It looks like the conversation about this topic has died down. Can you
please close the discussion and tell us if the WG reached a consensus and
what that is?

I care.
It seems to me that we have registries where we have different documents
allocating values from the same space. This makes sense: we need to coordinate
things.

I simply think that the specifications are not complete without
guidance on how to use/assign the unused bits. I
ink it is the other way round – they look at drafts/RFCs and

Hi Les
Hi Les,
I would like to share my personal experience that when debugging network
issues say using wireshark or tcpdump often dissectors only decode what is
in IANA registry. Anything beyond they print as hex.
Sure if someone needs to decode it he or she will find an RFC where all

In your review of draft-ietf-lsr-isis-srv6-extensions you requested the authors
