+# Neutron DHCP agent puppet resource
+
+Setups Neutron DHCP agent.
+
+# Parameters
+
+https://github.com/openstack/puppet-neutron/blob/5.1.0/manifests/agents/dhcp.pp
+
+
+ ``package_ensure``
+   (optional) Ensure state for package. Defaults to 'present'.
+
+ ``debug``
+   (optional) Show debugging output in log. Defaults to false.
+
+ ``state_path``
+   (optional) Where to store dnsmasq state files. This directory must be
+   writable by the user executing the agent. Defaults to '/var/lib/neutron'.
+
+ ``resync_interval``
+   (optional) The DHCP agent will resync its state with Neutron to recover
+   from any transient notification or rpc errors. The interval is number of
+   seconds between attempts. Defaults to 30.
+
+ ``interface_driver``
+   (optional) Defaults to 'neutron.agent.linux.interface.OVSInterfaceDriver'.
+
+ ``dhcp_driver``
+   (optional) Defaults to 'neutron.agent.linux.dhcp.Dnsmasq'.
+
+ ``root_helper``
+   (optional) Defaults to 'sudo neutron-rootwrap /etc/neutron/rootwrap.conf'.
+   Addresses bug: https://bugs.launchpad.net/neutron/+bug/1182616
+   Note: This can safely be removed once the module only targets the Havana release.
+
+ ``use_namespaces``
+   (optional) Allow overlapping IP (Must have kernel build with
+   CONFIG_NET_NS=y and iproute2 package that supports namespaces).
+   Defaults to true.
+
+ ``dnsmasq_config_file``
+   (optional) Override the default dnsmasq settings with this file.
+   Defaults to undef
+
+ ``dhcp_delete_namespaces``
+   (optional) Delete namespace after removing a dhcp server
+   Defaults to false.
+
+ ``enable_isolated_metadata``
+   (optional) enable metadata support on isolated networks.
+   Defaults to false.
+
+ ``enable_metadata_network``
+   (optional) Allows for serving metadata requests coming from a dedicated metadata
+   access network whose cidr is 169.254.169.254/16 (or larger prefix), and is
+   connected to a Neutron router from which the VMs send metadata request.
+   This option requires enable_isolated_metadata = True
+   Defaults to false.
