Oh, and on your point about universities, I think you will find that most (all?) of them already peer. UoA, which is far-and-away the largest university in the country, certainly peers at APE.
AUT doesn't peer with APE because it seems a little redundant as we have a connection through Orcon, who peer at APE
You might want to ask Orcon to announce your /16 to APE peers then. A quick check from a couple of APE connected hosts shows traffic hitting TelstraClear, then AUT.
Assuming these providers also buy domestic transit from TelstraClear, AS_PATHs look like: - TelstraClear AUT - APE Orcon AUT Shortest AS_PATH wins. If they buy it from some other transit provider, who interconnects with TelstraClear: - <transit> TelstraClear AUT - APE Orcon AUT Assuming MED, etc. are the same, the oldest path will be selected. As APE routers get poked from time to time to add prefixes, the <transit> provider is likely to be the more stable. So overall, based on a few assumptions, TelstraClear wins. It's at this point that I encourage APE/WIX(1) peers to make sure you prefer routes learned over APE/WIX. LOCAL_PREF works well here to avoid AS_PATH length and age issues. -- Nathan Ward (1) And PNIX and SIX and CHIX and .. you get the idea.
