An Ansible role to configure network interfaces

Define dhcp, static, and manual settings
Create VLAN, bonds, bridges, and interfaces
Create Open vSwitch bridges, bonds, and interfaces

This role is a fork of config-interfaces, however both roles are not interchangeable. To replace one role with the other, one would have to update their inventory.

Requirements

See Example Playbook for examples of how to define specific network configurations.

NOTE: If creating Open vSwitch configurations you will need to use the ansible-openvswitch Ansible role

Role Variables

defaults/main.yml

Dependencies

If interface is wireless you will need to define as such as well as provide the SSID and key.
