11.2.4 MLD State Limit
You can use MLD State Limit feature to limit the number of MLD states that can be joined
to a router on a per-interface or global level. The MLD group limits feature provides pro-
tection against DoS (denial of service) attacks caused by MLD packets. Membership re-
ports exceeding the configured limits are not entered into the MLD cache and traffic for
the excess membership reports is not forwarded.
