Usage Scenario

A robustness variable is used to define the following values:

Number of times for sending general query messages when the MLD querier starts
Number of times for sending group-specific query messages when the MLD querier receives a Leave message
The function of this command is the same as that of the mld robust-count command used in the interface view. The configuration in the MLD view is globally valid, whereas the configuration in the interface view is valid only for the current interface. 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.

# Set the robustness variable of an MLD querier to 3 in the MLD view.
