[07:16:43] comment: with the most recent proposal RFC 3484 bis, 6to4 would be deprioritized compared to IPv4, so if most rogue RAs are 6to4, no other solution may be needed? [07:16:48] Bjoern A. Zeeb joins the room [07:17:17] Simon Leinen joins the room [07:17:38] fdupont joins the room [07:17:48] Tomas Podermanski joins the room [07:17:51] Bernie joins the room [07:18:10] danwing joins the room [07:18:11] simon - not quite that simple [07:18:43] happy eyeballs implementation report [07:19:00] mg joins the room [07:19:03] removing rogue RA is something any service provider should do, it's basic stuff. Don't let customers talk L2 to each other. [07:19:32] Ole Troan joins the room [07:19:36] implmentation of happyballs in draft in erlang [07:19:40] Which presentation are we at the moment?

It is very wudely used [07:24:40] we'd like to put this impletementation into an http proxy so that we can use it with convention values [07:25:19] question from janos [07:25:31] dudisaki joins the room [07:25:48] it would break the round robin load balancing. [07:25:49] ywang830 joins the room [07:26:11] Happy Eyeballs works fine with DNS load balancing. [07:26:13] andri yourshecko - we do parallel attempts with different address families [07:27:39] jan ker - didn't head that very clearly - I don't disagree - why is dns spamming considered out of scope. think it's out of scope. [07:27:46] no api's? [07:27:52] fred - we do do apis [07:27:59] jeff huston preso [07:28:20] http://tools.ietf.org/agenda/80/slides/v6ops-1.pdf [07:28:28] Agree with Fred: We should work on API to help proper behaviour - like happy-eyeball [07:28:32] someone is breathing into a mic... it's not too annoying, but... [07:28:35] look at the problem from the side of the server [07:28:41] sorry [07:28:52] Dave Thaler joins the room [07:29:21] g.e.montenegro joins the room [07:29:45] when you look at the world from the vantage point of how much does a server see you see a huge amount of capability, new experiment every time it runs [07:30:06] ywang830 leaves the room [07:30:12] v6only test is using ipv6 lteral e.g. no dns [07:30:16] jpc joins the room [07:30:44] full blown tcpdump along with typical server logs [07:31:07] ywang830 joins the room [07:31:16] dual stack failures are interesting [07:32:09] the internet is remarking hetrogenious not homogenious, apnic site users about 5% will prefer v6 [07:32:31] on a more popular site it's more like .02 % [07:32:43] ywang830 leaves the room [07:32:49] v6only is 4% [07:33:20] why are there 20x more folks that could use v6 but don't use it [07:33:35] 6to4 is enabled by default if you have a GUA on windows vista/7 [07:33:47] gl joins the room [07:33:50] but they don't prefer it [07:33:57] ywang830 joins the room [07:34:05] if you perfer v6 in autotunneling things get pretty rough [07:34:54] folk coming in on v6 unicast seem to do so at about the same rate as ipv4 [07:35:04] narten joins the room [07:35:16] the penatly for 6to4 is around 1.2 seconds [07:35:40] teredo setup is at least 1rtt [07:36:26] behcet.sarikaya leaves the room [07:36:28] Bruno STEVANT joins the room [07:36:35] tried to mitigate 6to4 but putting v6 relay in the server [07:36:38] ywang830 leaves the room [07:36:45] behcet.sarikaya joins the room [07:37:01] 6to4 has almost no setup time penalty [07:38:18] measure tcp-3way tunnel setup penalty at 150ms median peak [07:38:38] rjs joins the room [07:39:05] if you think that's bad lets look at teredo [07:39:34] if the only interface you have is teredo it will not retrieve quad a [07:39:51] only exercised for literal [07:40:12] 30% of clients can pull down the object using terredo [07:40:28] imense capacity for v6 [07:40:56] distribution of setup time, seems to take around 2/3 of a second to setup [07:40:58] ywang830 joins the room [07:41:12] peak at 2 seconds and 3 seonsd [07:41:27] tunnel rtt cost is about 300ms [07:41:41] some clients get away with almost no added cost [07:41:54] if you're on unicast v6 be happy and smile [07:42:06] if you're on tunneled v6 turn it off it's crap [07:42:31] dual stack failure (.6%) [07:42:41] we're not sure why [07:43:16] number is high but