mgmdRouterCacheVersion1HostTimer

The time remaining until the local router will assume that
there are no longer any IGMP version 1 members on the IP
subnet attached to this interface.  Upon hearing any IGMPv1
Membership Report, this value is reset to the group
membership timer.  While this time remaining is non-zero,
the local router ignores any IGMPv2 Leave Group messages and
some types of IGMPv3 and MLDv2 Membership Report messages
for this group that it receives on this interface.
              
The value will be zero for entries for statically
configured memberships (regardless of any matching learned
memberships).
