Re: [IPsec] Please comment on Steve's P2P draft

I read the draft yesterday. I wasn't surprised. That in itself was a surprise. It's exactly what I thought the problem is from the beginning. There was no big mystery requirement that I didn't understand. The only thing I found weird was the belief that RFC4301 SPD configuration had to be "h

On Chris' new use case, I don't think that's a new use case. I think it's a requirement that spans all the use cases. The solution must be able to handle network topology changes. But we're not into requirements yet. Use cases first. Thanks, Steve > -Original Message- > From: Ulliott, Ch

Of course, you're right. The acronym DMVPN makes this a very bad choice. Thanks for pointing that out. I'll throw out a few ideas here: Dynamic Direct VPN (DDVPN) Shortcut VPN (SVPN) Dynamic Scalable VPN (DSVPN) Dynamic Efficient VPN (DEVPN) Other ideas or comments on these are most welcome. Th

Classification:UNCLASSIFIED Good catch! I've also thought of an additional use case, as I extend / change a network within a data centre etc, it would be helpful if the crypto gateway could learn of the new networks (through routing perhaps) and make them available through the encrypted tunne

Steve, I do not think changing the name to "Dynamic Mesh VPN" is a good idea. The first thing that is going to happen is that it is going to be shortened to "DMVPN" and then we have conflict with Cisco DMVPN, which would be confusing and also "DMVPN" is a registered trademark. It would be best t

http://trac.tools.ietf.org/wg/hip/trac/ticket/30 This ticket states: "Interactions with complex SPDs may result in weird effects. Need some suggested text to clear this issue." I believe this tracker item is drawn from Robert Moskowitz's IETF 80 presentation. Note that for RFC 5202, there was

http://trac.tools.ietf.org/wg/hip/trac/ticket/32 This issue requests to add normative text on when to have a domain identifier. I believe that this could be simply addressed by adding this statement to section 5.2.9: "A host MAY optionally associate its Host Identifier with a single Domain Id
