Azure Peering Service customer walkthrough

This section explains the steps to optimize your prefixes with an Internet Service Provider (ISP) or Internet Exchange Provider (IXP) who is a Peering Service partner.

See Peering Service partners for a complete list of Peering Service providers.

Activate the prefix

If you have received a Peering Service prefix key from your Peering Service provider, then you can activate your prefixes for optimized routing with Peering Service. Prefix activation, alignment to the right OC partner, and appropriate interconnect location are requirements for optimized routing (to ensure cold potato routing).

To activate the prefix, follow these steps:

  1. In the search box at the top of the portal, enter peering service. Select Peering Services in the search results.

  3. In the Basics tab, enter or select your subscription, resource group, and Peering Service connection name.

  4. In the Configuration tab, provide details on the location, provider and primary and backup interconnect locations. If the backup location is set to None, the traffic fails over to the internet.


    • The prefix key should be the same as the one obtained from your Peering Service provider.
