Hi Reshad,

The statistics are related with igmp-mld-snooping, not only with mrouter interface.
The query is the number of  igmp query messages. The membership-report-v1/2/3 indicates the number of membership report v1/2/3 messages. The leave indicates the number of leave messages.
The pim is the number of pim hello messages. They are used to generate and maintain the entries for l2 multicast forwarding, multicast router interface, IGMP&MLD snooping membership, etc.

So I think keeping them under augment of if:interface is better.  What do you think of that?
Thanks!

Hi Hongji,

It looks like those statistics are needed only for interfaces (not for PWs) , so you could keep them under augment of if:interface, or put those stats under bridge-mrouter-interface and l2vpn-mrouter-interface-ac in the snooping-instance. My preference is for the latter.

Regards,
Reshad.

Hi Reshad,

In augment /if:interfaces/if:interface, besides mrouter related data, there are still some statistics related with igmp-mld-snooping.
If take out the whole augmentation of if:interfaces, the statistics will be lost.  What do you think of that?

augment /if:interfaces/if:interface:
    +--rw igmp-mld-snooping
       +--ro statistics
          +--ro received
          |  +--ro query?                  yang:counter64
          |  +--ro membership-report-v1?   yang:counter64
          |  +--ro membership-report-v2?   yang:counter64
          |  +--ro membership-report-v3?   yang:counter64
          |  +--ro leave?                  yang:counter64
          |  +--ro non-member-leave?       yang:counter64
