Version 1 Host Timer - The time (in hh:mm:ss) remaining until the local router assumes that there
are no longer any IGMP version 1 members on the IP subnet attached to this interface. When an
IGMPv1 membership report is received, this timer is reset to the group membership timer. While this
timer is non-zero, the local router ignores any IGMPv2 leave messages for this group that it receives
on the selected interface. This field is displayed only if the interface is configured for IGMP version 1.
Version 2 Host Timer - The time (in hh:mm:ss) remaining until the local router assumes that there
are no longer any IGMP version 2 members on the IP subnet attached to this interface. When an
IGMPv2 membership report is received, this timer is reset to the group membership timer. While this
timer is non-zero, the local router ignores any IGMPv1 and IGMPv3 leave messages for this group
that it receives on the selected interface. This field is displayed only if the interface is configured for
IGMP version 2.
