Hi all, Thanks for the nice feedback received at IETF118, and also thanks for the idea of using 4o6 on that peculiar use case. The existing rfc7341 details pretty well how to deal with IPv4 DHCP in cooperation with DHCPv6 Relay Agents. The way forwards for solving the Fronthaul topology is to implement the 4o6 encapsulation at the first hop switch rather than in the Client. As suggested by Suresh, it may be an option to extend the Relay Agent functionality by hosting also the 4o6 encapsulation. Such Relay Agent would be able receiving also plain DHCPv4 request so that the Client would not need to be aware that it’s a 4o6 scenario. We will start describing the use case in the draft, including how it applies to rfc6621 LDRA. We would appreciate receiving feedbacks on the proposal and also how to proceed, that is either by continuing with a separate draft or proposing an extension to rfc7341. Best regards, Claudio, Jari, Mirja
