VRF Form

The VRF form provides details about the selected VRF, and VRF Lite participating to form an L3 VPN.

Use the VRF form for the following tasks:

  • Monitor the VRFs, MVRFs, or VRF Lites participating in the selected L3 VPN or MVPN. The MVRF and MVRF Status tabs appear in the VRF form only when multicast services are enabled in the selected VRF.
  • Check the PE Interfaces and CE interfaces tab to view the status and other attributes of the selected VRF.
  • Check the Incidents tab to view the cause of the change in the status.
  • Access an L3 VPN topology map view of the network.

Basic Attributes

Attribute Description
Name The name of a VRF or VRF Lite as configured on the PE router.
PE Node

The name of the router. The name can be hostname or IP address. The PE node is the Provider Edge router on the edge of the service provider's network that communicates with other provider devices and with customer devices. The selected VRF or MVRF is configured on the PE Node. PE node on VRF lite shows the VRF Lite router though it is named PE router. Click (the Lookup icon) to access the node details. For more information for the node, see NNMi Help.


Overall status for the current VRF. Possible values are:

No Status- The VRF is Not Managed.

Normal - The operstatus of the VRF is Up, status is Normal.

Unknown - The VRF is not reachable or not responding.

Critical - The operstatus of the VRF is Down when the status of all the interfaces on the VRF is Down.

Management Mode

The NNM iSPI for MPLS supports management of VRFs. Possible values are:

  • Managed – The selected VRF is managed.
  • Not Managed – The selected VRF is not managed.

To modify the Management Mode, select "Managed" or "Not Managed" respectively from the Management Mode list of the VRFform.

  • Out of Service – A node is unavailable because it is out of service. NNMi does not update discovery information or monitor these nodes. This attribute is useful for notifying NNMi when a device is temporarily out of service.

Out of Service is an NNMi supported mode. The NNM iSPI for MPLS does not allow users to store 'Out of Service' value from the Management Mode list.

For more information, see the Help for NNMi; View the Management Mode for an Object in Your Network.

Management Type

Inheritance type for the selected VRF. An MPLS object inherits management mode of its container object. Management Type displays the type of container object from which the selected VRF has inherited the Management Mode. Possible values are:

  • Node Inherited - The selected VRF inherits management mode from a node.
  • VPN Inherited - The selected VRF inherits management mode from a node.
  • Self - The selected VRF is Not Managed but it belongs to a Managed node, participating in a Managed VPN.
You cannot change Management Type of an Not Managed VRF to Self if it is VPN Inherited.
  • Regional Inherited- One of the VRF belonging to a VPN at Regional level is Not Managed. In addition, these VRFs are not affected by management changes made at the Global level. 
'Regional Inherited' type is only applicable for a Global Manager. This is because a VRF Not Managed in a regional manager has a direct effect on the Global Manager. However, any VPN managed/not managed at Global level will not affect a VRF that is 'Regional Inherited' .


Description The description value is obtained from the PE router during the discovery process.
RD The numerical route distinguisher of the VRF. This value is stored on the PE router and is unique across the service provider's network. The unique value provides the accurate resolution of the overlapping IP address domains.
Multicast VRF

The selected VRF has permissions to transmit multicast data packets. The status of the flag is either true or false. This flag is only available for Cisco nodes. True is represented by .  

VRF Lite Enabled The selected VRF supports VRF Lite and Shadow routing. True is represented by .
IPv6 Enabled The selected VRF supports IPv6. True is represented by
Hub VRF The selected VRF is a Hub VRF. True is represented by
QA Probes The selected VRF is configured to run tests from the iSPI Performance for Quality Assurance (QA). True is represented by
Configured Interfaces The total number of interfaces configured on the selected VRF.
Discovered Interfaces The number of interfaces on the selected VRF that are discovered by the NNM iSPI for MPLS. The rows on the PE Interfaces tab are same as the number of the discovered interfaces.
Create Time

The time when the VRFs was discovered.

Status Last Modified The selected VRF is polled in the regular intervals and status change is recorded. Status Last Modified shows the date and time on which the status of the selected VRF was last set.
Mean Time Between Failure

Total time for which the selected VRF was last available divided by the total number of occurrences when the status of the VRF was down.

For example, if the status of the selected VRF is Up at 10:00 AM and the status changes to Down at 10:20 AM. Again, the status of the VRF changes from Down to Up at 10:30 AM and is again Down at 10:40 AM. The status is changed from Down to UP at 10:50 AM. Therefore, the Time Between Failures is the total time when the selected VRF was available ( 50 minutes) by the total number of occurrences when the status was down (2) (MTBF = .50 minutes/ 2).

When the iSPI Performance for Metrics is not installed, value is Not Computed.

Mean Time To Recovery The time taken to restore the status of the selected VRF from Down to Up divided by the total number of occurrences when the status of the VRF was changed from Down to Up. When the iSPI Performance for Metrics is not installed, value is Not Computed.
L3 VPN The selected VRF belongs to the specified L3 VPN. Access the L3 VPN form from (the Lookup icon).
VRF Peer

The VRF- VRF Lite relationship. When a PE VRF and a VRF Lite participating in the same VPN are discovered, they are termed as peers. For a VRF Lite object, when the VRF form is opened its corresponding PE VRF is shown as its peer. Similarly, when PE VRF is opened, the corresponding VRF Lite is shown as its peer. You can open a VRF peer by clicking on the VRF peer object. The VRF peer field remains blank if no VRF- VRF Lite relationship exists. You can open a VRF Peer by using (the Lookup icon).

Look up shows a "Cannot perform operation" pop-up if you do not have access to the VRF peer.
