## 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.

# EXAMPLE INTERFACE FILE
# 1293 - HOST_NET (Ignore This. It's the native VLAN.)
# 2176 - CONTAINER_NET
# 1998 - OVERLAY_NET
# 2144 - STORAGE_NET
# 2146 - GATEWAY_NET (VM Provider Network. Ignore this. OpenStack will tag for us.)

## Physical interface, could be bond. This only needs to be set once for the physical device
auto eth0
iface eth0 inet manual

auto eth1
iface eth1 inet manual


## Vlan tagged interface, this should be physical interface along with the vlan tag
# The vlan tag number should reflect your already setup vlans.
