Hi Benjamin,

I have addressed your comments and post the latest version as draft-ietf-pim-igmp-mld-snooping-yang-18.  Thanks a lot!

Btw, The last-reporter shows one IGMP host, which has sent either an unsolicited IGMP Join or IGMP Report for that particular group.   Most vendors have it implemented.

BR/Hongji

Hi Hongji,

Yes, that looks like it will work quite well in terms of indicating what behavior will result.  (I do not have enough YANG experience to comment on whether this usage of a "type empty" is conventional, but trust that the responsible AD will get additional review if needed.)

Thank you,

Ben
