If you're managing multiple Autonomous Systems (AS) and want to simplify your routing policies, using AS-SET objects is an efficient solution. AS-SET objects allow you to group AS numbers, making it easier to manage routing configurations for import and export rules, especially when dealing with complex network setups.

What are AS-SET Objects?

An AS-SET is a collection of AS numbers grouped together to represent a set of networks in a simplified manner. By using AS-SET objects, network administrators can efficiently manage and automate routing policies, especially when multiple AS numbers are involved. This can help streamline operations for networks like ISPs, data centers, and other enterprises with multiple AS allocations.

Why Use AS-SET Objects?

  • Simplifies Routing Configurations: Instead of configuring import and export rules for each AS individually, an AS-SET allows you to apply these rules to a group of AS numbers simultaneously, reducing configuration complexity.
  • Enhanced Network Automation: Using AS-SETs improves automation for routing policies, ensuring quicker and more consistent network updates.
  • Scalability: As your network grows, you can easily add or remove AS numbers from the AS-SET without having to reconfigure individual routes.

How to Create and Manage AS-SET Objects

To create and manage AS-SET objects, you will need access to a Regional Internet Registry (RIR) like APNIC.

Here’s a simplified overview:

  1. Access Your RIR Portal:
    • Log into your APNIC or relevant RIR account where your AS numbers are registered.
  2. Create an AS-SET Object:
    • Navigate to the section where you can manage routing objects.
    • Select the option to create a new AS-SET and assign it a unique name (e.g., AS-CAPTI).
    • Add your AS numbers to the AS-SET.
  3. Update Your Routing Policies:
    • Configure your import and export policies using the newly created AS-SET object. This allows your network to automatically recognize and apply the routing policies to all AS numbers within the set.
  4. Monitor and Manage the AS-SET:
    • Regularly update the AS-SET as your network grows or changes.
    • Remove or add AS numbers as needed, ensuring that your routing policies stay consistent.

For a more detailed guide on creating and managing AS-SET objects, you can refer to APNIC’s official guide here.

By using AS-SET objects, you can significantly simplify and automate your network management, making it easier to scale and adapt your routing policies as your network expands.
