Object
If this object and the mgmdRouterInterfaceImmedtLeave
object are set to 'true' and the
mgmdRouterInterfaceQryBefImmdLv object is set to 'false',
then the router tracks the set of hosts that have
membership of each (*,G) or (S,G). The router will only
leave immediately if there are no hosts remaining.
If mgmdRouterInterfaceImmedtLeave is also set to 'true',
then the router will only leave immediately if there are
no hosts remaining.
Explicit host tracking is only performed if all hosts are
IGMPv3/MLDv2 or IGMPv2/MLDv1. Note that tracking will only
operate correctly in the presence of IGMPv2/MLDv1 hosts if
they do not suppress Reports.
If this field is changed from 'true' to 'false' then
all host state on the interface will be removed.
If this field is changed from 'false' to 'true' then
host state will be created as membership reports are
received. Until full state has been learnt it is possible
that there could be hosts on the interface that the router
does not yet have state for, and so a leave request could
result in forwarding state being removed immediately.
