[AusNOG] Influencing Routes

Announcing it within AU should do the trick, 98% of the time with the other
2% providers transiting back to LAX due to their traffic policies. (Made up
numbers but you get the hint:))
You *could* also ask the AU transit provider nicely to advertise the /24 to
a domestic/AU only audience and that would mean all AU traffic stays
locally!
Gday Guys

Thanks for the responses thus far,

So I should keep the BGP to my LAX provider, and also establish another one
back to AU and announce it through my Sydney provider?  So theortically it
will be a shorter path into Sydney > GRE > LAX Router   then over the SCC
and a heap of extra hops

Is that correct?

easist solution is to just run BGP on the GRE tunnel assuming you're
advertising PI space in both locations.  advertise the /24 over the tunnel.

if the /24 is owned by the LA overseas provider you'd have to ask them for
permission to readvertise, and for them to advertise it as a /24.
