<p>Hello, <br>
<br>
the option you want to use is `graceful restart time
<number>` as cited from the documentation at
<a class="moz-txt-link-freetext" href="https://bird.network.cz/?get_doc&v=20&f=bird-6.html#bgp-graceful-restart-time">https://bird.network.cz/?get_doc&v=20&f=bird-6.html#bgp-graceful-restart-time</a>:</p>
<dl>
<dt><code>graceful restart time <em>number</em></code></dt>
<dd>
<p>The restart time is announced in the BGP Graceful Restart
capability
and specifies how long the neighbor would wait for the BGP
session to
re-establish after a restart before deleting stale routes.
Default:
120 seconds<br>
</p>
<p></p>
<p>
</p>
</dd>
</dl>
<p><br>
And possibly these additional options:<br>
</p>
<dl>
<dt><code>min graceful restart time <em>number</em></code></dt>
<dd>
<p>The lower bound for the graceful restart time to override the
value
received in the BGP Graceful Restart capability announced by
the
neighbor. Default: no lower bound.
</p>
<p>
</p>
</dd>
<dt><code>
max graceful restart time <em>number</em></code></dt>
<dd>
<p>The upper bound for the graceful restart time to override the
value
received in the BGP Graceful Restart capability announced by
the
neighbor. Default: no upper bound.
</p>
</dd>
</dl>
<p><br>
Hope this helps!<br>
David<br>
