Disable Sender Side Loop Protections
Hello - I ‘m currently building a lab mockup of our network and using Bird the fake routers for the “internet”. A part of this mockup is having two to routers peer into the internet with the same AS and be able to receive the routes from the other. Juniper has this ability with the configuration option “advertise-peer-as”. I have read through the documentation, but can’t seem to find a configuration option to achieve the same thing. Is this possible with Bird? Charles Rumford Principal Infrastructure Architect charlesr@summithq.com<mailto:charlesr@summithq.com> O (312) 268-9342 [Summit]<https://www.summithq.com>
Hi Charles, I think this is what you are looking for: https://bird.nic.cz/doc/bird-2.18.2.html#bgp-allow-local-as Regards, Alexander Zubkov On Mon, Jul 20, 2026 at 6:00 PM Charles Rumford <charlesr@summithq.com> wrote:

And if you mean loop verification by sender, AFAIK there is no such check in BIRD. So there is no knob for it. On Mon, Jul 20, 2026 at 6:03 PM Alexander Zubkov <green@qrator.net> wrote:
