[Q] IGMPv3 ?

Dear Seniors

I guess below code is for IGMPv3 source filtering feature.
Am I correct ?

~ns/tcl/mcast/ns-mcast.tcl

#Node instproc join-group-source { agent group source } {
#        $self instvar Agents_ mrtObject_ replicator_
#        set group [expr $group]
#        ## send a message for the mcastproto agent to inform the mcast protocols
#        $mrtObject_ join-group $group $source
#        lappend Agents_($source:$group) $agent
#        if [info exists replicator_($source:$group)] {
#                $replicator_($source:$group) insert $agent
#        }
#}

#Node instproc leave-group-source { agent group source } {
#        $self instvar replicator_ Agents_ mrtObject_
#        set group [expr $group]
#        if [info exists replicator_($source:$group)] {
#                $replicator_($source:$group) disable $agent
#        }
#        $mrtObject_ leave-group $group $source
#}
