Version 1 Host Timer
— The time 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 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.
