OpenStack Rocky : Neutron ネットワークを構成する (VXLAN)
2018/08/31
 
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 ノードが二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。

                                    eth1|(UP with no IP)

[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
# 130行目:tenant_network_types に値を追記

[ml2]
type_drivers = flat,vlan,gre,vxlan
tenant_network_types =
vxlan
# 181行目:追記

[ml2_type_flat]
flat_networks = physnet1
# 235行目:追記

[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

[root@network ~]#
ovs-vsctl add-port br-eth1 eth1

[root@network ~]#
vi /etc/neutron/plugins/ml2/ml2_conf.ini
# 130行目:tenant_network_types に値を追記

[ml2]
type_drivers = flat,vlan,gre,vxlan
tenant_network_types =
vxlan
# 181行目:追記

[ml2_type_flat]
flat_networks = physnet1
# 235行目:追記

[ml2_type_vxlan]
vni_ranges = 1:1000
[root@network ~]#
vi /etc/neutron/plugins/ml2/openvswitch_agent.ini
# 118行目:追記

[agent]
tunnel_types = vxlan
l2_population = True
prevent_arp_spoofing = True
# 196行目:追記 ( local_ip はこのノードのローカルIPを指定)

[ovs]
local_ip = 10.0.0.50
bridge_mappings = physnet1:br-eth1
[root@network ~]#
for service in dhcp-agent l3-agent metadata-agent openvswitch-agent; do
systemctl restart neutron-$service
done
# Firewalld 稼働中の場合は停止

[root@network ~]#
systemctl stop firewalld

[root@network ~]#
systemctl disable firewalld

[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
# 130行目:tenant_network_types に値を追記

[ml2]
type_drivers = flat,vlan,gre,vxlan
tenant_network_types =
vxlan
# 181行目:追記

[ml2_type_flat]
flat_networks = physnet1
# 235行目:追記

[ml2_type_vxlan]
vni_ranges = 1:1000
[root@node01 ~]#
vi /etc/neutron/plugins/ml2/openvswitch_agent.ini
# 118行目:追記

[agent]
tunnel_types = vxlan
l2_population = True
prevent_arp_spoofing = True
# 196行目:追記 ( local_ip はこのノードのローカルIPを指定)

[ovs]
local_ip = 10.0.0.51
[root@node01 ~]#
systemctl restart neutron-openvswitch-agent
# Firewalld 稼働中の場合は停止

[root@node01 ~]#
systemctl stop firewalld

[root@node01 ~]#
systemctl disable firewalld

[4] 仮想ルータを作成します。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。
# 仮想ルーター作成

[root@dlp ~(keystone)]#
openstack router create router01
