Analysis

• The ACL rule is incorrectly configured.

• The multicast group policy is not correctly applied.

• The function of dropping unknown multicast data is not enabled, so unknown multicast data is

flooded.

Solution

1. Use the display acl command to check the configured ACL rule. Make sure that the ACL rule

conforms to the multicast group policy to be implemented.

2. Use the display this command in IGMP snooping view or in the corresponding interface view to

check whether the correct multicast group policy has been applied. If not, use the group-policy or

igmp-snooping group-policy command to apply the correct multicast group policy.

3. Use the display current-configuration command to determine whether the function of dropping

unknown multicast data is enabled. If not, use the drop-unknown command to enable the function

of dropping unknown multicast data.