unreliable. [07:43:24] which is the current slide? [07:43:26] where are we ? [07:43:29] :) [07:43:30] how many folk can send me a syn but not an ack [07:43:53] connection failure is the title of the slide [07:43:57] ("how many naked SYNners?") [07:43:59] I'd say 36 [07:44:20] 35-37 is connection failue, so that is good enough [07:44:26] v6 connections work better at home. [07:45:06] failure rates for unicast v6 are 2-4% [07:45:19] NAKed SYN [07:45:52] teredo connection - how many folks send me the icmp packet and nothing else [07:45:56] I like the humor O:) [07:46:07] tetsuya.mrk@jabber.jp leaves the room [07:46:14] terredo failures = 25% [07:46:18] er 35% [07:46:25] what slide are we at? I can't find that slide... [07:46:32] one third of all teredo connections fail [07:46:34] 40 [07:46:46] 40 is a conclusion slide in my slide set? [07:47:00] 12-24% of 6to4 failure due to protocol 42 filtering [07:47:21] 38% of teredo fail [07:47:22] get v6ops-22.ppt [07:47:25] Comment: (Tore Anderson) Regarding 6to4 relay congestion being unlikely due to the low levels of 6to4 traffic: I understand that most of the relayed 6to4 traffic is actually BitTorrent traffic that is rendezvousing with Teredo. This is of course invisible from the web server vantage point, but it might anyway cause congestion on the same 6to4 (and Teredo) relays that also handle the web server traffic that are actually observed in the experiments [07:47:36] due to icmp filtering [07:48:14] you also don't like outgoing udp ice/stun/turn probably don't work either [07:48:33] (that was for the mic later) [07:49:07] Tore: We have more than 100 Mb/s on our 6to4 relay right now; looks like most of this is indeed BitTorrent. [07:49:13] if you want to run v6 tunneling today don't [07:49:35] help us, see url labs.apnic.net [07:49:55] simon l - thanks for imperical work [07:50:10] p2p works much better than non-native to native (which is actually related to why Windows doesn't do AAAA queries if it just has Teredo, as Fred said... by design) [07:50:28] when I looked at graph with rtt cost wondering if you cut at zero [07:50:40] jeff small numbers on the other side [07:50:46] (p2p = 6to4-to-6to4 or Teredo-to-teredo) [07:51:07] simon l - should it be depricated [07:51:13] jeff - killed [07:51:30] simon l would it be better to turn it off [07:51:47] igor - killing relay isn't effective kill os. [07:52:10] igor g - do they have unique hosts names [07:52:26] jeff - there is not ability to cache the dns [07:52:45] (geoff) [07:52:47] igor - counting dns failure rate is atrocious [07:53:29] geoff - this is tcp failure counting so the dns failures don't show up [07:53:57] igor - thanks this awesome [07:54:39] rajev - if we look at the data from the weekend do we draw different concusions about tunnel performance. [07:55:10] geoff we don't consider 12% failure as drammatically better than 20% it's just bad. [07:56:26] lorenzo c - the results match what we see, we've been looking at the network, we have certain large isps with peaks around 3-4% [07:56:27] g.e.montenegro leaves the room [07:57:00] geoff would that we had more data, we seem to have tiny aperatures. badness clumps [07:57:08] lorenzo - we have more data [07:57:09] carolin joins the room [07:57:24] the time for automatic tunneling has really passed [07:57:38] some operating systems and home routers should turn it on by default [07:58:11] we'll discuss this later but I think that a statement from this body supported by this data would be helpful. [07:58:16] comment to Lorentzo: connection from automatic tunneling to native IPv6 is not preferred by default per RFC 3484 [07:58:37] geoff we can't hop over brokeness in the isps netowrk. [07:58:52] lorenzo - don't try and make pigs fly [07:59:36] it is insane to insist on deploying a transition technology half-ass, then blame it for failures.. [07:59:54] mark t - qualify statement, in a controlled environment we can hop over v4 netowrks [08:00:15] bless joins the room [08:00:38] if the content providers deployed 6to4 on their end the path would be exactly the same as IPv4 door-to-door [08:01:21] message for providers: control the path - probably help your 6to4 