</span>Hi,<br>
<br>
You are looking for filters. These define rules that get checked<br>
against every route imported/exported and can either accept/reject a<br>
route or can even modify attributes. Filters can be applied on export<br>
to control what you advertise, and on import to control what you<br>
accept.<br>
<br>
I would normally leave you to figure out the details by yourself,<br>
however the documentation isn't exactly the best at telling you how to<br>
do these simple tasks so it would probably save a bit of time if I<br>
gave you an example.<br>
<br>
filter senddefault {<br>
if net = <a href="http://0.0.0.0/0" rel="noreferrer" target="_blank">0.0.0.0/0</a> then accept;<br>
reject;<br>
};<br>
<br>
and the v6 version would be<br>
<br>
filter senddefault {<br>
if net = ::0/0 then accept;<br>
reject;<br>
};<br>
