This script executes multiple scripts which setup the hosts.
In our setup we'll only have two hosts, but this can be extended to other
hosts as well.
Information needed to do so is:
This script executes the helper scripts to
- The interface name which is connected to the switch
- MAC address of the interface
- Unused IP address
- And take a look at the appendix under "Adding new node"
- Setup Namespaces
- Setup Interfaces
- Setup IP Addresses
- Setup ARP Table Entries
