I think you're still looking at an old version of the IPv6 Node Requirements. Check https://tools.ietf.org/html/rfc6434#section-11, specifically this bit: """ Previously, IPv6 mandated implementation of IPsec and recommended the key management approach of IKE. This document updates that recommendation by making support of the IPsec Architecture a SHOULD for all IPv6 nodes. """ This was published in December 2011. Cheers, Sander
