[AusNOG] OPTUS BGP Communities

[Sean K. Finn]

Hi All,

Thanks for all of your replies r.e. UDP flooding and creative BGP Techniques :)

Does anyone know if OPTUS supports Community ID's in their BGP annoucements for route selection?

I Know AAPT does, which allows us to announce our IP ranges to AAPT requesting wheter they are advertised to Australia or International peers, etc.

The rationale is that we'll select some of our links to have Australian routes only, with the other providers having no annoucment limitations, but a longer BGP path so that International traffic will prefer to come down the one link, jamming it when we get a UDP flood, and still allowing all Australian traffic to come through the other links if the designated international route is jammed with UDP.

Cheers,
Sean.
