MLD Snooping Robustness Value
The robustness variable allows you can tune to reflect expected packet loss on a con-
gested network. If a network is expected to be lossy, you can increase the robustness
variable to increase the number of times that packets are resent.

MLD snooping querier, a host returns the report message as many as the specified ro-
bustness variable.

MLD Snooping Querier Configuration
MLD snooping querier should be used to support MLD snooping in a VLAN where PIM
and MLD are not configured.
When the MLD snooping querier is enabled, the MLD snooping querier sends out periodic
general queries that trigger membership report messages from a host that wants to re-
ceive multicast traffic. The MLD snooping querier listens to these membership reports to
establish appropriate forwarding.