and teredo users! [08:01:21] ywang830 leaves the room [08:01:24] adrew [08:01:27] http://tools.ietf.org/agenda/80/slides/v6ops-21.pptx [08:01:29] ywang830 joins the room [08:01:43] slide 4 [08:01:52] changes slide 5 [08:02:10] +srv records sections [08:02:11] jham joins the room [08:02:11] hsalgado joins the room [08:02:16] +mif reference [08:02:25] + debug strawman [08:03:12] becarpenter joins the room [08:03:18] todo slide [08:03:25] need more implmentations [08:03:32] hysterisis problem [08:03:52] need pluggable name based connect api [08:04:05] write seperate draft for that? where to take it [08:04:44] comments [08:05:00] fred - int agrea? [08:05:05] jari a - yes [08:05:32] hsalgado leaves the room [08:06:18] dave thaler - microsofts pm's went to content providers level of concern about multiple simulatnious connections and pontetially large number of resets [08:06:34] major agreement that problem needs to be solved. [08:06:52] can we do a better job about which one to try first [08:07:13] maybe p could actually be fairly large if you had a good guess [08:07:32] mark andrews - happy eyeballs is a really generic problem with multihomed machines [08:07:34] Agree with Dave Thaler: Some providers blacklisting clients with high syn and rst rates [08:07:47] um addressing that problem might actually a better problem [08:08:14] fred - some sort of memory about specifc addresses or prefixes [08:08:49] I actually think you should do this for source × destination [08:09:49] igor - I'm going to disagree with that sorry, as on operator I'll take the pain from happy eyeballs over the pain from not haivng happy eyeballs [08:10:26] per prefix or per destination memory plus address family memory might mollify providers [08:10:31] g.e.montenegro joins the room [08:11:01] adrew - feedback needs to be incorporated into the list [08:11:12] Agree with Simon Leinen. That is the correct solution as I have written earlier on v6ops mailing lists: RFC 3484(bis) can be used as a hint what makes sense and what is not. [08:11:14] http://tools.ietf.org/html/draft-ietf-v6ops-multihoming-without-nat66 [08:11:55] 1wglc ended - name cahnges [08:12:45] @simon: be careful, you need to it converge fast. starting with 0 knowledge for every s*d would be bad. That was my point about sharing knowledge so you guess right the first time almost always [08:12:46] I disagree with Thaler, because a Happy Eyeballs user will _not_ be sending a lot of SYNs and RSTs. "P" prevents them from doing that. It's only the first connection that would be in parallel. Subsequent connections will continue to trend towards IPv6 (if it's working) or towards IPv4 (if it's working). And content providers have one, and only one primary job in life: deliver content. Happy Eyeballs is aligned with that goal. Which Igor re-inforced at the mic. [08:12:58] definition of multihoming - intended to address small sites and preserve end to end transparency [08:13:05] rvdp joins the room [08:13:06] @dan: I'm just channeling what others said [08:13:11] understood. [08:13:23] expanded security considerations section [08:13:26] it's the first connection from every client to every destination [08:13:38] I perhaps should have said "the content providers quoted by Thaler are confused, in that they did not understand how "P" in the draft works." [08:13:39] next steps? [08:13:48] fred - net feedback [08:14:00] thats why I explicitly stated I didn't know for sure whether the feedback still applied to the current version [08:14:36] http://tools.ietf.org/agenda/80/slides/v6ops-4.ppt [08:14:50] fred t - tunnel looping [08:14:59] problem - [08:16:13] mitigations - [08:16:57] don't use onlink prefixes at all [08:18:16] @Thaler: one extra connection, of the ~40 they are receiving, is going to cause them harm? I am /very/ doubtful. [08:18:27] @Thaler: Happy Eyeballs has always had "P". [08:20:27] on the previous slide, I don't understand why an ISP would ever want ISATAP [08:20:50] @dan: it's possible they were confused, I can't say as I wasn't the one who talked to them :0 [08:20:52] :) [08:20:53] requirement [08:20:56] s [08:21:01] swb leaves the room: Replaced by new connection.

