+
+## Feature Overview
+
+  **Problem**: In Sonic L3 multicast, if Vlan has 3 ports and if there is IGMP receiver present on only one port, multicast traffic will be forwarded to all members of the VLAN irrespective of the port where the IGMP join is received. This is because L3 multicast in Sonic doesn’t store port level information and the limitation is tied to the way SAI API’s are defined for IP multicast and L2 multicast. 
+
+  So, today we support either L3 PIM or IGMP snooping on a given VLAN. In other words, we cannot do L3 switching and L2 switching for the same IPMC group. 
+
+  **Solution**: As IGMP snooping holds VLAN port level information where the IGMP joins are received, the solution is to converge L3 multicast and IGMP snooping VLAN ports to derive ports where the multicast traffic to be forwarded instead of flooding on all member ports of the Vlan.
+
+  **Expected behavior changes**: 
+   - When a user configures IGMP snooping and PIM on the same VLAN, traffic disruption happens as we are flushing existing entries to converge OIFs from the beginning.
+   - To avoid disruption of traffic, the suggestion is to configure IGMP snooping and PIM on VLAN even before starting the traffic.
+   - Since we don’t share IPMC resources when both L3 multicast and IGMP snooping are enabled on VLAN, each L3 multicast entry will make use of one IPMC resource, so, there will be change in the scaling as per the chipset supported IPMC resource.
+
+## 1 Test Focus Areas
+
+  - This Test plan covers the validation of the multicast traffic forwarding in a Vlan (with multiple member ports) in which L3 multicast (PIM) and IGMP Snooping are configured. 
+
+### 1.1 CLI Testing 
+No new CLI added as a part of this feature enhancement.
+
+### 1.2 Functional Testing
+
+  - Verify that user can enable PIM SSM and IGMP Snooping on same Vlan interface.
+  - Verify that with PIM SSM and IGMP snooping enabled on vlan interface (in default VRF), multicast traffic is only forwarded to the port on which the IGMPv3 Join is received/ IGMPv3 Host learned.
+  - Verify that with PIM SSM and IGMP snooping enabled on vlan interface (in User VRF), multicast traffic is only forwarded to the port on which the IGMPv3 Join is received/ IGMPv3 Host learned.
+  - Verify multicast traffic forwarding in vlan with PIM SSM and IGMP snooping enabled while IGMPv3 host/Join learned on one member port, and a new port is added into the Vlan but no IGMPv3 host/Join learned on that new port.
+  - Verify multicast traffic forwarding in vlan with PIM SSM and IGMP snooping enabled when the member ports in the vlan are port channel interface.
+  - Verify multicast traffic forwarding in vlan with PIM SSM and IGMP snooping enabled after shut no shut on the member ports of the vlan on which IGMPv3 Hosts/Joins are learned. 
+  - Verify multicast traffic forwarding in vlan with PIM SSM and IGMP snooping enabled when different member ports in Vlan has IGMPv3 hosts learned with different source address.
+  - Verify multicast traffic forwarding in vlan with PIM SSM and IGMP snooping enabled while IGMPv3 host/Join learned on one member port, and IGMP Snooping is enabled and disabled on Vlan Interface.
+  - Verify multicast traffic forwarding in vlan with PIM SSM and IGMP snooping enabled while IGMPv3 host/Join learned on one member port, and PIM SSM is enabled and disabled on Vlan Interface.
+  - Verify multicast traffic forwarding in vlan with PIM SSM and IGMP snooping enabled while IGMPv3 host/Join learned on all member ports, and then IGMPv3 Leave is sent on all ports except one port, traffic should get forwarded to that port only.
+  - Verify multicast traffic forwarding in member ports of vlan with PIM SSM enabled first and IGMP snooping is enabled while traffic is forwarding (traffic disruption is expected, but make sure traffic is forwarded successfully after that).
+  - Verify multicast traffic forwarding in member ports of vlan with PIM SSM and IGMP snooping is enabled first on Vlan interface and then ports are added to the Vlan Interface.
+  - Verify multicast traffic forwarding in member ports of vlan with PIM SSM and IGMP snooping is enable after Warm boot.
+  - Verify multicast traffic forwarding in member ports of vlan with PIM SSM and IGMP snooping is enable after fast boot.
+  - Verify multicast traffic forwarding in member ports of vlan with PIM SSM and IGMP snooping is enable after reboot.
+
+### 1.3 Scalability Testing
+  - Verify max supported mroute entries in a Vlan with PIM SSM and IGMP snooping on the Vlan interface.
