Hi, New draft: https://datatracker.ietf.org/doc/draft-mcb-intarea-icmpv6-loopback/
We have posted a new draft that proposes two new ICMPv6 message types: Loopback Request and Reply. ICMPv6 Loopback is very similar to Echo, except that after a Loopback Request is sent, its corresponding Reply includes as much of the IPv6 Loopback Request packet as possible, including the IPv6 header and IPv6 extension headers and options if they are present. We believe that ICMPv6 Loopback can be very useful for returning IPv6 options that were included in Request packet back to the sender, including for example sending IOAM [RFC 9197] data from the Request back to the sender, sending the SRH [RFC 8754] of the Request back to the sender, as well as for in-progress / future protocols such as draft-filsfils-spring-path-tracing and draft-kumar-ippm-ifa. We would be happy for feedback, as well as suggestions about whether the INT-AREA WG is the right place to discuss this draft. Cheers, Tal. _______________________________________________ Int-area mailing list Int-area@ietf.org https://www.ietf.org/mailman/listinfo/int-area
