Approach

How did you do it?

1. Add t0-mclag-16 or t0-mclag topologies.
   ./testbed-cli.sh add-topo vms-t0-mclag-16 password.txt
   add_topo_mclag-16.txt

2. The default configuration is deployed separately on each device, using the additional parameter dut_no.
   ansible-playbook -i lab config_sonic_basedon_testbed.yml -l sonic-dut-01 -e vm_base="VM0300" -e topo=t0-mclag-16 -e deploy=True -e save=True -e save=True -e testbed_name=vms-t0-mclag-16 -e dut_no=1
   generate_configuration_for_dut1.txt
   ansible-playbook -i lab config_sonic_basedon_testbed.yml -l sonic-dut-02 -e vm_base="VM0300" -e topo=t0-mclag-16 -e deploy=True -e save=True -e testbed_name=vms-t0-mclag-16-dut2 -e dut_no=2

How did you verify/test it?
