<div dir="ltr"><div><div>Hey Mike,<br><br></div> Not sure what platform you're running BIRD on, but in Ubuntu/Linux, I use loopback interfaces to do this. Here is what my interfaces file / BIRD config look like. I am using /32s, but I don't think there are any issues with /24s going into BGP. Let me know if you have any questions or I missed your questions in some way.<br><br><br></div>/etc/network/interfaces:<br><div># The loopback network interface<br>auto lo<br>iface lo inet loopback<br><br>auto lo:10<br>iface lo:10 inet static<br> address 172.22.150.126<br> netmask 255.255.255.255<br><br>auto lo:11<br>iface lo:11 inet static<br> address 172.27.255.29<br> netmask 255.255.255.255<br><br>auto lo:20<br>iface lo:20 inet static<br> address 172.22.150.119<br> netmask 255.255.255.255<br><br></div><div>bird.conf:<br><br>protocol direct {<br> interface "lo*";<br>}<br><br></div><div>/Charles van Niman<br></div></div><div class="gmail_extra"><br><div class="gmail_quote">On Wed, Mar 21, 2018 at 7:13 AM, Michael McConnell <span dir="ltr"><<a href="mailto:michael@winkstreaming.com" target="_blank">michael@winkstreaming.com</a>></span> wrote:<br><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex"><div style="word-wrap:break-word;line-break:after-white-space"><div>Hello fellow Bird users,</div><div><br></div><div>I’ve run into a strange issue trying to subnet a /24 into a series of smaller /27 and /28’s and have the routed via BGP.</div><div><br></div><div>I currently do the following; route <a href="http://10.10.10.0/24" target="_blank">10.10.10.0/24</a> reject;</div><div><br></div><div>However if I don’t bring the interface up as a /24 (i.e. ifconfig eth0:10 10.10.10.10 netmask 255.255.255.0 up) I am unable to get the route explored when I run show route - the interface needs to be online in order for “show route” to show the import as a unreachable.</div><div><br></div><div>I can kinda make this work through a series of strange static routes, but this seems incorrect.
