calling a role and passing it a different host

[Spiro Mitsialis]

I have playbook that is running for a network switch.  From within this playbook, I want to call a role which will run a IOS Ansible module but the host should be a different device (host).  The different device is its upstream neighbor which the first playbook gets doing a URI call to a database.  I dont have the information before the URI call.

Both devices are listed in my hosts inventory file.

I have tried listing the new host in the role/vars/main.yml file but it still sees the first network switch.

    hosts: xxxxxxx

I have also tried specifying hosts when calling the role:

  - name: call manage trunk vlans

    include_role: 

      name: manage_trunk_vlans

    vars:

      hosts: burnside-lab-srp.gw.mcgill.ca
