<div dir="ltr"><div><div>I have the Evolve FAQ and my interpretation of the community above is that routes advertised *to* customers are tagged with the community to indicate the source, but tagging routes advertised *from* customers to Optus with the community will have no policy impact whatsoever.<br>
<br></div>In general, all the 7474:1xxx communities are used for atgging this way (7474:14xx for international route origins and 7474:12xx for domestic route origins). The only customer-applied communities that can influence policy appear to be 7474:21xx which block advertisement to their various domestic peers along with the standard RFC1998 local-preference settings. There do not appear to be any communities to block international advertisement (this would have helped with some recent configuration I was doing if there was!). Whilst on the topic, I wish that they supported RTBH like most of the Tier 1 providers do (and Telstra also don't...).<br>
<br></div>Sorry but the news is not good. All you can really do is AS path stack, but then that may/will distort other traffic flows as well.<br></div><div class="gmail_extra"><br><br><div class="gmail_quote">On Fri, Apr 11, 2014 at 3:46 PM, Beeson, Ayden <span dir="ltr"><<a href="mailto:ABeeson@csu.edu.au" target="_blank">ABeeson@csu.edu.au</a>></span> wrote:<br>
