Objective

• Continue network automation creation
• Store automation in code repository

Step 1 - VLAN Interfaces

Furthering the VLAN configuration, we’ll set up some l3 interfaces aligned to the vlans created in another playbook. Create a new playbook named vlan-interfaces.yaml and add the following contents:

---
- name: Setup VLAN interfaces
  hosts:
    - all
  tasks:
    - name: Configure VLAN Interfaces
      cisco.ios.ios_l3_interfaces:
        config:
          - name: "Vlan{{ vlan }}"
            autostate: false
            ipv4:
              - address: "192.168.{{ vlan }}.1/24"
            ipv6:
              - enable: false
      loop: "{{ range(200, 221)|list }}"
      loop_control:
        loop_var: vlan

Step 2 - Static Routes

Let’s create another playbook that configures some static routes on our network appliance. Create a new file in the playbooks directory named static-routes.yaml and add the following contents:

---
- name: Setup static routes
  hosts:
    - all
  tasks:
    - name: Configure static routes
      cisco.ios.ios_static_routes:
        config:
          - address_families:
              - afi: ipv4
                routes:
                  - dest: 10.1.1.0/24
                    next_hops:
                      - forward_router_address: 192.168.1.1
                        name: route
                  - dest: 10.1.2.0/24
                    next_hops:
                      - forward_router_address: 192.168.2.1
                        name: route2
                  - dest: 10.1.3.0/24
                    next_hops:                       
                      - forward_router_address: 192.168.3.1
                        name: route3

Step 3 - Configure OSPF

Finally, we’ll create one last playbook to setup OSPF on our network appliance. Create a new file in the playbooks directory named ospf.yaml and add the following contents:

---
- name: Setup OSPF
  hosts:
    - all
  tasks:
    - name: Configure OSPFv2
      cisco.ios.ios_ospfv2:
        config:
          processes:
            - process_id: 1
              max_metric:
                router_lsa: true
                on_startup:
                  time: 110
              areas:
                - area_id: "0"
                  capability: true

Step 4 - Save and Commit Code

Same as before, ensure your code has been saved in your code repository. If you’re using an IDE, ensure you’ve committed/pushed your code.
