[AusNOG] Urgent Optus BGP Communities Information

[Chris Chaundy]

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.

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...).

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.
