bridge multicast filtering
The bridge multicast filtering Global Configuration mode command enables filtering of multicast
addresses. To disable filtering of multicast addresses, use the no form of the bridge multicast
filtering command.

bridge multicast filtering
no bridge multicast filtering

User Guidelines
•
If multicast routers exist on the VLAN, do not change the unregistered multicast addresses
state to drop on the multicast router ports.
•
If multicast routers exist on the VLAN and IGMP-snooping is not enabled, the bridge
multicast forward-all command should be used to enable forwarding all multicast packets to
the multicast routers.
Example
In this example, bridge multicast filtering is enabled.
console(config)# bridge multicast filtering
bridge multicast address
The bridge multicast address Interface Configuration (VLAN) mode command registers MAC-
layer multicast addresses to the bridge table, and adds static ports to the group. To unregister the
MAC address, use the no form of the bridge multicast address command.
Syntax
