Hi Dhruv

Thanks for comments, I can change it in the next draft.
There was just too many question on how the packet looks like and I felt drawing the bytes could help.

Just to ensure you are looking for something like  below:
Note: the questions I am getting is to give a rough view of how the packet looks in different cases.

Common header
Lsp object with plsp-id = 1, Root= A, tree-id=y, instance-id = L1
Association object
P2MP SR policy ID with root=A, tree-ID=y
P2MP SR Policy name = “name”
…
CCI with cc-id =x , label 0
              Path-attribute ero-path id =1 , backup-path id =2
              SR-ERO ipv4-addr = NHD1, SID= d1

Etc…

Thanks
Hooman

Hi,

Just one quick comment! I remember making this point earlier as well, and if the WG disagrees please let me know!

I am not a fan of the format used by the examples in this I-D (which are in the form of PCEP packet structures)  - https://datatracker.ietf.org/doc/html/draft-ietf-pce-sr-p2mp-policy-03#section-7.2
It might be useful for someone debugging (well we also have tools that do that way better and show results in a much more friendly way), but not for a general reader of an RFC.

You will also note that this is not the usual style followed in the PCE WG document. P2MP RFCs have examples in past, my request would be to follow the same style and not to deviate -
https://www.rfc-editor.org/rfc/rfc8623.html#section-6.6
https://www.rfc-editor.org/rfc/rfc8306.html#section-3.10

Thanks!
Dhruv (as a WG participant)

Abstract:
   SR P2MP policies are set of policies that enable architecture for
   P2MP service delivery.  This document specifies extensions to the
   Path Computation Element Communication Protocol (PCEP) that allow a
   stateful PCE to compute and initiate P2MP paths from a Root to a set
   of Leaves.
