When you enter the SSM Range ensure that the upstream router has the same range, else the multicast stream
would be dropped.
Dynamic Multicast Optimization
When multiple clients are associated to an AP and when one client is subscribed for a multicast stream, all the
clients associated to the AP receive the stream, as the packets are directed to the multicast MAC address. To
restrict the multicast stream to only the subscribed clients, DMOsends the stream to the unicast MACaddress
of the subscribed clients. DMOis currently supported for both IPv4 and IPv6.
In the WebUI
You can configure the IPv6 DMO feature using the WebUI or CLI.
