Configuring an IPv6 multicast group policy
About IPv6 multicast group policies
This feature enables the Layer 2 device to filter MLD reports by using an ACL that specifies the IPv6 multicast groups and the optional sources. It is used to control the IPv6 multicast groups that receiver hosts can join. This configuration takes effect on the IPv6 multicast groups that ports join dynamically.
In an IPv6 multicast application, a host sends an unsolicited MLD report when a user requests an IPv6 multicast program. The Layer 2 device uses the IPv6 multicast group policy to filter the MLD report. The host can join the IPv6 multicast group only if the MLD report is permitted by the IPv6 multicast group policy.
