Hey Dean,
What are you using for the OFP controller? NOX/POX/Big Switch?
Cheers, Truman

Hi Everyone,
So the OpenFlow router has been up for a wee white now so it seemed about time to let you all poke at it. Phase 2 of the project is to: Deploy an OF switch on an exchange point which can function as a route server. This switch should be able to BGP peer with any peers which currently use the exchange and allow for the exchange of IPv4 prefixes as required.
I've used the information on the WIX Peer list webpage (http://wix.nzix.net/peers.html) to pre-configure passive[1] BGP peering sessions for all existing WIX participants.
So feel free to use your existing WIX IP addresses and AS numbers to connect to
IP: 202.7.0.119 Aut-num: 9483
Things to look for: 1) It should pass you the routes that it learns from the route servers with the Flatnet AS in the path but with the original next hops. This longer path should mean that you won't explicitly prefer the routes from me. Bit of safety there. 2) It will pass you any other routes that people pass me directly.
As I mentioned before we've got a few more plans. The next phase will start to take us a bit beyond what the current exchanges offer.
In the new year we are going to deploy a similar switch at the APE. This hardware will become part of the single SDN controlled switch that we currently have in Wellington. When you peer with the OpenFlow switch at the WIX you'll get APE prefixes as well. Peer at the APE, you'll get WIX prefixes.
Once we can get some traffic on the fabric and a presence at multiple places then we can really start to innovate.
. BGP prefix communities based on the millisecond difference between your peering port and the prefix next hop . BGP aware RPF on the exchange (solves the pointing default problem)
Got any other ideas. Throw them in the mix and we'll see what we can do.
Have a Merry Christmas everyone.
Regards, Dean
[1] Passive means that I'll never reach out and initiate a session with you. You need to initiate the session with me. Just safer incase people think that I'm TCP Port 179 hax0r-ing them. _______________________________________________ NZNOG mailing list NZNOG(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog
