Red Hat Ansible for Network Automation

Compose a playbook with a play that reinitializes layer 3 on network devices running VyOS. Create a playbook named vyos-reinitialize-l3.yml with the following content:

---
- name: >
   reinit layer 3 on
   non-mgmt ifaces of
   VyOS devices
  hosts: vyos
  vars:
    eth_intfs: []
    non_mgmt_eth_intfs: []
    mgmt_intf: eth0

  tasks:

  - name: send command to show interfaces
    vyos_command:
      commands:
      - show interfaces
    register: r

  - name: get interface rows
    set_fact:
      eth_intf_rows: "{{ r.stdout_lines[0]|select('search', '^eth[0-9]+.*')|list }}"

  - name: append to list
    set_fact:
      eth_intfs: "{{ eth_intfs }} + [ '{{ item.split(' ')[0] }}' ]"
    loop: "{{ eth_intf_rows }}"

  - name: show ethernet interfaces
    debug:
      var: eth_intfs

  - name: get non-management interfaces
    set_fact:
      non_mgmt_eth_intfs: "{{ non_mgmt_eth_intfs }} + [ '{{ item }}' ]"
    loop: "{{ eth_intfs | reject('match', mgmt_intf) | list }}"

  - name: show non-management ethernet interfaces
    debug:
      var: non_mgmt_eth_intfs

  - name: remove IPv4 addresses
    vyos_l3_interface:
      name: "{{ item }}"
      state: absent
    loop: "{{ non_mgmt_eth_intfs }}"

  - name: remove addresses from loopback
    vyos_l3_interface:
      name: lo
      state: absent

  - name: disable IPv6
    vyos_config:
      lines:
        - set system ipv6 disable
      save: True

  - name: remove interface descriptions
    vyos_interface:
      name: "{{ item }}"
      state: absent
    loop: "{{ non_mgmt_eth_intfs }}"

  - name: disable OSPF
    vyos_config:
      lines:
      - delete protocols ospf area 0
      save: True

  - name: reboot
    vyos_command:
      commands:
      - command: reboot now
    ignore_errors: yes

  - name: wait for restart
    wait_for_connection:
      delay: 20
      timeout: 120

Perform the play in the playbook to enact the desired changes. If you are having difficulties with typing a playbook of this length, you can find the completed playbook in the playbooks directory on materials.example.com.
