# == Class: tripleo::profile::base::neutron::server
#
# Neutron server profile for tripleo
#
# === Parameters
#
# [*bootstrap_node*]
# (Optional) The hostname of the node responsible for bootstrapping tasks
# Defaults to hiera('bootstrap_nodeid')
#
# [*step*]
# (Optional) The current step in deployment. See tripleo-heat-templates
# for more details.
# Defaults to hiera('step')
#
# [*l3_ha_override*]
# (Optional) Override the calculated value for neutron::server::l3_ha
# by default this is calculated to enable when DVR is not enabled
# and the number of nodes running neutron api is more than one.
# Defaults to '' which aligns with the t-h-t default, and means use
# the calculated value. Other possible values are 'true' or 'false'
#
# [*l3_nodes*]
# (Optional) List of nodes running the l3 agent, used when no override
# is passed to l3_ha_override to calculate enabling l3 HA.
# Defaults to hiera('neutron_l3_short_node_names') or []
# (we need to default neutron_l3_short_node_names to an empty list
# because some neutron backends disable the l3 agent)
#
# [*dvr_enabled*]
# (Optional) Is dvr enabled, used when no override is passed to
# l3_ha_override to calculate enabling l3 HA.
# Defaults to hiera('neutron::server::router_distributed') or false
