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...).<o:p></o:p></p></div><p class=MsoNormal>Sorry but the news is not good.
