    DESCRIPTION
        "Cisco VLAN ifTable Relationship MIB lists VLAN-id and ifIndex 
         information for routed VLAN interfaces.  

         A routed VLAN interface is the router interface or sub-interface 
         to which the router's IP address on the VLAN is attached.  
         For example, an ISL, SDE, or 802.1Q encapsulated
         subinterface, or Switched Virtual Interface (SVI)."

    DESCRIPTION
        "The cviVlanInterfaceIndexTable provides a way to 
        translate a VLAN-id in to an ifIndex, so that 
        the routed VLAN interface's routing configuration 
        can be obtained from interface entry in ipRouteTable.

        Note that some routers can have interfaces to multiple
        VLAN management domains, and therefore can have multiple 
        routed VLAN interfaces which connect to different VLANs 
        having the same VLAN-id.  Thus, it is possible to have 
        multiple rows in this table for the same VLAN-id.

        The cviVlanInterfaceIndexTable also provides a way
        to find the VLAN-id from an ifTable VLAN's ifIndex."

        for the routed VLAN interface.

        Entries are created by the agent when the routed VLAN interface
        is created.  Operational status of routing does not affect
        the entries listed here.  For routing configuration please refer
        to ipRouteTable.
