Re: [ansible-project] Why do I have to split up this set_fact into multiple? or am I doing something incorrect?

Hi can someone please explain why the following two seperate 
'set_fact's
work.

    when: ansible_network_os == 'asa'

You can't use {{ }} inside {{ }}
So correct syntax is

  - name : combine network and wildcard
    set_fact:
       net_mask: '{{network}}/{{wildcard}}'
    when: ansible_network_os == 'asa'


  - name : determine netmask from wildcard
    set_fact:
        mynetmask: "{{ net_mask  |ipaddr('netmask') }}"
    when: ansible_network_os == 'asa'


But this 'combined' effort doesn't work

  - name : determine netmask from network and wildcard
    set_fact:
        mynetmask : "{{ '{{network}}/{{wildcard}}'  |ipaddr('netmask') 
}}"
    when: ansible_network_os == 'asa'

  - name : determine netmask from network and wildcard
    set_fact:
        mynetmask : "{{ (network ~ '/' ~ wildcard)  |ipaddr('netmask') 
}}"
    when: ansible_network_os == 'asa'


I'm trying to understand the limitations of set_facts.

There is no limitation, you just need to use the correct jinja2 syntax.
