In order for us to steer traffic based on SD-WAN rules, first we need to configure SD-WAN interface members and assign them to SD-WAN zones. For more information about SD-WAN zones, see SD-WAN zones.
In our example, we created two SD-WAN zones. The
virtual-wan-link SD-WAN zone for the underlay traffic passing through the
Internet_B(port5) interfaces, and the
Overlay SD-WAN zone for the overlay traffic passing through the
Go to Network > SD-WAN and select the SD-WAN Zones tab to verify the configurations.
In this screenshot, we have configured the
Internet_B(port5) SD-WAN interface members with their Cost values being
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. For more information static routes, see Adding a static route.
