<p>Hi Just,<br>
<br>
I've briefly looked into the configuration code and it indeed
seems like current implementation demands thread group for BFD to
be named 'express'...<br>
<br>
This is definitely an oversight and we will fix that once we have
more time on our hands.<br>
In the meantime having the warning is probably your best option)<br>
<br>
Thanks for spotting this and happy routing!<br>
David</p>

<div>Hi,</div>
<div><br>
</div>
<div><br>
</div>
<div>I've been testing migrating to bird3. I preferred to
redefine the default threading configs so that everything is
explicit, rather than implicit. But, when I defined the
¬eress" group, I got the following warning logged:</div>
<div><br>
</div>
<blockquote style="margin:0 0 0 40px;border:none;padding:0px">
<div><font face="monospace"><WARN> Symbol 'express'
overrides existing keyword</font></div>

</div>
<div>Rather than create create needless log lines, I though I
would fix that by creating my own custom thread group instead,
and use that for BFD.</div>
<div><br>
</div>
<div>I created:</div>

<div>However, the config validation then throws the following
error:</div>
<div><br>
</div>

<div><font face="monospace"><FATAL> Express thread group

<div>Is this a bug, or something I'm doing wrong ?</div>
<div><br>
</div>
<div>Thanks!</div>
