./testbed-cli.sh add-topo vms-sonic-dut ~/.password
in add_topo function is doing (line 218)
ansible-playbook fanout_connect.yml -i veos --limit server_1 --vault-password-file=password.txt -e dut=sonic-dut -vvvv

fanout_connect.yaml on line 28 does
include_tasks: roles/fanout/tasks/rootfanout_connect.yml

and that calls on line 48
action: apswitch template=roles/fanout/templates/arista_7260_connect.j2

in ansible/lab file I specified os: sonic for both fanout switches (root and leaf)

what file do I need to configure or what needs to be done in order for testbed-cli.sh to work with a sonic fanout switch (leaf and root)
