Hi.<br>
<br>
For this situation we may have more solutions. <br>
<br>
You can do the check only on routes that have bgp_path defined. <br>
<br>
You can add:<br>
<br>
if defined (bgp_path)...<br>
<br>
It also seems, that you are using this in an export filter. It might
be more useful to use this in a BGP import filter. In that case
every route will have bgp_path defined.<br>
<br>
I hope this helps. <br>
Happy routing, <br>
Jana<br>

<pre wrap="" class="moz-quote-pre">Hi,
In our BIRD 2.14 we’re running roa_check like this:
if (net.type = NET_IP4) then {
case roa_check(r4, net, bgp_path.last) {
However, the BIRD logs show the following error:
<ERR> filters, line 1: Missing AS_PATH attribute
would it be advisable to add a check to determine whether the route is a BGP route before proceeding?
