Thanks for your comments Jon. > Comments > This was my first foray into LISP, so I also read draft-ietf-lisp-rfc6830bis > and draft-ietf-lisp-introduction as ramp-up. I found all three documents to > be very readable and useful. That is good to hear. Kudos to the working group for this. > I think this document is ready to be published. I noted a few minor comments > and questions as I read through it, below. > > sec3: Map-Register contains “one or more RLOCs to reach ETR(s)”. How do you > deregister all RLOCs for an EID? You set the Record TTL in the EID-record to 0. It is stated here: > sec5: (Diagrams) It seems a bit redundant to specify the IPv4/6 and UDP > header formats here. Just refer to the RFCs. We want to be crystal clear and don’t want readers to have to shuffle documents. Those header formats are pretty etched in stone, so we don’t think we’ll have a document maintenance problem keeping it up to date. > sec5: “When a UDP Map-Reply Map-Notify” <- insert comma Fixed. > sec5.1: What about code point 7? Not assigned? Reserved? It is assigned to a non-working group draft. NAT-traversal has not gone through working group process so far. > sec6.1: “from those sites to which” should be “to those sites to which” Fixed. > sec6.1: “for the last minute” is arbitrary and should be left to the > implementation / deployment to decide IMO. Its kind of an architecture constant. > sec7.1: Have you considered using multi-hop BFD instead of RLOC probing? Yes. But there are too many LISP features we need that would not be appropriate in a more generalized BFD mechanism. We use RLOC-probing, not only for reachability testing, but to convey new RLOC changes, LISP-crypto keys, as well as differnet RLOC types. > Best regards > Jon I will publish a new version of rfc6830bis and rfc6833bis on Monday with accumilated changes from various comments. Thanks again, Dino
