Hi Mikael,

 The expire here is only for dynamic multicast group. As you say, the static configuration group won't be timeout.

 Thanks for your comments!

Hi,

Thanks for doing this work. I haven't looked at this model before, but I took a look now:

    leaf expire {
       type uint32;
       units seconds;
       mandatory true;
       description
         "The time left before multicast group timeout.";
     }

This means there is no "infinity" when it comes to this timeout. So for static configuration where no timeout exists, what should be reported here? I don't know if this is a practical problem, just something that came to mind.

Apart from that I spent 15 minutes to quick-read the document and nothing else jumped out to me... Thanks for including the appendix examples, makes it easier to understand.
