# == Class: tripleo::profile::base::neutron
#
# Neutron server profile for tripleo
#
# === Parameters
#
# [*step*]
# (Optional) The current step of the deployment
# Defaults to hiera('step')
#
# [*rabbit_hosts*]
# list of the rabbbit host IPs
# Defaults to hiera('rabbitmq_node_ips')
#
# [*rabbit_port*]
# IP port for rabbitmq service
# Defaults to hiera('neutron::rabbit_port', 5672
#
# [*dhcp_agents_per_network*]
# (Optional) TripleO configured number of DHCP agents
# to use per network. If left to the default value, neutron will be
# configured with the number of DHCP agents being deployed.
# Defaults to undef
#
# [*dhcp_nodes*]
# (Optional) List of nodes running the DHCP agent. Used to
# set neutron's dhcp_agents_per_network value to the number
# of available agents.
# Defaults to hiera('neutron_dhcp_short_node_names') or []
