The MIB module for provisioning and managing network
virtualization features. 

This module provides manageability for VRF, VRF-Lite and 
vNET. VRF stands for Virtual Routing and Forwarding. VRF 
is an extension of IP routing that provides multiple routing
instances. VRF provides independent routing instances and
hence the same or over-lapping addresses can be used without
conflicting each other. VRFs are used in conjunction with 
MPLS VPN to provide traffic separation between multiple VPN
customers. 

A VRF-Lite enabled device implements VRFs and does not require
MPLS for end to end communication. Instead of using MPLS
labels, VRF-Lite uses the interfaces to distinguish routes for
different VPNs. VRF-Lite forms virtual packet-forwarding tables
by associating one or more interfaces with each VRF, and
interfaces cannot belong to more than one VRF at any time.

VRF-Lite is an IP based hop-by-hop virtualization mechanism and
it involves complex configuration of every hop in the network.
vNET, virtual network, is also an IP based hop-by-hop mechanism
that can provide end-to-end virtualization of the network. vNET
greatly reduces the complexity in VRF-Lite deployment.

This MIB module will allow the user to perform the following

  * Create and monitor VRFs
  * Group VRFs to create VRF List
  * Associate/Dis-associate interface to/from a VRF
  * Enable vNET trunking on an interface
  * Specify VRF list per trunk
