            this interface; that is, the number of times an entry for
            this interface has been added to the Cache Table.  This
            object gives an indication of the amount of IGMP activity
            over the lifetime of the row entry."

    STATUS     current
    DESCRIPTION
            "Some devices implement a form of IGMP proxying whereby
            memberships learned on the interface represented by this
            row, cause IGMP Host Membership Reports to be sent on the
            interface whose ifIndex value is given by this object.  Such
            a device would implement the igmpV2RouterMIBGroup only on
            its router interfaces (those interfaces with non-zero
            igmpInterfaceProxyIfIndex).  Typically, the value of this
            object is 0, indicating that no proxying is being done."
    DEFVAL     { 0 }

RFC 2933         Internet Group Management Protocol MIB     October 2000


    STATUS     current
    DESCRIPTION
            "The Robustness Variable allows tuning for the expected
            packet loss on a subnet.  If a subnet is expected to be
            lossy, the Robustness Variable may be increased.  IGMP is
            robust to (Robustness Variable-1) packet losses."
    DEFVAL     { 2 }
    ::= { igmpInterfaceEntry 14 }

igmpInterfaceLastMembQueryIntvl OBJECT-TYPE
    SYNTAX     Unsigned32 (0..255)
    UNITS      "tenths of seconds"
    MAX-ACCESS read-create
    STATUS     current
    DESCRIPTION
            "The Last Member Query Interval is the Max Response Time
            inserted into Group-Specific Queries sent in response to
            Leave Group messages, and is also the amount of time between
            Group-Specific Query messages.  This value may be tuned to
            modify the leave latency of the network.  A reduced value
            results in reduced time to detect the loss of the last
            member of a group.  The value of this object is irrelevant
            if igmpInterfaceVersion is 1."
