[13:38:40] <Wassim M. Haddad> one slide only
[13:39:47] <weiyinxing> lisp-sec: a bit of confusion, why not reusing mature security mechanisms, e.g. DTLS, IPSEC, but reinventing a new mechanism.
[13:44:08] <Wassim M. Haddad> LISP Deployment
[13:47:02] Alex Petrescu joins the room
[13:47:38] <Alex Petrescu> hey there
[13:47:48] <Joel> Weiyinxing: The short answer is that DTLS does not address the threats that need to be dealt with. For a longer, and better supported, answer, please ask on the email list.

[13:49:19] <weiyinxing> Interesting answer, thanks.

[14:22:29] Dino joins the room
[14:23:49] <Dino> Does anyone have any questions on any of the new presentations?
[14:24:01] <Dino> we can try to answer you here
[14:28:58] <Ralph Droms> Dino - I'll ask a variant of a question I've asked before: what are the address uniqueness requirements, especially if the xTRs (and, presumably, the nodes sending traffic through the xTRs) are behind NATs?
[14:29:59] <Dino> the xtr will get a private address from the NAT, just as it does today. When the NAT translates any packets originated by the xTR the source will be translate to a global address
[14:30:26] <Dino> that global address it the RLOC that the RTR needs to know about so it can encapsulate packets to the global RLOC that is translated back
[14:30:51] <Dino> all the EIDs that are behind the xtr are registered in the mapping database with the locator-set equal to the RTRs supporting the site
[14:30:56] <Dino> did that help?
[14:31:14] <Ralph Droms> Yes, thanks. The EID spaces behind the two xTRs have to be disjoint, right?
[14:31:33] <Ralph Droms> Those EIDs are carried without NAT translation?
[14:32:00] <Dino> no, that is a single EID-prefix behind both because it is a LISP multi-homed site
[14:32:21] <Dino> right, EIDs are carried without translation because they are never seen by the core (they are the inner header)
[14:34:13] <Ralph Droms> Oh, OK, I missed that assumption.
[14:38:11] <Dino> we had LISP working at our houses, behind NATs for a few years, but we have to pinhole UDP port numbers
[14:38:12] <Wassim M. Haddad> LISP-DDT Database Transfer
[14:38:38] <Dino> we know want xtrs (LISP mobile-nodes) to roam between Starbucks and you don't want to ask the Burista to configure pinholes ;-)
[14:41:05] <Dino> hence the nat-traversal design
[14:44:34] <Wassim M. Haddad> LISP based single-source multicast
