Persist iptables rules 
We configured iptables rules but did not persist them.
This meant that rules would be flushed when restarting iptables or
the instance.

README.rst

Configures a VXLAN virtual network overlay through an openvswitch network bridge between a 'switch' node and 'peer' nodes.

This allows members of the bridge to communicate with each other through the virtual network.

By default, this role will:

  • Install and start openvswitch
  • Set up a br-infra bridge on all nodes
  • Set up the connectivity between the switch and the peer with a virtual port
  • Set up an ip address on the bridge interface:
172.24.4.1/23 # switch node
172.41.4.2/23 # first peer
172.41.4.3/23 # second peer
...

Role requirements

This role requires and expects two groups to be set up in the Ansible host inventory in order to work:

  • switch (the node acting as the switch)
  • peers (nodes connected to the virtual switch ports)
