The value of the object sdpBndIgmpSnpgCfgRobustCount
specifies the value of the Robust count.
This object allows tuning for the expected packet loss on this SDP.
If a SDP is expected to be lossy, the Robustness Variable may be
increased. IGMP snooping is robust to (Robustness Variable-1) packet
losses.
The value of this object is only meaningful when the value of
sdpBndIgmpSnpgCfgSendQueries is 'enabled(1)'.
