Interface Configuration with Terraform

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

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

touch ~/workspace/ndlab/terraform/modules/fabric/interfaces.tf
code-server -r ~/workspace/ndlab/terraform/modules/fabric/interfaces.tf

After you define the switches in the inventory you can start defining the interfaces for the switches. In this example you will define three loopback interfaces, one Ethernet interface and one Port Channel interface.

resource "ndfc_interface_loopback" "nac_interface_loopback_1" {
  policy        = "int_loopback"
  deploy        = false
  serial_number = var.site1-leaf1-serial
  interfaces = {
    "Loopback100" = {
      interface_name        = "loopback100"
      admin_state           = false
      interface_description = "Configured using Terraform"
      vrf                   = "default"
      ipv4_address          = "192.168.20.1"
      ipv6_address          = "2002:db8::1"
      route_map_tag         = "100"
    }
    "Loopback101" = {
      interface_name        = "loopback101"
      admin_state           = false
      interface_description = "Configured using Terraform"
      vrf                   = "default"
      ipv4_address          = "192.168.21.1"
      ipv6_address          = "2002:db8::1"
      route_map_tag         = "100"
    }
    "Loopback102" = {
      interface_name        = "loopback102"
      admin_state           = false
      interface_description = "Configured using Terraform"
      vrf                   = "default"
      ipv4_address          = "192.168.22.1"
      ipv6_address          = "2002:db8::1"
      route_map_tag         = "100"
    }
  }
