<div dir="auto">I've got a multi site BIRD cluster setup in a master slave deployment. My master server is where I apply static routes with tags. Based on the tag certain communities get added during propagation. From those communities I can specify one site, several sites, or all sites receive the route. Also I have my routers and firewalls setup so that they peer with their local BIRD server. From there the route sent could blackhole, force traffic across my WAN, or force traffic out the local site Internet. <br><br><div data-smartmail="gmail_signature">Sent from my Verizon Wireless 4G LTE Samsung Galaxy S5.</div></div><div class="gmail_extra"><br><div class="gmail_quote">On Oct 3, 2017 19:16, "Robert Blayzor" <<a href="mailto:rblayzor.bulk@inoc.net">rblayzor.bulk@inoc.net</a>> wrote:<br type="attribution"><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">I am attempting to setup Bird on a VM to act as a RTBH trigger…<br>

Is there a alternative way to advertise null routes from Bird rather than using a kernel table?<br>
<br>
<br>
I have tried using static routes, but because assuming the next hop is not reachable, the routes do not export. I guess I’m looking for a way you would normally do something like a null route in Cisco and get that route into BGP. Using the kernel table at the moment is not desirable… Also other than other routing protocol peering sessions or the kernel, is there another way to get a static null route into Bird?<br>
