A brief about Cisco Viptela SDWAN Templates

A brief about Cisco Viptela SDWAN Templates 

Today I am going to talk about the use of the template in the Cisco Viptela SDWAN vManage as it is one of the important way to push the configuration to the devices. As you guys know that in vManage, all the features are configured through templates.

Before the configuration pushed via vManage in the form of template vEdge devices should be registered with vManage and once registered all configurations will be configured to vEdge/cEdge via vManage and we wouldn’t be able to configure anything through the CLI. But you still have option to use CLI in case you dont want to assign template to the vEdge.

There are two types of Templates, Device & Feature Templates. First define the device template, then the feature template. 

Feature Template in vManage

For each "feature" you want to set, we produce a feature template. The system setup, VPN, VPN interface, OSPF, EIGRP, BGP, AAA, etc are a part of feature template

1.Log into the vManage console >>> Click Configuration > Templates >>> Confirm that the Feature Templates tab is selected, then click Add Template

Now in the feature template, Configure Tunnel Parameters for which you need to Choose a template name and description for the Tunnel interface. Under Basic Configuration, choose the Global option and set the shutdown option to NO.

In this way we have multiple feature templates you can create on the basis of the requirement, if you dont see the feature template, you have option " CLI add-on feature template" where you can add the cli commands to push via vmanage to devices.

Additionally, commands that are qualified for the device but not available in Cisco vManage can be specified using a CLI add-on feature template.

Device Template in vManage
The whole operating configuration of a device is defined by its device templates. Numerous feature templates make up a device template. Each feature template specifies how a certain Cisco SD-WAN software feature should be configured. 

An asterisk (*) signifies that certain feature templates are required and others are optional. There is a factory-default template for each necessary feature template and several optional feature templates. You can utilize the factory-default template or make a custom feature template for software features that have one.

Step 1: From the Cisco vManage menu, choose Configuration > Templates.
Step 2: Click Device Templates.
Step 3: Click the Create Template drop-down list, and select From Feature Template.
Step 4: From the Device Model drop-down list, select the type of device for which you wish to create the template.
Step 5: In the Template Name field, enter a name for the device template.

We will talk these templates in details one by one in order to understand the concept in more depth and the way they are implementing in the SDWAN environment.
