SD-WAN templates
While the generic Jinja CLI templates mostly handle the Underlay, Overlay, and Routing pillars, the SD-WAN pillar uses the GUI-based SD-WAN templates. Furthermore, we will create a separate template for each profile and for each number of Hubs in the region.
When a site has an extra WAN link, the extra WAN link must be configured. Similarly, when a region has two Hubs, rather than one Hub, the second Hub must be configured too. |
We are going to configure all the WAN-facing interfaces—both underlay and overlay—to be part of our SD-WAN bundle. This way, all the traffic steering will be controlled by the SD-WAN rules. And since our "foundation" is generic, we do not need to reconfigure the other pillars (for example, IPsec and BGP), when changing SD-WAN rules.
