Hi Frank,

I have some concerns about the proposed approach. The IPv6-in-IPv6 encapsulation may not meet the requirement C1 (which is the fundamental reason why IOAM is useful) in case the forwarding is not only determined by the DA (e.g., ECMP). Similar issue applies to IP-in-IPv6.

Besides, the encapsulation use the original dest IP address as the outer header dest IP but let the domain egress node remove the extension header, which still violates the RFC8200 (only the node with the destination address are allowed to delete the extension headers)

I don't see how such encapsulation can prevent packet leaking out of the domain as well.

In my opinion, the ultimate solution is to remove the EH limitation imposed by RFC8200 by addressing the potential negative effects for inserting/removing extension header/options within networks. I saw a recent draft from Tom Herbert and believe it's on the right track to solve the problem.

Hi folks,

Per the discussion in the last IOAM DT meeting: Could you give the PR which is to include draft-ioametal-ippm-6man-ioam-ipv6-deployment into draft-ietf-ippm-ioam-ipv6-options a quick review?
