Enabling IPv6 multicast group replacement

This feature enables the switch to replace an existing group with a newly joined group when the
number of groups exceeds the upper limit. This feature is typically used in the channel switching
application. Without this feature, the switch discards MLD reports for new groups, and the user
cannot change to the new channel.
Configuration restrictions and guidelines
When you enable IPv6 multicast group replacement, follow these guidelines:
•
This configuration takes effect only on the multicast groups that the port joins dynamically.
•
You can enable this feature globally for all ports in MLD-snooping view or for a port in interface
view. For a port, the port-specific configuration takes priority over the global configuration.
