Steps to use an Ansible Playbook

In the below example, we will show steps to use an Ansible Playbook using Jinja2 template and sample parameter file. This example show how to configure LDP protocol:

ocnos_ldp.j2

osboxes@osboxes:~/playbooks$ cat templates/ocnos_ldp.j2

{%if ldp is defined%}

router ldp

{% for peer in ldp.peers -%}

targeted-peer ipv4 {{ peer.address }}

exit

{% endfor %}

{% if ldp.advertise_label_prefix is defined %}

advertise-labels for only_lo to any

{%endif%}

{% for interface in ldp.interfaces -%}

interface {{ interface.name }}

enable-ldp {{ interface.protocol }}

label-switching

exit

{% endfor %}

{%endif%}

We will provide the LDP configuration details in the appropriate host_vars file.

sw2.yml

osboxes@osboxes:~/playbooks$ cat host_vars/sw2.yml

ldp:

peers:

- address: 1.1.1.1

- address: 3.3.3.3

advertise_label_prefix: only_lo

ldp_interfaces:

- { ldp_interface: eth1, ldp_protocol: ipv4 }

- { ldp_interface: eth2, ldp_protocol: ipv4 }

Here is the overall directory structure of the Ansible Playbook and associated files.

osboxes@osboxes:~/playbooks$ tree

|___ansible.cfg

The following is the content of ansible.cfg file which points to hosts-net inventory file.

ansible.cfg

osboxes@osboxes:~/playbooks$ cat ansible.cfg

[defaults]

inventory = hosts-net

host_key_checking = False

retry_files_enabled = False

interpreter_python = auto

osboxes@osboxes:~/playbooks

Following is the content of the hosts-net inventory file. Currently this has details of only one device.

hosts-net

osboxes@osboxes:~/playbooks$ cat hosts-net

[ocnos]

sw2 ansible_host=10.12.9.105

osboxes@osboxes:~/playbooks$

Following is the content of ocnos.yml in group_vars folder.

ocnos.yml

osboxes@osboxes:~/playbooks$ cat group_vars/ocnos.yml

ansible_connection: network_cli

ansible_network_os: ocnos

ansible_become: yes

ansible_become_method: enable

ansible_ssh_user: ocnos

ansible_ssh_pass: ocnos

osboxes@osboxes:

The below playbook pushes the ldp configuration created using the template file 'ocnos_ldp.j2' for all the ocnos hosts using the appropriate host_vars file 'sw2.yml':

ldp-playbook.yml

(ansible) osboxes@osboxes:~/playbooks$ cat ldp-playbook.yml

---

- hosts: ocnos

gather_facts: no

tasks:

- name: configure LDP config on OcNOS

cli_config:

config: "{{ lookup('template', 'templates/{{ ansible_network_os }}_ldp.j2') }}"

Configuration on the OcNOS device before executing the Ansible Playbook:

#show running-config ldp

Now we can execute the Ansible playbook and below are the logs that will be seen.

(ansible) osboxes@osboxes:~/playbooks$ ansible-playbook ldp-playbook.yml

PLAY [ocnos] ******************************************************************************************************

TASK [configure LDP config on OcNOS] ******************************************************************************

changed: [sw2]

PLAY RECAP ********************************************************************************************************

sw2 : ok=1 changed=1 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0

Now check the configs on the OcNOS device. which should show the LDP configurations.

#show running-config ldp

router ldp

targeted-peer ipv4 1.1.1.1

exit-targeted-peer-mode

targeted-peer ipv4 3.3.3.3

exit-targeted-peer-mode

advertise-labels for only_lo to any

interface eth2

enable-ldp ipv4

interface eth1

enable-ldp ipv4

The below playbook shows how to check the runtime status of LDP protocol through the 'show ldp session' command and prints its output. It is assumed that the neighboring nodes are configured accordingly to get the LDP session up and running.

showldp-playbook.yml

osboxes@osboxes:~/playbooks$ cat showldp-playbook.yml

---

- hosts: ocnos

gather_facts: no

tasks:

- name: show LDP config ocnos

cli_command:

command: show ldp session

- name: debug

debug:

msg: "{{ result.stdout_lines }}"

osboxes@osboxes:~/playbooks$

When you run this playbook, the following will be its output. Parsing of the show command output needs to be done to determine if the runtime status of the protocol is fine.

(ansible) osboxes@osboxes:~/playbooks$ ansible-playbook showldp-playbook.yml

PLAY [ocnos] ******************************************************************************************************

TASK [show LDP config ocnos] **************************************************************************************

ok: [sw2]

TASK [debug] ******************************************************************************************************

ok: [sw2] => {

"msg": [

"Peer IP Address IF Name My Role State KeepAlive UpTime",

"3.3.3.3 eth2 Passive OPERATIONAL 30 03:58:20",

"1.1.1.1 eth1 Active OPERATIONAL 30 03:58:20"

]

}

PLAY RECAP ********************************************************************************************************

sw2 : ok=2 changed=0 unreachable=0 failed=0 skipped=0 rescued=0 ignored=0

(ansible) osboxes@osboxes:~/playbooks$

The below playbook is to unconfigure the LDP configuration on the OcNOS device.

osboxes@osboxes:~/playbooks$ cat unconfigureldp-playbook.yml

---

- hosts: ocnos

gather_facts: no

tasks:

- name: give "no router ldp" command

Jinja2 Templates for configuring OcNOS

In this section, we will provide a few Jinja2 templates which can be used to configure a few protocols in OcNOS. Also a sample yaml parameter file is provided for each j2 template with explanations of the parameters. While creating the Jinja2 template, only the commonly used configuration is considered. Customers can use these templates as such, if it meets their configuration needs or can modify them accordingly.

Limitations

The following are the current limitations while configuring OcNOS through Ansible.

1. The following commands in OcNOS require the device to be rebooted to be effective.

• hardware-profile

• forwarding profile

• maximum-paths

• copy empty-config startup-config

Ansible returns success while configuring these commands. However, the device needs to be rebooted to make these effective.

2. By default, ANSIBLE_PERSISTENT_COMMAND_TIMEOUT is set to 30 (seconds). While pushing large configs through Ansible which might be taking more time than this default timeout, it is suggested that to increase the ansible_command_timeout to appropriate value. In group_vars/ocnos.yml, it is suggested to add the below line with appropriate timeout value:

ansible_command_timeout: 1800

3. While configuring the below commands, there are certain warning messages shown to the customer. Currently Ansible treats them as failure and returns failure even though it is successful. It is suggested that the user takes appropriate action while configuring these commands.

• no ip vrf <vrf-id>

• While re-configuring shaping as part of QoS:

policy-map type queuing shaper

class type queuing defaultq

shape 10 gbps

exit