I believe rogue RAs are less prevalent on dual-stacked networks than on ipv4-only networks (although certainly not absent) [15:58:24] 6to4 is out there [15:58:35] behcet.sarikaya joins the room [15:58:50] fred question for the house [15:59:14] seen the basic recomendations do you feel it's a wg draft [15:59:20] Matej Gregr joins the room [15:59:34] oula - wait for three drafts [15:59:48] http://tools.ietf.org/agenda/80/slides/v6ops-13.pptx [15:59:56] SJX7ED15CEF joins the room [16:01:03] victor k - level-set we still belive native v6 is the best solution [16:01:28] that mic is useless [16:02:45] 6to4 is challanging especially when covered by carrier grade nat [16:02:56] cgnat is already out there [16:03:41] legitimate uses of non-rfc1918 addresses behind cgn [16:04:40] sm joins the room [16:04:45] noted it's low cost, runs on existing relays [16:04:59] tested since bejing [16:05:07] can't undo some bhallenging [16:05:24] p2p with another 6to4 doesn't work [16:05:59] referrals to the address are "challenging" [16:06:18] behind a cgn it's either broken or it's not. [16:06:31] works for the use case we defined [16:06:51] would this be considered as a use case for 6to4 behind cgn [16:07:05] sdstrowes joins the room [16:07:06] still a symertic nat [16:07:27] oul tero [16:07:39] oula [16:07:41] ole trøan :) [16:07:48] ah [16:07:52] better [16:07:56] will correct [16:08:18] can't hear up here not speakers on stage [16:08:26] http://tools.ietf.org/agenda/80/slides/v6ops-5.pptx [16:08:57] summary - make 3056 and 3068 historic [16:09:07] what is historic [16:10:00] if it's superceeded or made obsolete by another specificaion or no longer used [16:10:28] pretty sure protocol 41 is not getting through [16:10:55] says this is technology that the ietf will not evolve any further [16:11:11] wes george - we have to struggle with the definition of hitoric [16:11:22] danwing joins the room [16:11:28] better footing that the ipv4 proposal [16:12:05] good to differentiate between turning it off in the host vs don't turn it off in relays [16:12:43] fred - precident widely used protocol taken to historic [16:12:46] ripv1 [16:13:22] what protocols are supported in cpe, every one of them supported ripv1 [16:13:32] ripv1 had not context for cidr [16:14:13] was not to say don't use it. [16:14:16] that mic is still useless [16:15:06] brian carpenter - we should do both e.g. you can consider victors draft and oles at the same time [16:15:36] ole - i need this document for our linksys people [16:15:51] mark handley - stole my anecdote [16:16:10] another certification body says do this ietf thing [16:16:15] it was a lot more work [16:16:36] we managed to knock that one down [16:17:06] dave thaler - same thing as brian, wrong question, [16:17:39] second point I liked it two issues tryingto depricate two different rfcs less justification for 6to4 [16:17:46] bc [16:18:02] 's presentation covered potential justification [16:18:41] regarding 3484 if it changes that the title needs to reflect it [16:18:54] primary problem is for relays [16:19:15] what fairly easy to do without code changes is to tell it not to use the relay [16:20:00] diagrem and then question to the working group [16:20:46] tim chown what do we use behind a host instead of 6to4 for connection sharing [16:21:05] igor, guidance for making it better and btw don't use it [16:21:35] for me, 6to4 should go away asap, both the relay and the direct version. Mikael Abrahamsson [16:21:52] because it's protocol 41 and it's everywhere p2p and relay are both pbroken [16:22:04] ole -have a list of cdrafts for other protocols [16:22:21] jordi - making