Device Template Overview

 

A device template contains configuration and provision settings for a physical device, such as a CPE device or a router, which you manage through Contrail Service Orchestration (CSO). The CSO installation includes several default device templates for CPE devices and other physical devices. You can either use a default CPE device template as is if the template suits your specific topology requirements or customize the default CPE device template to meet your specific requirements. You can also create your own device templates and upload that to CSO. The CPE device templates are specific to the type of device and topology of the solution. The device templates for non-CPE devices are fixed and you cannot customize them. You must assign a device template to each CPE device at the site. You assign a device template to a device in CSO when you add a point of presence (POP). In some cases, you might want all CPE devices to use the same values, through device templates, you have the options to provide the values.

The CPE device templates contain three types of information:

  • Template settings information—It prepares the device for remote activation, connects the device to the peer router, and establishes an IPsec tunnel with the router.

  • Stage-2 configuration template information—It specifies the additional settings that you or your customer can configure for the device. For example, you can enable configuration of LAN and firewall policies. You create these configuration templates in Configuration Designer and provide implementation details in the device template.

  • Stage-2 initial configuration information—It provides the actual values for the stage-2 configuration templates. In general, your customers perform this configuration through the Customer Portal.

The CPE device templates support four deployment models: Hybrid WAN CPE, SD-WAN CPE, Secure Internet CPE, and Managed Internet CPE.

Hybrid WAN CPE

You can use the NFX Hybrid WAN CPE or SRX Hybrid WAN CPE device template for a CPE device in hybrid WAN deployment.
