The multicast group Internet address of the queried flows. When the 'mvrf' bit of cseFlowMcastQueryMask object in the same row is on, an appropriate value should be specified and only flows with the specified group address will be contained in the result table. If the 'groupip' bit in the associated cseFlowMcastQueryMask is cleared, this object is ignored during the query, and all flows will be considered regardless of their group address. The type of this address is determined by the value of the cseFlowMcastQueryAddrType object. The default value of this object is all zeros.
