IPv6 multicast group policy does not work
Symptom
Hosts can receive multicast data from IPv6 multicast groups that are not permitted by the IPv6 multicast group policy.
Solution
To resolve the problem:
Use the display acl ipv6 command to verify that the configured IPv6 ACL meets the IPv6 multicast group policy requirements.
Use the display this command in MLD-snooping view or in interface view to verify that the correct IPv6 multicast group policy has been applied. If it is not correctly applied, use the group-policy or mld-snooping group-policy command to apply the correct IPv6 multicast group policy.
Use the display mld-snooping command to verify that dropping unknown IPv6 multicast data is enabled. If it is not enabled, use the mld-snooping drop-unknown command to enable dropping unknown IPv6 multicast data.
If the problem persists, contact Hewlett Packard Enterprise Support.
