robust-value: IGMP querier robustness variable, with an effective range of 2 to 5. The IGMP robustness 

variable determines the default number of general queries the IGMP querier sends on startup and the 

number of IGMP group-specific queries the IGMP querier sends upon receiving an IGMP leave 

message.  

Use the igmp robust-count command to configure the IGMP querier robustness variable on the 

current interface.  

Use the undo igmp robust-count command to restore the system default.  

By default, the IGMP querier robustness variable is 2.
