I support adoption of this draft.

I have reviewed draft-acee-netmod-rfc8022bis-02, and ask that the following comments be considered after the document has been adopted:

1. Does the draft still require a normative reference to 6020? Given that the modules are all YANG revision 1.1 perhaps this isn't required any more?

2. In appendix D:
i) it would be better if the YANG library example was updated to match the model in YANG library bis (e.g. use a modules path rather than modules-state). ii) I think that it should state that this is an example of the data that may be received by reading from the operational state datastore. iii) In the example, the "interface-state" tree output should be merged in with "interfaces" so illustrate the combined NMDA view.

3. ipv6 prefix list.
When I had first looked at combining the existing RFC YANG modules to NMDA, I came up with a slightly different way of modelling IPv6 prefixes, splitting "no-advertise-prefix-list" separately from the "advertised prefixes".

E.g. if your draft the tree output is:

      +--rw prefix-list
         +--rw prefix* [prefix-spec]
            +--rw prefix-spec           inet:ipv6-prefix
            +--rw (control-adv-prefixes)?
               +--:(no-advertise)
               |  +--rw no-advertise?         empty
               +--:(advertise)
                  +--rw valid-lifetime?       uint32
                  +--rw on-link-flag?         boolean
                  +--rw preferred-lifetime?   uint32
                  +--rw autonomous-flag?      boolean

Perhaps you could consider this structure instead (I can send you the actual YANG if it helps):

       +--rw no-advertise-prefix-list
       |  +--rw prefix* [prefix-spec]
       |     +--rw prefix-spec     inet:ipv6-prefix
       |     +--rw (control-adv-prefixes)?
       |        +--:(no-advertise)
       |           +--rw no-advertise?   empty
       +--rw prefix-list
          +--rw prefix* [prefix-spec]
             +--rw prefix-spec           inet:ipv6-prefix
             +--ro valid-lifetime?       uint32
             +--ro on-link-flag?         boolean
             +--ro preferred-lifetime?   uint32
             +--ro autonomous-flag?      boolean

Thanks,
