Isn’t it the other way around? At least I thought the "<" points to the<br>
side where the line actually is?</blockquote><div dir="auto"><br></div><div dir="auto">Yes, routinator has produced a VRP for <a href="http://200.1.154.0/24">200.1.154.0/24</a> - while rpki-client did not produce a VRP covering that prefix. The “<“ means that the line is present in the routinator output, but not the rpki-client output.</div><div dir="auto"><br></div><blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">In any case, Routinator does accept it:<br>
