[AusNOG] OPTUS BGP Communities

[Bruce Morgan]

Hi Sean,

Don't forget the upstreams. You could use RFC1998 tags but you may  
wish to signal Singtel rather than Optus, eg 7473:70. Not sure what  
Optus may do to your tags on ingress, but we've used it successfully  
in the past

YMMV

regards

Bruce
