Modifying a region

  1. Click to open the main menu.
  2. In the main menu, select Deployment Regions. The deployment regions page opens, showing a graphical representation of regions already created.
  3. Right-click the region and select Edit Details... from the contextual menu.
  4. Modify any of the following settings for the region:
    • General/Description
    • General/Location
    • System IP Pool/IP Blocks
    • Inter Switch Link IP Pool/IP Blocks
    • Out of Band Management Pool/IP Blocks
    • EVPN Profile/Control Plane
    • Route Target/Global Index
    • Protocol Authentication/BGP
    • EVI
    • VNI
  5. Click SAVE. The system saves the new region details.

Implications of modifying a region

A region is a container for intents, and every fabric intent you create within a region inherits the region's properties (such as configurations for EVPN peering or eBGP authentication).

If you modify the region's settings, the system does not automatically propagate the changes to pre-existing fabric intents within the region.

To update existing fabric intents with the new region settings, you must regenerate each of the fabric intents.

  • If you have saved, but not generated, a fabric intent, no action is required; the region settings are not inserted into the fabric's code until you generate the topology, so the latest settings are picked up immediately when you do generate the fabric topology.
  • If you have generated but not deployed a fabric intent, you need to update and re-save the fabric intent, then regenerate the topology. The newly generated fabric intent includes the latest settings from the updated region.
  • If you have deployed a fabric intent you need to create a new version of the intent, regenerate the topology, and deploy the result. Regenerating the new version of the fabric intent inserts the latest region settings into the fabric code, and deploying the fabric intent updates the working node configurations accordingly.

When you regenerate the fabric intent, the system updates the settings to match the current configuration of the region.

You can then add the new version of the fabric intent to the region's deployment pipeline, and deploy the fabric intent from the pipeline normally.
