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

 

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

例として、Geneve カプセル化による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 ノードと Compute 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。
また、下例で eth1 の方は IP なしでインターフェースを UP しています。
* IP なしでのインターフェース UP の設定はこちらの [1] を参照

[1] Network ノードと Compute ノードの両方でブリッジマッピングを設定しておきます。
# ブリッジ作成 (名称は任意)

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環境に置き換え

root@network:~#
ovs-vsctl add-port br-eth1 eth1
# ブリッジと [physnet1] をマッピング ([physnet1] の名称は任意)

root@network:~#
ovs-vsctl set open . external-ids:ovn-bridge-mappings=physnet1:br-eth1

[2] 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。
