L3 VPN Form

The L3 VPN form provides details of the VRFs participating to form an L3 VPN. All PE routers containing VRFs relevant to the named L3 VPN are grouped in one VPN and displayed in the inventory. This topic includes the following sections:

Use the L3 VPN Form to perform the following tasks:

  • Monitor the VRFs participating in the selected L3 VPN.
  • Check the VRFs tab to view the status of the VRFs participating in the selected L3 VPN.
  • Navigate to the VRF form to check more details of the selected VRF.
  • Check the MVPN tab to view the status of the available MVRFs participating in the selected MVPN. The MVPN tab appears only when the multicast services are enabled in the selected L3 VPN.
  • Check the Incidents tab to view the cause of the change in the status.
  • Access the L3 VPN topology map view of the network.

Monitor LSPs

In addition to monitoring VRFs, NNM iSPI for MPLS monitors LSPs. To enable monitoring LSPs:

  1. Open VRFs in a new window

    1. From the MPLS workspace, click L3 VPN Inventory.
    2. Select a VPN to open the L3 VPN form.
    3. In the VRFs tab, click to open the VRFs in a new window.
  2. Select two VRFs for which you want to monitor the LSP.
  3. Click Actions.
  4. Click Monitor LSP.

The "LSP set for monitoring." message is shown in a new window.

The monitored LSP can be viewed in the Monitored LSP Inventory.

You may encounter the following messages:

  • "No LSP Path defined for monitoring" - displayed if no LSP path exists between the selected VRFs.
  • "LSP path not available, because there is no neighboring relation between two VRFs" - displayed if there is no neighboring relation between the select VRFs.

Overall Status
Attribute Description
Status

The overall status of the L3 VPN. The status of the L3 VPN is derived and calculated based on the status of all the VRFs participating in the L3 VPN. Possible values are:

 No Status - The status of an L3 VPN is 'No Status' when:

  • An L3 VPN is newly formed and not polled.
  • If all the VRFs participating to form an L3 VPN are in 'Not Managed' mode.
  • When VRFs participating in the L3 VPN are not mapped to any interfaces and hence, not polled.

Normal - The status of all the VRFs participating in the L3 VPN is Normal.

Unknown - The status of all the VRFs participating in the L3 VPN is Unknown.

Warning - The status of one or more the VRFs participating in the L3 VPN is Unknown, however none of them is Critical.

Minor- The status of the L3 VPN is Minor if the status of one or more, but not all, of the VRFs participating in the L3 VPN is Critical.

Critical - The status of the L3 VPN is Critical if the status of all the VRFs participating in the L3 VPN is Critical. It is also critical when the HUB VRF is critical.
Status Last Modified Status Last Modified shows the date and time on which the status of the selected L3 VPN was last set.

Incidents Tab

The VPN Form provides details about the selected VPN.

The Incidents tab provides details of all the Service Impact incidents associated with the selected L3 VPN. The service impact incident is useful to identify and troubleshoot the service that is affected.

NNMi generates incidents for a CE node or interfaces that are participating to form an L3 VPN. The NNM iSPI for MPLS receives the notification and generates an incident that provides details of the affected L3 VPNs on the network. The NNM iSPI for MPLS generates multiple service impact incidents such as Interface Down or Node Down for an L3 VPN. The status of the L3 VPNs does not change with the service impact incidents.
