Network Configuration with Terraform

In this section you will be creating the Terraform configuration for the Fabric Networks

Step 1 - Create modules/fabric/networks.tf file

touch ~/workspace/ndfclab/terraform/modules/fabric/networks.tf
code-server -r ~/workspace/ndfclab/terraform/modules/fabric/networks.tf

The ndfc_networks resource is used to define networks in the NDFC fabric. This resource allows you to specify various parameters for the network, such as its name, ID, VLAN, and other attributes. You will be creating two networks: NAC_TF_NET1 and NAC_TF_NET2.

This resource depends on the ndfc_vrfs resource which was defined in the previous steps. This ensures that the VRFs are created before the networks are configured.

Step 2 - Close All Open VSCode Tabs for Next Terraform Section

In your VSCode application; on the keyword press Ctrl + K + W. This should close all open tabs to clear your workspace.
