Example network interface file using a single bonded interface

gistfile1.txt

## The default networking requires several bridges. These bridges were named to be informative
## however they can be named what ever you like and is adaptable to any network infrastructure
## environment. This file serves as an example of how to setup basic networking and was ONLY
## built for the purpose of being an example of an environment with a single bonded interface.

# All nodes will have some physical interface

# -------------
# The bond is not required but it can provide better throughput and redundancy.
