Unable to pass Role/X/Var variables to Task

[Yogi Raghunathan]

Hello Folks,

Trying to do a basic example for roles for generating configs. I cannot get to pass the variable to the tasks. Any help is appreciated. 

$ ansible --version

ansible 2.4.2.0

  config file = /home/cisco/ansible.cfg

  configured module search path = [u'/home/cisco/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']

  ansible python module location = /usr/lib/python2.7/dist-packages/ansible

  executable location = /usr/bin/ansible

  python version = 2.7.12 (default, Nov 20 2017, 18:23:56) [GCC 5.4.0 20160609]

$ more roles/router/tasks/main.yml

---

  - name: generate configuration files

    template: src=router.j2 dest=/home/cisco/ansible/cfgs/{{item.hostname}}.txt

    with_items: " {{ routers }}"

$ more roles/router/vars/mail.yml

---

 routers:

  - { hostname: router-rtr1 }

  - { hostname: router-rtr2 }

  - { hostname: router-rtr3 }

  - { hostname: router-rtr4 }

  - { hostname: router-rtr5 }

  - { hostname: router-rtr6 }

...

$ ansible-playbook config-gen.yml

PLAY [Generate router configuration files] ****************************************************

The filename must be main.yml, not mail.yml that you have.
