<div dir="ltr">Hello.<div>BFD is Not working normally.</div><div>My configuration is shown below.</div><div><br></div><div>OS: Ubuntu 18.04</div><div>Kernel: 4.15.0-54-generic</div><div>BIRD ver: 1.6.8</div><div>==================================</div><div>protocol bfd {<br> multihop {<br> min rx interval 300 ms;<br> min tx interval 300 ms;<br> multiplier 3;<br> };<br>}<br></div><div><br></div><div>protocol bgp as1 {<br> import all;<br> export all;<br><br> local ~ as ~;<br> neighbor ~ as ~; <br> enable route refresh off;<br> hold time 90;<br> bfd on;<br>}<br><br>protocol bgp as2 {<br> import all;<br> export all;

BGP neighbor is established, But BFD sessions are stuck in 'INIT' status. And BIRD does not send BFD packets.<br></div><div>BFD sessions have recovered after restart protocol bfd1(# birdc restart bfd1).</div><div><br></div><div>Is it a normal situation?</div><div>I think BFD has to start the mechanism after BGP neighbor is UP.</div><div>Is there any missing part of my configurations?<br></div><div>Please check it.</div><div><br></div><div>Regards</div></div>
