Underlay Network Plan
WAN Link Template Plan
WAN links are the basis for building an EVPN interconnection network. To prevent repeated configuration of parameters for each site, configuration information such as the number of gateways and WAN-side links is abstracted into a WAN link template. The site WAN model is configured through the WAN link template. Therefore, after creating sites, you need to plan a WAN link template for each site. If multiple sites have the same WAN-side configurations, including the gateway type, WAN link, and interconnection link between two gateways, the same WAN link template can be used.

WAN Link Parameter Plan
You must configure physical link parameters on the WAN side before deploying sites through ZTP.

The upstream and downstream bandwidths must be set based on the actual bandwidth resources provided by the carrier.
NTP Plan
When an AR router reports performance data, it carries timestamps in packets. If the time on the AR router is set incorrectly, the time in performance data viewed by administrators is inconsistent with the actual time. Therefore, NTP is configured on iMaster NCE-Campus to synchronize the time on devices at the site.

Underlay WAN Route Plan
After a site egress device connects to a WAN, the device must have reachable underlay network (physical network) routes to the PE, so that an overlay network can be normally established to forward services. Static, BGP, and OSPF routes can be configured for the WAN side of the underlay network. In this example, all sites use static routes.
WAN interfaces of the underlay network use the default configuration.
