Ansible - getting value of LAN interface

[illusion_rox]

Hi all, 

Is it possible to get the ip address of LAN interface dynamically from each router and then setting it up and ospf router id while running ansible script?

Hi there,

Try the following playbook:

---
- name: set router id
  hosts:
    foo
  connection: network_cli
  
  tasks:
    - name: get IP address
      ios_command: 
        commands: "sh ip int br {{ interface }}"
      register: var_ip_addr

    - name: set OSPF router-id
      ios_config:
        lines:
          - "router-id {{ var_ip_addr.stdout[0].split('\n')[1].split()[1] }}"
        parents: "router ospf {{ pid }}"

...

You hosts.ini will need to look like:

[foo:vars]
ansible_network_os=ios


[foo]
bar001 anisble_host=192.168.1.1 interface=vlan10 pid=0
bar001 anisble_host=192.168.1.2 interface=vlan10 pid=0
bar001 anisble_host=192.168.1.3 interface=vlan10 pid=0

I've been able to test the 'get ip address' task and confirm the multiple split commands return the IP address, but I don't have anything to test the 'set ospf router-id' task on...but that should work too :)

cheers,

Seb.

Dear Seb, 

Sorry returning to this post after sometime. Can you extend your support to advise from where we are getting the values for {{ interface }} and {{ pid }}
