The mld require-router-alert command enables an interface to discard the Multicast Listener Discovery (MLD) messages that do not contain Router-Alert options in IPv6 headers.
The undo mld require-router-alert command restores the default configuration.
By default, the interface accepts and processes the MLD messages that do not contain Router-Alert options in IPv6 headers.

Usage Scenario
The function of this command is the same as that of the require-router-alert command used in the MLD view. The system prefers the configuration in the interface view. The configuration in the MLD view is used only when the configuration in the interface view is not done.
