I agree with your opinion Mr.Satoru, I have recently uploaded a new version of the draft. https://www.ietf.org/archive/id/draft-dcn-dmm-cats-mup-03.html
The changes summary are: - CS-ID, CIS-ID should all be included inside the BGP NLRI. In my opinion, Whether to use the CS-ID as the MUP extended community or not is optional. Normally, the PE at RAN side should import DSD routes from all available services (all CS-ID) - The New added contents are: Procedure for handling underlay datapath configuration for new UE request and UE mobility in both centralized and decentralized CATS-MUP cases. I would appreciate any opinions from you about the new updates.
