Description: 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 messages for this group that it receives on this interface.
What is rcIgmpCacheVersion1HostTimer?
How many seconds until the router assumes there are no more IGMPv1 hosts left for this group on this subnet; each IGMPv1 report received resets it, and while it's nonzero the router deliberately ignores IGMPv2 Leave messages for this group so it doesn't prematurely stop traffic to a v1-only host.
