It feels like to check for AS 0 ROAs, we'd basically have to do two lookups for each route that's otherwise invalid, which feels inefficient. Is there a better way?<br class=""></blockquote><br class="">Probably not. Anyway, there are some plans to look into roa check efficiency, there are also going to be some aspa / as cones checks and more so we have to make it fast.<br class=""><br class=""><blockquote type="cite" class="">2) Can the output of "show route" be extended to include user defined fields, or are we locked into what's there?<br class="">3) If not, we're limited to adding communities or MEDs or local prefs or something like that, which is a hack, but at least gives us some info we can view. Is that a dangerous trade off?<br class=""></blockquote><br class="">You can declare and use your own route attributes exactly for this:<br class=""><a href="https://bird.network.cz/?get_doc&v=20&f=bird-3.html#opt-attribute" class="">https://bird.network.cz/?get_doc&v=20&f=bird-3.html#opt-attribute</a></div></div></blockquote><br class=""></div><div>This is awesome.
