<p>Well there is <em>some</em> progress, yet probably not complete, see

<p>I would like to use dynamic bgp (using a range for neighbour) with
auto-configured LL IPv6 adresses. This doesn’t work, of course, if I
need to statically configure the source address, which I am forced to
with the strict bind option. […]</p>

<p>With BIRD 2.18, you should be able (and I may be wrong because I
implemented it half a year ago) to have <code>strict bind</code> with
dynamic link-local and <code>interface</code> set. I have no idea
whether your needs would be met completely with this version but if you
could check please …</p>
<blockquote>
<p>I am wondering, is this restriction really needed? There is only one
IP address (the LL one) on the interface in question (and the interface
is specified in config). I think this should mean that bird could just
pick that IP address and use it for both source as well as to bind to.
If that is true, could a “source address auto” option or so be added to
allow such a configuration?</p>
</blockquote>
<p>If it’s ok that it would choose the source address kinda randomly
from that interface, it’s probably a feature worth adding. And because
we did some BGP listening reworks, it should actually be trivial now,
while for 2.17 and older it wasn’t.</p>
<blockquote>
<p>In addition, it would be great if a strict bind option could be added
for the babel protocol.</p>
</blockquote>
<p>Noted finally, sorry for missing that.</p>
<p>Thanks for the heads-up, have a good new year!<br />
