The PAN-OS® SD-WAN plugin previously supported a limited number of private link types, which complicated configurations for organizations using more than three distinct private link providers. This limitation required administrators to implement configuration workarounds, preventing the SD-WAN plugin from correctly establishing one-to-one device peering based on the link type.

To address this, four additional link types are now available: Private 1, Private 2, Private 3, and Private 4. These function identically to the existing MPLS link type and inherit its aggressive path monitoring characteristics. By allowing each distinct private link to be assigned a unique type, this feature enables the SD-WAN plugin to correctly determine one-to-one device peering for the overlay network, eliminating the need for configuration workarounds.
