SD-Branch Configuration: Manage Template Automation, Not Cli Boxes

When networks become steeped in complexity, as they are with legacy WANs, the last thing companies need is more manual processes. Tedious and monotonous configurations, and the lifecycle management of many single-function devices, are time-consuming and costly.

This burden not only adds potential risk due to human error, but complicates network operations, managing bandwidth, local breakouts, QoS policies and deployment timeframes. These factors, among others, are driving the need for network virtualization, automation and software that manages network infrastructure based on business policies to accommodate digital transformation initiatives.

An effective way to simplify tedious network configuration tasks and avoid unnecessary manual processes is with template-based SD-WAN configuration vs. traditional CLI hardware administration.

The benefit of an SD-WAN configuration template is having the same relationships applied to multiple branch offices or groups of branches. Pre-defined configuration templates automate many time-consuming and repetitive tasks, and mask complexity by eliminating the need to know every detail about how to achieve a specific task. By simply selecting target elements, the template automatically applies the appropriate configurations.

There are several important reasons to adopt the templated SD-WAN approach but chief among them are: the need for local Internet breakouts to accelerate SaaS application access, offload non-business critical applications and increase site-WAN bandwidth; and integrated NGFW security services (in some cases two layers of policies) for the purposes of uniformly protecting site-to-Internet access and site-to-site traffic, and defining security zones.

Versa Secure Cloud IP Services Platform

The Versa Secure Cloud IP Platform includes four categories of templates that are merged into a single configuration system. The final configuration is centrally pushed by Versa Director to Versa FlexVNF nodes located within branch offices, co-location facilities or the cloud.

There is no need to build monolithic configurations. Versa SD-WAN templates act as configuration building blocks using small, manageable, modular templates with distinct permissions for different users, which also provides administrators with a mix and match approach to add elements as needed.

Versa features four categories of templates:

1. Common Template

    • Used across multiple devices of the tenant
    • Custom applications
    •  Gets pushed to all devices
    •  Configuration elements include zones, address groups, DHCP option profiles, interfaces, routing instances, SNMP, NTP. Each element can be defined and used across multiple devices.

2. Device Template

    • Built through workflow
    • Number of WAN/LAN interfaces
    • Number of transport domains
