Use this command only on MLDv1 and MLDv2 interfaces to which one host is connected.
If there is more than one host connected to a network segment through the same inter-
face, and a certain host receives a done message, the router will remove all hosts on the
interface from the multicast group. The router will lose contact with the hosts that should
remain in the multicast group until they send join requests in response to the router's next
general query.
11.1.7
MLD Proxy
MLD Proxy enables this L3 switch to issue MLD host messages on behalf of hosts that
the switch discovered through standard MLD interfaces. The switch acts as a proxy for its
hosts.
MLD Proxy can only work in a simple tree topology; where traffic is distributed to explicit
upstream and downstream. You need to manually designate upstream and downstream
interface on MLD proxy switch. There are no multicast routers within the tree and the root
of the tree is expected to be connected to a wider multicast infrastructure.
The MLD proxy-enabled switch can deliver multicast traffic to the downward LANs or di-
rect hosts without performing complex multicast routing protocol.
MLD proxy-service should not be used when configuring interfaces enabled for MLD in
association with a multicast-routing protocol, otherwise the behavior will be undefined.
