Puppet Class: neutron::agents::ml2::linuxbridge

Defined in:
manifests/agents/ml2/linuxbridge.pp

Overview

Class: neutron::agents::ml2::linuxbridge

Setups Linuxbridge Neutron agent for ML2 plugin.

Parameters

package_ensure

(optional) Package ensure state. Defaults to ‘present’.

enabled

(required) Whether or not to enable the agent. Defaults to true.

tunnel_types

(optional) List of types of tunnels to use when utilizing tunnels. Supported tunnel types are: vxlan. Defaults to an empty list.

local_ip

(optional) Local IP address to use for VXLAN endpoints. Required when enabling tunneling. Defaults to false.

vxlan_group

(optional) Multicast group for vxlan interface. If unset, disables VXLAN multicast mode. Should be an Multicast IP (v4 or v6) address. Default to ‘224.0.0.1’.

vxlan_ttl

(optional) TTL for vxlan interface protocol packets.. Default to undef.

vxlan_tos

(optional) TOS for vxlan interface protocol packets.. Defaults to undef.

polling_interval

(optional) The number of seconds the agent will wait between polling for local device changes. Defaults to 2.

l2_population

(optional) Extension to use alongside ml2 plugin’s l2population mechanism driver. It enables the plugin to populate VXLAN forwarding table. Defaults to false.

physical_interface_mappings

(optional) List of <physical_network>:<physical_interface> tuples mapping physical network names to agent’s node-specific physical network interfaces. Defaults to empty list.

firewall_driver

(optional) Firewall driver for realizing neutron security group function. Defaults to ‘neutron.agent.linux.iptables_firewall.IptablesFirewallDriver’.

Parameters:

  • package_ensure (Any) (defaults to: 'present')
  • enabled (Any) (defaults to: true)
  • tunnel_types (Any) (defaults to: [])
  • local_ip (Any) (defaults to: false)
  • vxlan_group (Any) (defaults to: '224.0.0.1')
  • vxlan_ttl (Any) (defaults to: false)
  • vxlan_tos (Any) (defaults to: false)
  • polling_interval (Any) (defaults to: 2)
  • l2_population (Any) (defaults to: false)
  • physical_interface_mappings (Any) (defaults to: [])
  • firewall_driver (Any) (defaults to: 'neutron.agent.linux.iptables_firewall.IptablesFirewallDriver')
