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 check whether the function of dropping
unknown multicast data is enabled. If not, use the igmp-snooping drop-unknown command to
enable the function of dropping unknown multicast data.
