Enabling dropping unknown multicast data
Unknown multicast data refers to multicast data for which no forwarding entries exist in the IGMP
snooping forwarding table. When the IGMP snooping-enabled router receives such multicast traffic, one
of the following occurs:
• If the function of dropping unknown multicast data is disabled, floods unknown multicast data in the
VLAN that the unknown multicast data belongs to.
• If the function of dropping unknown multicast data is enabled, drops all received unknown multicast
data.
The following matrix shows the feature and the MSR router compatibility:
