<div>Hi,</div>
<div><br>
</div>
<div>I found a few messages in the archive that mention multi path and ECMP but the website says it's TODO. I was just wondering what the status is? I'm interested in having BIRD configure the Linux routing table for ECMP, if possible.</div>

</div>
<div>Thanks,</div>