the protocol historic vs making anycase historic [16:22:58] ole - this draft asys depricate the whole thing [16:24:03] lorenzo - I hate to think of anything else going through it, if it's hard for us [16:24:25] it will break everything else [16:24:38] if it means depricating relays that fine [16:25:16] igor - depricate 3068 [16:25:55] geoff h - there are many ways that 6to4 can fail, in the methodology I used I did not use failures due to relays [16:26:21] the only failure I was seeing was really narrowed down to protocol 41 [16:26:37] I can't measure thet failures that don't get to me [16:27:15] brian - it's impossible to tell how many people get into the happy eyeballs [16:27:41] I don't belive 3056 is broken [16:27:57] nobody deployed it [16:28:33] it's true that what microsoft did is that when folks use the dns to rendezvous you don't see much teredo [16:28:59] when I simulate that I get a huge number of folk who try to connect to me in terredo [16:29:11] you will get 3056 between two end sites when the end users both have CPEs that implement it by default and send out RAs by default. and what happens then? the end hosts have 1) an IPv6 address - the 6to4 one, and 2) a default router - the CPE. this is a recipe for end-user brokenness. [16:29:38] whatever is going on in terredo the failure rate is right up there. [16:29:56] james woodyatt joins the room [16:30:02] 95% of v6 I see is teredo [16:30:15] if possible, relay to mic [16:30:18] james woodyatt leaves the room [16:30:26] james woodyatt joins the room [16:30:28] tore ok [16:31:19] bnsmith joins the room [16:31:30] (tore anderson, redpill linpro) btw [16:31:56] wess geroge [16:32:03] yup [16:32:07] thanks [16:32:16] Dave Thaler joins the room [16:33:02] mark h if we do something less than depricate everything if we leave the door open then disable by default needs to be in there [16:33:10] igor [16:33:52] in that sprit optional should be considered harmful and is ill-advised [16:33:54] That would be going to far. [16:34:14] erik kline +1 for depricating 3068 [16:34:26] should we ask all current vendors to turn it off if it was default-on before? Should microsoft send out patches to turn it off? [16:34:44] consider whether on no we want to save 2002 in global scope [16:34:46] without a relay, 2002 is same as a common ULA [16:35:32] eric - what is the status of ipv6 nat 6pt is what I would b thinking of [16:35:49] fred - calling the the question [16:35:54] this is my sumamry [16:36:28] part of the question has to be is this the recomendation we want to make [16:36:53] do you belive that this in general is the way we want to go [16:36:54] danwing leaves the room [16:36:54] hum [16:36:57] I believe not.

[16:39:16] ? - lack of readiness [16:39:36] I just don't care. [16:39:40] lorenzo - ipv6 day is not about deployemnt, we can't deploy it in two months [16:39:54] it's about finding problems [16:39:58] No — religious bias [16:40:12] igor - if it comeso ut first it's useful ammunition [16:40:38] mark handly - the bullets are nice and be captured in one of the documents [16:40:45] this decision should not be driven by intentional deployment in a way that breaks it [16:40:46] townsley [16:40:50] it was a nice roadmap [16:40:59] yeah sorry [16:41:29] dave thaler suggest a cross rference but informative [16:41:53] ole - terrredo to historical help? [16:42:33] http://tools.ietf.org/agenda/80/slides/v6ops-15.ppt [16:42:47] That comment was about IT departments that have not deployed IPv6 but are providing public IPv4 to the hosts [16:43:04] experience of recomendations from software [16:43:57] softwire [16:44:04] ICP = ?

