when I was running the v6ix in Wellington I was running EBGP sessions with most people who had connections; seemed to work well when I had a bunch of open-souce software mirrors which were v6-accessible and people had routes that went straight to the IX. There was also tunnel to the 6bone at Merit, for those who wanted to have a nosey at the 6bone routing table, although there were some 2000::/24 prefixes on the 6bone. I've talked to Si at Citylink about getting a PI peering block for WIX and APE, but it wasn't a huge priority. I used addresses from a freenet allocation and carved up a /64 in to a bunch of /126s and used them as point-to-point links. Not the best solution in the world, but worked for the purpose. -----Original Message----- From: perry(a)deeper.co.nz [mailto:perry(a)deeper.co.nz] Sent: Wednesday, 16 July 2003 21:43 To: Joe Abley Cc: nznog(a)list.waikato.ac.nz Subject: Re: [nznog] IPv6 -----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1

You can't plumb tunnels right now, today? Or is the problem that there's just no local place to plumb a tunnel to?

(see http://ipv6tb.he.net/ for a tunnel broker run by clueful people in the US).

ahh, but tunnels to the US mean that you have the irritating problem that pinging someone on the same ISP as you can give you up to 3,000ms of latency as it transits from here to the US and back again. You have issues when they are overloaded, or down. You have issues if the internet between here and there decides that packets should be routed via darkest peru. IPv6 was designed to work in the situation where you have to bridge large IPv4 clouds. A much better solution for people in New Zealand is to use 6to4 addressing, especially if you're on the end of ADSL or similar and don't have native transport. 6to4 addressing means that whatever device(s) have non-RFC1918 IPv4 addresses can have a /48 assigned to them. 2003:<high two octets of IPv4 address>:<low two octets of IPv4 address>::/48. To route to another 2002::/16 address over IPv4 you just take the packet, encapsulate it in IPv4, and send it to the embedded IPv4 address. Linux and FreeBSD both support this. Latency to other 6to4 addresses is about the same as IPv4, avoiding the entire US round trip. To talk from a 6to4 address to a non-6to4 IPv6 address you route via ::192.88.99.1 which is an AnyCast address. Unfortunately, last time I looked the nearest 192.88.99.1 AnyCast announcement appeared to be in Germany. Is there any chance of someone putting forward 6to4 anycast gateway in the APE and/or the WIX? Of course the problem here is that probably 50% of it's traffic will be international. In an unrelated note, the MetaNet has been used by several people in NZ who are interested in playing around with more interesting networks without breaking things that people pay to use. We use it for peering IPv6 without having to go via the US and we'd be interested in organising IPv6 tunnels with like minded people (either using wand, gre, or 6in4 tunnels) Unfortunately the MetaNet wouldn't handle multicast very well (or we'd be having a good tinker with it) Resources: * http://www.wlug.org.nz/DancingPenguin (A IPv6 enabled website in New Zealand which is useful for testing with) * http://www.wlug.org.nz/IPv6LessonsLearnt (For some random things we've discovered about IPv6 the hard way, so you don't have to) * http://www.wlug.org.nz/6to4 (Information about 6to4 under Linux) * http://www.wlug.org.nz/IPv6 (Information about IPv6 on the wiki) * http://www.nevada.net.nz/~pmurray/6to4.html (6to4 under FreeBSD) If you want to chat about it, we're usually hanging around in #wlug on Undernet. irc://undernet/%23wlug - -- <f00Dave> Look, rejects, this is #OpenGL, not #GEEKSEX. -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.2.2 (GNU/Linux) Comment: Only when you are sure they have you, can you stop being paranoid iD8DBQE/FQ0TcAgRpy8z8UQRAhadAJ4gAGn+YRABqt6A7X58K73hBQPNugCgy3ie 05qO9xRxAXyaG1K5EElVfAY= =+lkH -----END PGP SIGNATURE----- _______________________________________________ Nznog mailing list Nznog(a)list.waikato.ac.nz http://list.waikato.ac.nz/mailman/listinfo/nznog ------------------------------------------------------------------------------ "This communication, including any attachments, is confidential.
