    DESCRIPTION
        "The Extension MIB module for the CISCO-HSRP-MIB which is
        based on RFC2281.

        This MIB provides an extension to the CISCO-HSRP-MIB which 
        defines Cisco's proprietary Hot Standby Routing Protocol 
        (HSRP), defined in RFC2281. The extensions cover assigning 
        of secondary HSRP ip addresses, modifying an HSRP Group's 
        priority by tracking the operational status of interfaces, 
        etc. 

        Terminology:
        HSRP is a protocol used amoung a group of routers for the 
        purpose of selecting an active router and a standby router. 

        An active router is the router of choice for routing 
        packets.

        A standby router is a router that takes over the routing 
        duties when an active router fails, or when preset 
        conditions have been met.

        A HSRP group or a standby group is a set of routers 
        which communicate using HSRP. An HSRP group has a group 
        MAC address and a group IP address. These are the 
        designated addresses. The active router assumes  
        (i.e. inherits) these group addresses. An HSRP group is
        identified by a ( ifIndex, cHsrpGrpNumber ) pair.

        BIA stands for Burned In Address."

    DESCRIPTION
        "Each row of this table allows the tracking of one
        interface of the HSRP group which is identified by the
        (ifIndex, cHsrpGrpNumber) values in this table's INDEX clause.
        Weight(priority) is given to each and every interface tracked. 
        When a tracked interface is unavailable, the HSRP priority of
        the router is decreased. i.e cHsrpGrpPriority value assigned 
        to an HSRP group will reduce by the value assigned to
        cHsrpExtIfTrackedPriority. This reduces the likelihood 
        of a router with a failed key interface becoming the 
        active router.

        Setting cHsrpExtIfTrackedRowStatus to active starts
        the tracking of cHsrpExtIfTracked by the HSRP group. 
        The value of cHsrpExtIfTrackedRowStatus may be set 
        to destroy at any time.

        Entries may not be created via SNMP without explicitly setting
        cHsrpExtIfTrackedRowStatus to either 'createAndGo' 
        or 'createAndWait'.

        Entries can be created and modified via the management
        protocol or by the device's local management interface.

        If the row is not active, and a local management interface
        command modifies that row, the row may transition to active
        state.

        A row entry in the cHsrpExtIfTrackedTable can not be created
        unless the corresponding row in the cHsrpGrpTable has been 
        created. If that corresponding row in cHsrpGrpTable is 
        deleted, the interfaces it tracks also get deleted.

        A row which is not in active state will timeout after a
        configurable period (five minutes by default). This timeout
        period can be changed by setting cHsrpConfigTimeout."

    DESCRIPTION
        "The CHsrpExtSecAddrEntry allows creation of secondary
        IP Addresses for each cHsrpGrpEntry row.

        Secondary addresses can be added by setting 
        cHsrpExtSecAddrRowStatus to be active. The value of
        cHsrpExtSecAddrRowStatus may be set to destroy at any
        time.

        Entries may not be created via SNMP without explicitly setting
        cHsrpExtSecAddrRowStatus to either 'createAndGo'
        or 'createAndWait'.

        Entries can be created and modified via the management
        protocol or by the device's local management interface.

        If the row is not active, and a local management interface
        command modifies that row, the row may transition to active
        state.

        A row which is not in active state will timeout after a
        configurable period (five minutes by default). This timeout
        period can be changed by setting cHsrpConfigTimeout.

        Before creation of a cHsrpExtSecAddrEntry row,
        either cHsrpGrpConfiguredVirtualIpAddr or 
        cHsrpGrpLearnedVirtualIpAddr must have a valid IP Address.
        This is because a secondary ip address cannot be created
        unless the primary ip address has already been set.

        To create a new cHsrpExtSecAddrEntry row, a management 
        station should choose the ifIndex of the interface which is to 
        be added as part of an HSRP group. Also, an HSRP group number 
        and a cHsrpExtSecAddrAddress should be chosen.

        Deleting a {ifIndex, cHsrpGrpNumber} row in the
        cHsrpGrpTable will delete all corresponding
        rows in the cHsrpExtSecAddrTable.
        Deleting a primary address value in the cHsrpGrpEntry row
