Yes....there were many IPv6 capable devices without IPsec for many years. One of the comments made in the thread of Feb 2008 was that MUST or SHOULD wouldn't make much difference in getting implementations to appear. http://www.ietf.org/mail-archive/web/ipv6/current/msg09230.html > > Question: Does "requiring IPsec support in all other devices" mean > "complying with RFC 4301"? If that's the case, you're also requiring > those devices to support IKEv2. The intent right now is to add the following specifications for IPsec support • IPsec-v3 [RFC4301, RFC4303, RFC4302] * • IKE version 2 (IKEv2) [RFC5996 (obsoletes RFC 4306), RFC4718] * • ISAKMP [RFC2407, RFC2408,RFC2409] I have been seeing more shipping IKEv2 implementations in past few years and do believe most newer devices follow IPsec-v3 specs. Again, this is something authors would like to hear input on to make sure this is right thing to specify across all devices, regardless of whether IPsec will be mandatory or optional. > If that's intentional, I think you should make it explicit...
