User Guidelines
If multicast routers exist on the VLAN, do not change the unregistered multicast addresses state to drop on the
switch ports.
If multicast routers exist on the VLAN and IGMP-snooping is not enabled, the
bridge multicast forward-all
com-
mand should be used to enable forwarding all multicast packets to the multicast switches.
