[AusNOG] Dealing with global route views

[Mark Tees]

Vocus additional communities have worked mostly for me in the past for inbound influence to have them send me domestic traffic. Worked partially as I think there was still some Asian traffic coming through judging from flow data at the time.

Outbound should be easy. Change preference of congested paths as required using regex and the problem AS.
