[ovs-dev] Support for MCAST_Snooping

[Renuka Sachidev]

BTW, Check if the VM client is in different sub-net. I know for sure if the Machine on same sub-net it should work. That could be an issue with your setup. Send out the Test topology so that it can help other in the thread to help you.

I had developed the code slightly different from main line for V3 in the month of April and during that time I had verified the feature for IGMP MCast Snooping for V2 and V3. I had used the same test-cases to verify the Main-line code committed for IGMP V3. It should work as expected.

Verify the Aging on the bridge port to some bigger number. It had happened sometime that the VM/Machine's subscribed group would timeout.

Check on few of these commands stated below.
ovs-appctl mdb/show br-int

E.g output
 port  VLAN  GROUP     Age
    7     1  224.1.1.1   3