[16:44:19] wondered about the same thing [16:45:45] communication scenarios - [16:46:44] two major first, ipv4 - ipv4 for most current applications and ipv6 - ipv4 for p2p [16:47:38] cgn brings a lot of cost [16:50:08] enumeration of changes required by solutions [16:52:25] user management and logging requirements by solution [16:53:21] address consumption by solution [16:54:19] punchline - ipv4 address sharing is complex [16:56:09] danwing joins the room [16:56:59] need a more scalable address sharing mechanism [16:57:11] who is speaking [16:57:45] can't see badge, it's backwards [16:59:30] didnt' catch name ether [16:59:34] from TI, I know that [16:59:40] think the intro was , telecom italia [16:59:50] yes, telecom italia I heard as well [16:59:55] thanks [17:01:06] Roberta Maglione [17:01:19] thanks [17:01:37] jpc leaves the room [17:01:38] randy - shes correct dslite can easily go that path [17:02:29] danwing leaves the room [17:02:34] raj - where do you see the stateless getting differentiated [17:02:47] danwing joins the room [17:04:52] shin m - pros and cons stateless divi it still dificult to identify behavior [17:05:15] natt444 can do static [17:05:46] mark t - I'm a big fan of stateless mechanisms when they're possible, they're not always possible [17:06:25] ? - wondering what you want to do with this work [17:07:10] fred - nice to capture this information in an internet draft [17:07:28] voichek [17:07:40] tunneling work needs to work to softwire [17:07:50] value in the operational discussion. [17:08:07] Dave Thaler leaves the room [17:08:45] tamo fortsinghua university [17:08:51] from [17:09:40] ɹəlɐɥʇ əʌɐp joins the room [17:10:25] jari a - in intarea we discussed stateless mechanisms and agreed to work on stateless. [17:10:31] fred software? [17:10:39] softwire? [17:10:39] ɹəlɐɥʇ əʌɐp leaves the room [17:10:43] jari - yes [17:11:46] telecom italioa - motivation document in softwire is called stateless solutions [17:11:49] ɹəlɐɥʇ əʌɐp joins the room [17:12:01] wej joins the room [17:12:08] mark t - not supposed to specify the actual bits [17:12:37] architecturaly both solutions are a tunnel divi or 4rd [17:12:48] jari a what mark said [17:14:05] tina - reduce burden of statefull transition [17:14:18] fred - softwire is the place to have the future discussion [17:14:36] http://tools.ietf.org/agenda/80/slides/v6ops-2.pdf [17:15:02] tina tsuo - [17:18:13] end [17:18:22] comments [17:18:26] thanks [17:18:38] http://tools.ietf.org/agenda/80/slides/v6ops-20.ppt [17:19:15] dong zang [17:20:46] problem is identification of end-user [17:20:59] through nat translation [17:21:14] hostid is another potential example [17:22:30] What is a DPI box? [17:22:45] deep packet inspection [17:22:49] L7 box [17:22:49] Ah. [17:23:10] what does IVI stand for btw? in D-IVI ? [17:23:12] comments [17:23:30] I failed to find a draft that actually explained the acronym [17:23:34] shin - this is a cgn requirement and we are working on that [17:23:42] many use it, none explain the acronym [17:24:11] IETF Policy on Wiretapping [RFC 2804] is relevant to this draft. [17:24:28] it is... [17:24:49] fred - it can't be done here it's a protocol [17:25:07] It contains no reference to RFC 2804. [17:25:29] the author needs to revise at a minimum [17:25:33] behcet.sarikaya leaves the room [17:26:07] I concur. If there is IETF work here to do that doesn't conflict with IETF policy on wiretapping, then it's far from clear to me what that would be. [17:26:31] these usecases are not helpful. [17:26:50] james, that should probably find its way to the mic [17:26:51] fred - at a minimum it do people find this useful, the question is where to do it. [17:27:04] Would somebody please carry my comment to the microphone? [17:27:06] I can channel james [17:27:37] I'm *not* saying I don't think there's work for IETF to do. I'm saying I don't see what it is. [17:27:45] chris morrow we have lots of methodologies to address this [17:27:56] tsavo_work@jabber.org/Meebo joins the room [17:28:00] the TI speaker from before is Roberta