IPv6 Training?
by Alex Rubenstein 03 Jun '07

03 Jun '07

Does anyone know of any good IPv6 training resources (classroom, or self-guided)? Looking to send several 1st and 2nd tier guys, for some platform/vendor-agnostic training. Any clues? Thanks.. -- Alex Rubenstein, AR97, K2AHR, alex(a)nac.net, latency, Al Reuben Net Access Corporation, 800-NET-ME-36, http://www.nac.net

Everyone gets to decide which prefixes to accept and which to reject on their own. However, unlike IPv4, there are currently pretty much only two flavors: /32 and /48. So if you have a /32 and start announcing a bunch of /36s, or you have a /48 and start announcing /52s, it's likely that at least some people out there aren't going to accept those. (Nor /48s in blocks that are carved up as /32.) So I expect people who are in your position to start requesting blocks larger than /32 or /48 in order to be able to deaggregate, or even request multiple independent PI blocks. It will be interesting to see what this means for the number of PI requests and speed at which the global IPv6 routing table grows. It would be nice if rather than fight about how difficult it should be to occupy a slot in the routing table, with both "too difficult" and "too easy" having painful consequences, we could work something out using regional address blocks or something so it's not necessary for a router on one side of the globe to have all the more specifics that are only relevant on the opposite side of the globe. Obviously we don't want metro addressing with mandatory interconnection all over the place, but common sense suggests that there is some middle ground where it's possible to have address space that's at least portable within a certain region, but we get to prune the routing tables elsewhere.

That's not what I said. If /48 are accepted by * then people with a /32 or whatever will deagg to /48. How much and why they deagg will vary but *hand waving argument* it'll be a lot more pressure on routing table size than people doing PI You get one shot at fixed prefix size filters, miss and you'll pay forever. Which is more scarce, /32's or routing table entries. brandon

Or that its really short notice. The posting came out right before a long holiday weekend. Then the following week is very busy after such a weekend. Sorry, but my plate is to full and my ability to attend the BOF may be sketchy due to work needs.

More information and the possibilities of Multicast can be found on m6bone. One could also take a look at Radio.Unfix. ---------------------->8 And of course never forget the marvelous VideoLAN Client (VLC) and there are a lot of other tools available that can do similar things. It is one of the main reasons why we have, at least experimental, multicast supported by various SixXS PoPs. The overlay nature of Tunnel Broker setups, and relatively small scale, make that possible. Larger setups, like at ISP's, will be quite a bit more troublesome, which is also one of the reasons that Multicast is still marked experimental, as I still need to finalize the code for doing it in a scalable manner... Using ECMH (http://unfix.org/projects/ecmh/) or mrd6, which copied that same system, getting IPv6 Multicast connectivity is relatively easy. Hooking up to the m6bone can be a bit difficult, but definitely possible. Talk to the folks at the m6bone lists (http://www.m6bone.net) and they will get you sorted for sure. Something quite cool is that the Holy See (aka The Vatican :) is streaming various things onto the m6bone reaching a lot of people that way. Greets, Jeroen
