Hi, I've got a question regarding the relation of G-IKEv2 and GDOI.
I realized that G-IKEv2 will be the successor of GDOI and would have a question regarding backward compatibility of payloads defined for GDOI. As the underlying exchanges for the base key management changed from IKE to IKEv2 they will not be backward compatible. Nevertheless, there have been enhancements of GDOI for protocols used in the power system domain like GOOSE and Sampled Values, which lead to the definition of new payloads for the ID, SA TEK and KD payloads to accommodate the power system protocol parameters in RFC 8052. Likewise, using the same approach new payloads of the same types have been defined to distribute parameters for PTP (Precision Time Protocol) in IEC 62351-9. In general, I realized that there are similar payloads available in G-IKEv2 but I was not quite sure, if it was a design criterion to have backward compatibility for extensions/enhancements defined for GDOI to be usable also in G-IKEv2. Could you please shed some light on this?
