- nic_name: The name of the additional nic on which user wants to configure the ip rule.
- gateway: The gateway through which the NIC is connected to the switch.
- metric: Network metric value is a value assigned to an IP route for a network interface that indicates the cost of using that route.

Use the following command to execute the playbook:
ansible-playbook ip_rule_assignment.yml -i inventory
