# Configure the neutron server to use the ML2 plugin.
# This configures the plugin for the API server, but does nothing
# about configuring the agents that must also run and share a config
# file with the OVS plugin if both are on the same machine.
#
# === Parameters
#
# [*type_drivers*]
# (optional) List of network type driver entrypoints to be loaded
# from the neutron.ml2.type_drivers namespace.
# Could be an array that can have these elements:
# local, flat, vlan, gre, vxlan
# Defaults to ['local', 'flat', 'vlan', 'gre', 'vxlan'].
#
# [*tenant_network_types*]
# (optional) Ordered list of network_types to allocate as tenant networks.
# The value 'local' is only useful for single-box testing
# but provides no connectivity between hosts.
# Should be an array that can have these elements:
# local, flat, vlan, gre, vxlan
# Defaults to ['local', 'flat', 'vlan', 'gre', 'vxlan'].
#
# [*mechanism_drivers*]
# (optional) An ordered list of networking mechanism driver
# entrypoints to be loaded from the neutron.ml2.mechanism_drivers namespace.
# Should be an array that can have these elements:
# logger, test, linuxbridge, openvswitch, hyperv, ncs, arista, cisco_nexus,
# l2population.
# Default to ['openvswitch', 'linuxbridge'].
#
# [*flat_networks*]
# (optional) List of physical_network names with which flat networks
# can be created. Use * to allow flat networks with arbitrary
# physical_network names.
# Should be an array.
# Default to *.
#
# [*network_vlan_ranges*]
# (optional) List of <physical_network>:<vlan_min>:<vlan_max> or
# <physical_network> specifying physical_network names
# usable for VLAN provider and tenant networks, as
# well as ranges of VLAN tags on each available for
# allocation to tenant networks.
# Should be an array with vlan_min = 1 & vlan_max = 4094 (IEEE 802.1Q)
# Default to empty.
#
# [*tunnel_id_ranges*]
# (optional) Comma-separated list of <tun_min>:<tun_max> tuples
# enumerating ranges of GRE tunnel IDs that are
# available for tenant network allocation
# Should be an array with tun_max +1 - tun_min > 1000000
# Default to empty.
#
# [*vxlan_group*]
# (optional) Multicast group for VXLAN.
# Multicast group for VXLAN. If unset, disables VXLAN enable sending allocate
# broadcast traffic to this multicast group. When left unconfigured, will
# disable multicast VXLAN mode
# Should be an Multicast IP (v4 or v6) address.
# Default to 'None'.
#
# [*vni_ranges*]
# (optional) Comma-separated list of <vni_min>:<vni_max> tuples
# enumerating ranges of VXLAN VNI IDs that are
# available for tenant network allocation.
# Min value is 0 and Max value is 16777215.
# Default to empty.
#
# [*enable_security_group*]
# (optional) Controls if neutron security group is enabled or not.
# It should be false when you use nova security group.
# Defaults to true.
