Create a Virtual NNI Link Between Multi-Area Boundary NodesNEW!

About this task

Perform this procedure to create a virtual NNI link between Multi-area boundary nodes.

The assumption is that you are creating the CLIP and the logical interface for the first time. You can also use the table-based tab to apply the configuration to an existing interface.

Procedure

  1. In the navigation pane, expand Configuration > IP.
  2. Select IP.
  3. Select the Circuitless IP tab.
  4. Select Insert.
  5. In the Interface field, add a CLIP interface number.
  6. Type the IP address.
  7. Type the network mask.
  8. Select the type of loopback interface for the virtual NNI link:

    • circuitlessIPMAVirtualLinkHome

    • circuitlessIPMAVirtualLinkRemote

    Note

    Note

    If you configure the loopback interface for the virtual NNI link in the home area, you must configure IS-IS on the logical interface in the remote area, and vice versa.

  9. Optional: For Name, type a name for this interface.
  10. Select Insert.
  11. In the navigation pane, expand Configuration > Fabric.
  12. Select IS-IS.
  13. Select Logical Interfaces tab.
  14. Select Insert.
  15. For Id, type the index number that uniquely identifies this logical interface.
  16. Optional: For Name, type the name of this logical interface.
  17. For Type, select ip.
  18. For DestIPAddr, type the destination IP address for the logical interface.
  19. Select Multi-area Virtual Link to configure a Multi-area virtual link on this interface.
    Note

    Note

    If you configure the loopback interface for the virtual NNI link in the home area, you must configure IS-IS on the logical interface in the remote area, and vice versa.

  20. Select Insert.

What to do next

Configure IS-IS and SPBM on the logical interface.
