OpenStack Yoga : Neutron ネットワークを構成 (VXLAN)
2022/04/30
 
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。
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] を参照ください
