Hi Haoyu, thank you for bringing the topic of Active OAM to the discussion. As the concept of Active IOAM is introduced in the IPPM WG draft <https://datatracker.ietf.org/doc/html/draft-ietf-ippm-ioam-flags> it seems to me like adding the IPPM WG community to the discussion is the right thing to do. Please find my notes in-lined below under the GIM>> tag.
