
I beg your pardon, but when should I expect?

Hello!
Faced a similar problem in the opnsense distribution. I see it has been solved for a long time and no progress so far.
I really need this functionality and I would like to ask when will there be at least some progress?

I used gobgp to achieve the goal and bird and everywhere I get this error.

@workeberies @BitSums could you guys please tell me how do you test this capability? I would love to test it locally before pushing and write a test for this capability as well.

Hey.
I recently encountered the same problem on FRR 7.2.
I tried to address the white address with bird 1.6.3 on ubuntu 18.04, config:

nano /etc/bird/bird.conf

log syslog all;
router id 192.168.1.157;

protocol kernel {
        scan time 60;
        import none;
#       export all;   # Actually insert routes into the kernel routing table
}

protocol device {
        scan time 60;
}

protocol direct {
        interface "venet*", "tun*"; # Restrict network interfaces it works with
}

protocol static static_bgp {
        import all;
#        include "pfxlist.txt";
        #include "iplist.txt";
}

protocol bgp OurRouter {
        description "Our Router";
        neighbor 192.168.1.1 as 65535;
        import none;
        export where proto = "static_bgp";
        local as 65009;
        passive off;
        multihop;
}

What do you mean here _white_?

It's about the IP address - white.
That is, my task is to run services on a white address in the place where I use bird.

I have this scenario with me:
freebsd 11.2 - frr
ubuntu 18.04 - bird

On ubuntu I have to start the service (nginx, for example) on the white ip (195.112.90.39) address, and not on the gray one (192.168.1.157 - gray).

[ton31337]

that’s fine, how many prefixes do you have in those lists?

[Rockvere]

[Rockvere]

On 6.0.2 a similar problem.

[ton31337]

version doesn’t matter at all because it’s not implemented

[ton31337]

@Rockvere can you join FRR slack channel?
