Configuring SD-WAN interfaces

In order for us to steer traffic based on SD-WAN rules, first we need to configure SD-WAN interface members. To know more about creating SD-WAN interfaces, refer to the Configuring the SD-WAN interface section.

In our example, we created four SD-WAN interface members. SD-WAN interfaces Internet_A(port1) and Internet_B(port5) for the underlay traffic, and Branch-HQ-A and Branch-HQ-B interfaces for the overlay traffic.

Verify the configurations on the Network > SD-WAN screen:

In the screenshot above, we have configured the Internet_A(port1) and Internet_B(port5) SD-WAN interface members with their Cost values being 0 and 10 respectively. A lower Cost value indicates that this member is the primary interface member, and is preferred more than a member with a higher Cost value when using the Lowest Cost (SLA) strategy.

We also need to configure a static route that points to the SD-WAN interface. To know more about static routes, refer to the Adding a static route section.
