Hi Tony,

I agree with you. Will try to add some descriptions on the fragmentation issue.

Best Regards,
Xiao Min

good observation. As individual I think the IOAM draft is pretty interesting work but yes, fragmentation is an issue we need to talk about in this context

Hi,
For IOAM data in BIER, I want to point out that we should use a generic header format that can be used for BIER/MPLS/IPv6. The same extension mechanism can be used for other purposes like fragmentation/security, etc.
This was discussed in https://www.ietf.org/archive/id/draft-zzhang-intarea-generic-delivery-functions-02.txt, and was mentioned in slide #6 of https://datatracker.ietf.org/meeting/112/materials/slides-112-bier-03-bier-slicing-and-differentiation-00 in IETF112 BIER session.
Thanks.
