ASN Pools

ASN Pool Overview

You can create resource pools during the design phase or just before you need them during the build phase. When you assign resources to managed devices in your network (blueprint), they are pulled automatically from the pool you specify. In cases where you need to assign a specific network identifier you have the option of assigning a resource individually. To prevent shortages as a network grows, network design best practices recommend defining more resources than are required for the initial design.

Superspines, spines, leafs and Layer 3 servers use BGP to exchange routing information in the underlay. Autonomous system numbers (ASNs) must be assigned to each device, either from the same pool or from different pools. They can also be assigned individually if a specific resource must be assigned to a specific device. ASN pools include the following details:

Pool Name
To identify the resource pool.
Total Usage
Percentage of ASNs in use for all ranges in the resource pool. (Hover over status bar to see number of ASNs in use and total number of ASNs in the pool.) (New in version 3.3.0)
Range Usage
The ASNs included in the range and the percentage that are in use. (Hover over status bar to see number of ASNs in use and total number of ASNs in that range.) (New in version 3.3.0)
Status
Indicates if the pool is in use.
Tags (optional)
To enable filtering by user-specified categories.

From the web interface, navigate to Resources > ASN Pools.

Cloning ASN Pool

Instead of entering all details for a new ASN pool, you can clone an existing one, give it a new name and customize it.

Creating ASN Pool

  1. From the web interface, navigate to Resources > ASN Pools and click Create ASN Pool.
  2. Enter a name, (optional) tags, and a range.
    • To specify an additional range, click Add a range and enter the range.
  3. Click Create to create the pool and return to the list view.

When the blueprint is ready, you can assign resources by updating assignments in the Staged > Physical view.

Editing ASN Pool

If any ASNs in an ASN pool are in use, they cannot be removed from the pool.

  1. Either from the list view (Resources > ASN Pools) or the details view, click the Edit button for the pool to edit.
  2. Make your changes.
    • To add a range, click Add a range.
    • To change a range, change the existing range numbers.
    • To remove a range, click the X to the right of the range to delete.
  3. Click Update to update the pool and return to the list view.

Deleting ASN Pool

If any ASNs in an ASN pool are in use, the pool cannot be deleted.

  1. Either from the list view (Resources > ASN Pools) or the details view, click the Delete button for the pool to delete.
  2. Click Delete to delete the pool and return to the list view.
