[07:07:51] <stefan.winter> Hi, this is radext at IETF80.
[07:08:12] <stefan.winter> /topic radext at IETF80
[07:08:30] <stefan.winter> The days of IRC are truly gone :-(
[07:08:44] <jpdionne> sad
[07:10:56] <stefan.winter> Dan announces Bernard is now AIB chair and needs to step down as radext chair.
[07:11:42] <stefan.winter> Co-chair position is open, announcement will probably be made early next week.
[07:14:19] <stefan.winter> Agenda bashed, one item moved to earlier (presenter Jiang)
[07:14:32] <stefan.winter> 3575 errata being discussed.
[07:14:51] <stefan.winter> Should it update 2868?
[07:15:05] <stefan.winter> Basic underlying question: how should we do Tunnel-Type allocations
[07:16:29] <stefan.winter> Designated expert vs. RFC. 3575 states Designated Expert, but then lacks exception text in section 2.1
[07:17:34] Linus Nordberg joins the room
[07:19:53] <stefan.winter> Dan: either take stricter one, or youngest one. In any case it needs to be documented.
[07:21:18] <stefan.winter> Show-hands: accept errata, should update 2868?
[07:21:29] <Alan DeKok> yes
[07:21:41] Klaas Wierenga joins the room
[07:21:52] <stefan.winter> 10 : 0 *for* accepting errata, will be taken to the list
[07:22:07] <stefan.winter> Next IANA issue: NAS-Port-Type
[07:24:28] <stefan.winter> (and WiMAX WiFi vs. normal WiFi)
[07:27:29] <stefan.winter> WG is reading the emails regarding the issue
[07:28:54] <stefan.winter> Proposition to have one allocation: "WiMAX" and have VSAs for differentiating what's below.
[07:29:36] <stefan.winter> Nobody disagrees; request to be denied probably; will be taken to the list.
[07:31:12] <stefan.winter> moving to IPv6 portion of agenda
[07:33:00] <stefan.winter> Presentation on "Attributes for 6rd"
[07:35:56] <stefan.winter> presenter is going through slides
[07:38:21] <stefan.winter> How many IPv4 BRs can there be? Answer: by claculating from attribute length.
[07:38:42] <stefan.winter> Can there be more than one attribute? Answer: yes.
[07:39:02] <Alan DeKok> We use extended attrs, and put the "struct" into TLVs!
[07:40:35] <stefan.winter> don't want to delay publication; not waiting for extended attrs.
[07:40:50] <stefan.winter> for lack of alternative, seems as good as it gets.
[07:41:50] <stefan.winter> Presentation: RADIUS Issues in IPv6 deployments
[07:42:05] <stefan.winter> (Presenter: Jacni Qin)
[07:42:47] <stefan.winter> Presenter is going through slides...
[07:42:59] <stefan.winter> "Issues encountered"
[07:44:17] <stefan.winter> "Possible Solutions"
[07:46:40] <stefan.winter> "Next step"
[07:47:18] <stefan.winter> Bernard regarding #3 (separate accounting)
[07:48:59] <stefan.winter> First about #2 (network or host on CPE): can existing attributes be re-used? Need to find distinction between use cases.
[07:49:07] <stefan.winter> Discussion later in the meeting
[07:49:15] <stefan.winter> Now about #3.
[07:50:17] <stefan.winter> Alan: interpretation of octet values tend to be "global", not protocol-specific
[07:52:10] <stefan.winter> Jouni Korhonen: in mobile networks, using the existing attribute - but also extra attributes (VSAs)
[07:53:00] <stefan.winter> Bernard: how do you do IPv6 specific accounting? They don#t care about distinction (time-based tariffs).
[07:54:13] <Alan DeKok> <raises hand>
[07:55:47] <stefan.winter> Alan notes Multi-Session-Id is used sometimes
[07:56:06] <stefan.winter> So, two different Accounting Sessions, linked together with one Multi-Session-Id.
[07:58:58] <stefan.winter> Question: is issue #3 worth being worked on in WG?
[08:01:24] <stefan.winter> two in favor, none against. Will be taken to the list.
