[AusNOG] Optimising Telstra Inbound Traffic

[Damien Gardner Jnr]

It may be that Telstra just have optus at a lower localpref, so no amount
of prepending will do it?  I have that issue with my IPv6 - I have
(expensive) Eftel, and (cheaper) Vocus/Equinix for transit - but because
Dodo are pinned to a higher localpref than Vocus/Equinix on V6, nothing
(other than dropping the session, and only bringing it up programatically
during an outage) will push the traffic via the cheaper path.
