CISCO-VRF-MIB
AI MIB Summary
The CISCO-VRF-MIB enables the monitoring and configuration of Cisco IOS/IOS-XE routing instances, specifically managing Virtual Routing and Forwarding (VRF), VRF-Lite, and vNET parameters including interface associations, VRF groupings, and trunking states. It provides granular visibility into the creation, deletion, and operational status of independent routing tables to support traffic separation for MPLS VPNs and IP-based hop-by-hop virtualization without requiring MPLS labels.
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

ciscoVrfMIBThe 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.

ciscoVrfMIBNotifs OBJECT IDENTIFIER .1.3.6.1.4.1.9.9.711.0 |
cvVrfIfUpThis notification is generated when:
a. The ifOperStatus of an interface associated with a VRF
changes to the up(1) state.
b. When an interface with ifOperStatus = up(1) is
associated with a VRF.
The interface is identified by ifName and the VRF is
identified by cvVrfName varbinds respectively. NOTIFICATION-TYPE .1.3.6.1.4.1.9.9.711.0.1 |
cvVrfIfDownThis notification is generated when:
a. The ifOperStatus of an interface associated with a VRF
changes to the down(2) state.
b. When an interface with ifOperStatus = up(1) state is
disassociated with a VRF.
The interface is identified by ifName and the VRF is
identified by cvVrfName varbinds respectively.
If all the interfaces associated with the VRF are in down(2)
state or if there are no more interfaces associated with the
VRF, then the cvVrfOperStatus will have a value of down(2). NOTIFICATION-TYPE .1.3.6.1.4.1.9.9.711.0.2 |
cvVnetTrunkUpThis notification is generated when the ifOperStatus of a vNET
trunk interface changes to the up(1) state. The interface is

here can be associated to a vNET trunk interface, which would
then act as a trunk carrying traffic for all VRFs in the VRF

associated with a VRF instance. SEQUENCE OF CvVrfInterfaceEntry .1.3.6.1.4.1.9.9.711.1.2.1 |
cvVrfInterfaceEntryAn entry in this table represents an interface to which a VRF
is associated. A VRF can be associated to multiple interfaces.
There will be one entry per interface for each VRF instance in
this table. CvVrfInterfaceEntry .1.3.6.1.4.1.9.9.711.1.2.1.1 |
cvVrfInterfaceIndexThis is a unique index for an entry in this table. A non-zero
index for an entry indicates the ifIndex for the corresponding
interface entry in the ifTable. Note that this table does not
necessarily correspond one-to-one with all entries in the
Interface MIB. InterfaceIndex .1.3.6.1.4.1.9.9.711.1.2.1.1.1 |
cvVrfInterfaceTypeThe VRF type of this interface. The type of the interface is
determined based on the VRF associated with this interface.
If the VRF is not tagged with vnet tag then the type will be
vrfEdge. If the VRF is tagged with vnet tag then it will become
vnetEdge. For vNETTrunkSI, the sub-interface in question is
automatically created for a VRF when trunking is enabled on the
main interface.ro CvVrfIfType .1.3.6.1.4.1.9.9.711.1.2.1.1.2 |
cvVrfInterfaceVnetTagOverrideThis object can be used to over-ride the vNET tag assigned
to the VRF traffic going through this interface. This object is
applicable only if the cvVrfInterfaceType of this interface
has a value of vNETTrunkSI(1).
By default the tagged traffic will use the value denoted by
cvVrfVnetTag of this VRF. In which case this object will
have a value of zero(0).
A set with a value of zero(0) will revert the tag assignment
behaviour to default behaviour mentioned above.rw CvVnetTagOrZero (0 | 2..4094) .1.3.6.1.4.1.9.9.711.1.2.1.1.3 |

vNET trunking, it will carry the traffic for the VRFs which are
tagged with the vNET tag. CvInterfaceEntry .1.3.6.1.4.1.9.9.711.1.2.2.1 |
cvInterfaceVnetTrunkEnabledThis object represents the vNET trunking status for this
interface. When enabled for vNET trunking the interface will
