I have created a couple of arrays using responses from commands via
ntc_ansible to a Cisco switch, one containing CDP neighbor information
(with keys "local_interface", "neighbor" and "neighbor_interface") and the
other from a listing of interfaces on the switch. I want to use the
presence of a combination of the "neighbor" and "neighbor_interface" values
(from the CDP neighbor array) in the interface list array as a condition on
the running of a task.
The playbook currently looks that below.

The last task fails as below
TASK [Create interface description statements where needed]
************************************************************

nThe offending line appears to be:\n\n register: int_stat\n - name:

Any tips on how to proceed?
Do as the warning say, remove {{ }}. So something like this might work
when: int_stat.response | search(cdp_nei.response.item.neighbor ~ "_" ~
cdp_nei.response.item.local_interface)
