# This script simulates 2 chassis connected to a physical switch,
# which we call "physnet1". We have two logical ports, one on each hypervisor,
# that OVN will connect to physnet1.
#
# The way to accomplish this in OVN is to create a logical switch for each
# logical port.  In addition to the normal logical port, each logical switch
# has a special "localnet" port, which represents the connection to physnet1.
#
# In this setup we see the view of this environment from one of the hypervisors.