Malone [17:28:16] tina t - in the cgn enviroment this one connection may belong to different users [17:29:39] as to the question of hether this work would be useful I think it will be useful and needed. [17:29:58] in the case of a cgn it identifies thousands of subscribers [17:30:05] there are use cases here [17:30:22] lee howard [17:30:40] telecom italia - this is useful we need traceabck [17:30:51] It's categorized as Informational. That's proper. I would prefer to see an explicit reference to RFC 2804 anyway. [17:30:53] other use cases in internet area [17:31:04] shin - says this is ueful but not here. [17:31:25] we have discussed this in software [17:31:46] randy the you who wants to know who I am is i am [17:32:13] becarpenter leaves the room: offline [17:34:37] is leo [17:35:36] speak into the mike [17:35:40] mic [17:36:03] Thanks, Joel. [17:36:04] The I-D is inadequate to meet law enforcement's needs, anyway. [17:36:19] dudisaki joins the room [17:36:25] igor - while I'm not adocating this randy it does provide a more fine grained method [17:37:08] adri yochecnko - a hit to a serivce provider [17:38:08] Packetgrrl leaves the room [17:38:13] fred - talk to jari about what next steps should be [17:38:24] http://tools.ietf.org/agenda/80/slides/v6ops-3.pdf [17:38:32] lee howard [17:39:13] sdstrowes leaves the room [17:39:34] I must leave the room for this draft. [17:39:39] james woodyatt leaves the room [17:39:48] state menchaism for verious technologies in which order to be used [17:41:11] do we need to support multhominh [17:41:19] requirements from smartgrid [17:41:53] alain durand - pcp ? [17:41:58] is it possible to have the slides a little smaller? they don't fit on my screen :( it was fine before [17:42:08] lee h - didn't want to include things that are incomplete [17:42:25] changed from ppt to pdf [17:42:25] pcp = ? [17:42:49] port control protocol [17:42:53] k thx [17:43:23] stewart chesire - concerned that it leaves it with one layer deep routing \ [17:43:31] lee h - mostly by intent [17:44:04] yeah pcp /= phencyclidine [17:44:07] ɹəlɐɥʇ əʌɐp leaves the room [17:44:19] although maybe the ietf could use some [17:44:53] ? [17:45:09] randy - not cheered by the toplogy constraint [17:45:17] geir leaves the room [17:45:38] also 1812 in the router ? [17:45:47] fred - ipv4 should be off the table [17:45:57] fred I don't have a problem with ospf [17:46:09] randy is worried about rip [17:46:32] +1 to that comment [17:46:51] tom herbst - one case is uals scoped addresses and how [17:47:13] Patrik Halfar leaves the room [17:47:16] lee h we want to requirements as appropiate [17:48:10] swb leaves the room: Disconnected. [17:48:18] lorenzo I kind of despise ula in general but if we solve the topology problem with ospf then there's a boundry [17:48:47] once we have figured out how to give /64s to everyone the ula [17:48:49] works [17:48:59] lee h take it to the list [17:49:22] ole - this document is non-inovative lorenzo please write the draft. [17:49:23] dudisaki leaves the room [17:49:26] jhf leaves the room [17:49:38] done [17:49:51] t.k leaves the room [17:50:42] joelja: thanks for the good referral. It was a bit of a time travel since I read it before I heard it which is fascinating :) [17:50:46] SJX7ED15CEF leaves the room [17:50:47] Matej Gregr leaves the room: Logged out [17:50:53] Joel Jaeggli leaves the room [17:51:03] danwing leaves the room [17:51:07] m leaves the room [17:52:02] tore leaves the room [17:53:01] Tony leaves the room [17:53:06] arifumi leaves the room [17:54:20] sm leaves the room [17:57:37] WesG leaves the room [17:57:59] ꈲ leaves the room [17:58:36] SJX7ED15CEF joins the room [18:04:07] tsavo_work@jabber.org/Meebo leaves the room [18:23:21] SJX7ED15CEF leaves the room [18:27:11] rbonica leaves the room [19:24:08] jlcJohn leaves the room [19:25:00] bnsmith leaves the room [19:31:16] SJX7ED15CEF joins the room [20:06:13] Packetgrrl joins the room [21:00:48] Joel Jaeggli joins the room [21:09:44] SJX7ED15CEF leaves the room [22:16:11] Joel Jaeggli leaves the room
