VRFs Configuration with Terraform

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

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

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

The ndfc_vrfs resource is used to define VRFs in the NDFC fabric. This resource allows you to specify various parameters for the VRF, such as its name, ID, VLAN, and other attributes.

This resource depends on the ndfc_interface_ethernet, ndfc_interface_loopback, and ndfc_interface_portchannel resources which were defined in the previous steps. This ensures that the interfaces are created before the VRFs 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.
