    DESCRIPTION
           "This MIB contains information related to Virtual 
           Routing and Forwarding (VRF).
           
           VRF is a mechanism by which a single device can provide
           independent routing instances. This allows customers to 
           virtually isolate network traffic, and also use overlapping
           IP addresses.

           Layer3 or routed interfaces in the system will belong to
           one VRF at a time. The datapath forwarding logic uses the
           VRF membership of the input interface to determine a
           specific forwarding table to use for routing the traffic.

           VRF can also be used to isolate management traffic from
           the rest of the data plane traffic.
           
           This MIB module provides the following pieces of
           information:
               * A table of all VRFs configured in the system
               * A table that contains the VRF membership information
               for all routed interfaces in the system by sparsely
               augmenting the ifTable."
