We have two different designs of MVR - L2 MVR & L3 MVR.
The Key difference for those two are the multicast data received on the clients.
For example, please find the basic MVR configuration on the switch.
L2 MVR design
When the switch enables MVR function and the status becomes "Active", the MVR receiver port will join the MVR VLAN as member automatically.
Once the client joins the multicast group, the client could receive the multicast data with MVR VLAN tagged (trunk mode) or untagged (hybrid mode).
Models: ECS4620 series, ECS4510 series, ECS4120 series, ECS4100 series, ECS4110 series, ECS4210 series, ECS3510-28T/52T, ES3528Mv2, ES3510MA
L3 MVR design
MVR receiver port will NOT join the MVR VLAN as member automatically when the MVR function is active.
When the client joins the multicast group, the multicast data with MVR VLAN will replace the VLAN tag to client VLAN and forward to the port.
Models: ECS4660-28F, ECS4610-24F, ECS4610-26T/50T
