draft-ietf-ipsecme-ipv6-ipv4-codes specifies new IKEv2 notification status types to better
manage IPv4 and IPv6 co-existence. The new codes improve upon the generic error code
INTERNAL_ADDRESS_FAILURE that is in RFC 7296. This document updates RFC 7296. As such,
it must be standards track.
The document was reviewed by the usual suspects of the IPsecME working group: Paul
Wouters, Valery Smyslov, MCR, Daniel Migault, Tero, and me. The review was thorough and
resulted in some changes. but consensus was rough on a few points:
* That the new notifications are always sent, regardless of whether the Initiator
did or did not request a particular type of address, and regardless of whether the
Responder was able to fulfill the request.
* It was a little controversial whether this draft ought to update 7296, or whether it
is just an extension.
The author has confirmed that he neither owns nor is aware of any IPR related to this
document.
NOTE: The need for this document came from a 3GPP use-case as reflected in the
Introduction. The group decided that the document can be useful for other IPsec uses
such as "road warrior" VPN.
