Doc Type: Enhancement
Doc Text:
This release introduces four parameters that govern the default overcloud neutron tenant network behavior: --neutron-network-type, --neutron-tunnel-types, --neutron-disable-tunneling, and --neutron-network-vlan-ranges. The default is to provide GRE types and tunnels for overcloud tenant networks. If the --neutron-network-type is specified as 'vlan', you can also set the --neutron-network-vlan-ranges parameter, which governs the range of VLAN IDs to be allocated to overcloud Neutron tenant networks (defaults to "datacenter:1:1000", where "datacenter" must be the name of the Neutron physical network where the VLANs will be allocated). If exclusively specifying 'vlan' as the network type, then --neutron-disable-tunneling must also be specified (examples below). If the --neutron-network-type is specified as 'gre' or 'vxlan' (or both), then the corresponding --neutron-tunnel-types must also be enabled (examples below). Furthermore, when specifying the 'gre' or 'vxlan' network types, you can further set the related --neutron-tunnel-id-ranges and --neutron-vni-ranges parameters that govern the GRE or VXLAN tunnel IDs respectively. These are to be made available for the tenant networks. Examples: * Specify the 'vxlan' type for overcloud tenant networks: openstack overcloud deploy --plan overcloud --control-scale 3 --compute-scale 2 --neutron-network-type "vxlan" --neutron-tunnel-types "vxlan" * Specify both 'gre' and 'vxlan' overcloud tenant networks: openstack overcloud deploy --plan overcloud --control-scale 3 --compute-scale 2 --neutron-network-type "gre,vxlan" --neutron-tunnel-types "gre,vxlan" * Specify the 'vlan' type for overcloud tenant networks, as well as the VLAN ranges: openstack overcloud deploy --plan overcloud --control-scale 3 --compute-scale 2 --neutron-network-type "vlan" --neutron-disable-tunneling --neutron-network-vlan-ranges "datacenter:3:3000" These parameters default to the following values when not specified at deployment time, and may be deemed restrictive or unsuitable for a given deployment scenario: --neutron-network-type # default 'gre' --neutron-tunnel-types # default 'gre' --neutron-disable-tunneling # defaults to tunneling being enabled --neutron-network-vlan-ranges # 'datacenter:1:1000' After deployment, you can verify that the following are set in the Neutron configuration logs on a controller node; the values here should correspond to those specified during the deployment as shown above: grep -rni 'tunnel_types\|network_type\|enable_tunneling\|vlan_ranges' /etc/neutron/* /etc/neutron/plugin.ini:14:tenant_network_types = vlan /etc/neutron/plugin.ini:72:network_vlan_ranges =datacenter:3:3000 /etc/neutron/plugins/openvswitch/ovs_neutron_plugin.ini:54:enable_tunneling=False /etc/neutron/plugins/ml2/ml2_conf.ini:14:tenant_network_types = vlan /etc/neutron/plugins/ml2/ml2_conf.ini:72:network_vlan_ranges =datacenter:3:3000 Also, you can create a network in overcloud Neutron and inspect it; for example, on the undercloud: $ source overcloudrc $ neutron net-create "default" $ neutron net-show default ... | provider:network_type | vlan | | provider:physical_network | datacenter | | provider:segmentation_id | 3 | ...

Description Giulio Fidente 2015-06-11 00:06:39 UTC
We should make it possible for users to select amongst gre, vxlan or vlan for the tenant networks tunneling. Currently gre is used by default.

To use vxlan:

  NeutronNetworkType: vxlan
  NeutronTunnelTypes: vxlan

To use vlan:

  NeutronNetworkType: vlan
  NeutronEnableTunnelling: false
  NeutronNetworkVLANRanges: datacentre:1:1000


- 'datacentre' must be the name of the neutron physical network where the vlans will be allocated (by default we have a single physical network defined in NeutronBridgeMappings)
- 1:1000 is the allocatable range

Comment 3 chris alfonso 2015-06-12 16:39:04 UTC
Gulio, please link your patch in here so we have the docs on how this works.

Comment 4 Giulio Fidente 2015-06-12 16:50:10 UTC
Following changes were pushed to make the three options working correctly in the templates: 


as per report the relevant params are:

  NeutronNetworkType: (can be gre, vxlan or vlan)
  NeutronTunnelTypes: (can be gre or vxlan)
  NeutronEnableTunnelling: (should be false when using vlan type)
  NeutronNetworkVLANRanges: datacentre:1:1000 (the neutron phys network name plus the vlan range to use)
