[c-nsp] Peering + Transit Circuits

[Scott Granados]

So in our case we terminate peering and transit on different routers.  Peering routers have well flow enabled (the one that starts with a J that’s inline).  With NFSEN / NFDUMP we’re able to collect that flow data and look for anomalous flows or other issues. We pretty much detect and then deal with peering issues rather than prevent them with whitelists and so forth but then again we’ve been lucky and not experienced to many issues other than the occasional leakage of prefixes and such which maxprefix handles nicely.

Thanks
Scott