[08:01:35] <stefan.winter> Presenter stresses that this is important for deployment.
[08:02:42] <stefan.winter> VSA can be used immediately, until WG produces result.
[08:04:07] <stefan.winter> Presentation: RADIUS attribs or Dual Stack Access
[08:04:13] <stefan.winter> ... for ...
[08:04:29] <stefan.winter> (Presenter: Leaf Yeh)
[08:04:37] <stefan.winter> Slide: Deployment Scenario
[08:05:33] Bjoern A. Zeeb leaves the room
[08:07:13] <stefan.winter> SLide: User-Type
[08:08:03] <stefan.winter> Slide: User-Type (2)
[08:10:05] <stefan.winter> Bernard: there is also Framed-IPv6-Route, and IPv6-Route-Information
[08:11:30] <stefan.winter> Slide: User-Type (3)
[08:12:36] <stefan.winter> Slide: Traffic Statistics Attributes
[08:13:37] <stefan.winter> Slide:  ... (2)
[08:14:34] <stefan.winter> Slide: Proposal
[08:15:45] <stefan.winter> same issue about split accounting
[08:16:07] <stefan.winter> will be discussed on list
[08:16:56] <stefan.winter> Bernard: regarding User-Type - there might be something in here that can't be addressed with existing RADIUS attribs.
[08:24:54] <stefan.winter> it is still unclear what the exact usage case for the User-Type attribute would be.
[08:25:02] <stefan.winter> Bernard suggests to take to the list.
[08:26:59] <stefan.winter> Discussion of Issue: Framed-IPv6-Route
[08:27:08] <stefan.winter> (regarding Trac ticket #69)
[08:28:57] <stefan.winter> Discussion regarding trac #71
[08:29:13] <stefan.winter> nobody had substantial comments regarding #69
[08:30:04] jpdionne leaves the room
[08:30:05] jpdionne joins the room
[08:30:24] <stefan.winter> need the draft to explain the exact differences between the attributes.
[08:30:37] <stefan.winter> Q: anyone implements these attributes in equipment?
[08:33:03] Bjoern A. Zeeb joins the room
[08:33:03] <stefan.winter> Leaf is looking up attributes and implementation.
[08:33:59] <stefan.winter> Jouni: impleneted IPv6, but they ignore the attributes here.
[08:34:17] <stefan.winter> Beranrd: How do you get the information for the RA into the NAS?
[08:34:46] <stefan.winter> Jouni: Either with Framed-IPv6-Prefix (to the NAS) - there is only one prefix.
[08:34:58] <stefan.winter> NAS distributes from there.
[08:35:28] <stefan.winter> Beranrd: do you implement More-Specific-Routes - A: No.
[08:39:00] <stefan.winter> Bernard voices a possible distinction between the attributes; will be brought to the list.
[08:39:22] <stefan.winter> Presentation on Crypto-Agility reqs
[08:39:27] <stefan.winter> Slide: Status
[08:41:59] <stefan.winter> Does encryption of entire packet obsolete keywrap?
[08:42:18] <stefan.winter> keywrap seems to be RADIUS hop-by-hop, just like transport encrpytion
[08:42:35] <stefan.winter> keywrap can stil do some good if no packet encryption is present.
[08:43:40] <stefan.winter> Dan: draft-zorn-keywrap is VSA space, IESG suggested to reconcile if crypto-agility suggests so.
[08:45:24] <stefan.winter> Issue #90
[08:45:29] <stefan.winter> no comments from audience
[08:46:10] <stefan.winter> Slide: Next Steps
[08:46:38] <stefan.winter> going to üpresent on TLS now.

[09:22:23] <stefan.winter> Discussion is: is this deployer-friendly?
[09:22:48] <stefan.winter> Alan: No choice anyway, we *are* running out of attrib space.
[09:25:28] <stefan.winter> Alan: new specs coming out of radext should be heavily encouraged to use this new format.
[09:25:58] <stefan.winter> 7 people read draft
[09:26:34] <stefan.winter> Dan: nice to have this spec, but we shouldn't hold back issue of other drafts for it.
[09:26:52] <stefan.winter> Meetings adjourned.
