OpenStack Caracal : Neutron ネットワークを構成する (VXLAN)2024/08/06

 

OpenStack Network Service(Neutron)による仮想ネットワークの構成です。

例として、VXLAN タイプのネットワークを構成します。
事前に以下のように Control ノードNetwork ノードCompute ノードの 各 Neutron サービスノードを構築済みであることが前提です。

また、当例では Network ノードが 2 つのネットワークインターフェースを持っているものとします。

[1] Control ノードで以下のように設定変更します。
[root@dlp ~(keystone)]#
vi /etc/neutron/plugins/ml2/ml2_conf.ini
# 最終行付近 : [tenant_network_types] に値を追記

[ml2]
type_drivers = flat,vlan,gre,vxlan
tenant_network_types =
vxlan
# 最終行に追記

[ml2_type_flat]
flat_networks = physnet1

[ml2_type_vxlan]
vni_ranges = 1:1000

[root@dlp ~(keystone)]#
systemctl restart neutron-server

[2] Network ノードで以下のように設定変更します。
# ブリッジ追加

[root@network ~]#
ovs-vsctl add-br br-eth1
# 追加したブリッジのポートに [eth1] を追加
# [eth1] は環境によって異なるため自身の名称に置き換え

[root@network ~]#
ovs-vsctl add-port br-eth1 eth1
[root@network ~]#
vi /etc/neutron/plugins/ml2/ml2_conf.ini
# 最終行付近 : [tenant_network_types] に値を追記

[ml2]
type_drivers = flat,vlan,gre,vxlan
tenant_network_types =
vxlan

mechanism_drivers = openvswitch
extension_drivers = port_security,qos
# 最終行に追記

[ml2_type_flat]
flat_networks = physnet1

[ml2_type_vxlan]
vni_ranges = 1:1000

[root@network ~]#
vi /etc/neutron/plugins/ml2/openvswitch_agent.ini
# 最終行に追記

[agent]
tunnel_types = vxlan
prevent_arp_spoofing = True

[ovs]
# [local_ip] には当ノードのローカル IP アドレスを指定
local_ip = 10.0.0.50
bridge_mappings = physnet1:br-eth1

[root@network ~]#
systemctl restart neutron-dhcp-agent neutron-l3-agent neutron-metadata-agent neutron-openvswitch-agent
# Firewalld 稼働中の場合は VXLAN ポート許可

[root@network ~]#
firewall-cmd --add-port=4789/udp

[root@network ~]#
firewall-cmd --runtime-to-permanent

[3] Compute ノードで以下のように設定変更します。
[root@node01 ~]#
vi /etc/neutron/plugins/ml2/ml2_conf.ini
# 最終行付近 : [tenant_network_types] に値を追記

[ml2]
type_drivers = flat,vlan,gre,vxlan
tenant_network_types =
vxlan

mechanism_drivers = openvswitch
extension_drivers = port_security,qos
# 最終行に追記

[ml2_type_flat]
flat_networks = physnet1

[ml2_type_vxlan]
vni_ranges = 1:1000

[root@node01 ~]#
vi /etc/neutron/plugins/ml2/openvswitch_agent.ini
# 最終行に追記

[agent]
tunnel_types = vxlan
prevent_arp_spoofing = True

[ovs]
# [local_ip] には当ノードのローカル IP アドレスを指定
local_ip = 10.0.0.51

[root@node01 ~]#
systemctl restart neutron-openvswitch-agent
# Firewalld 稼働中の場合は VXLAN ポート許可

[root@node01 ~]#
firewall-cmd --add-port=4789/udp

[root@node01 ~]#
firewall-cmd --runtime-to-permanent

[4] 仮想ルーターを作成します。作業場所はどこでもよいですが、当例では Control ノード上で作業します。
