10.5. ネットワークインターフェイスレイアウトの例
以下のスニペットはコントローラーノードの NIC テンプレートの例で、コントロールグループを OVS ブリッジから分離するカスタムネットワークシナリオの設定方法を示しています。

このテンプレートは、3 つのネットワークインターフェイスを使用し、タグ付けられた複数の VLAN デバイスを、番号付きのインターフェイス (nic1
から nic3
) に割り当てます。nic2
および nic3
で、このテンプレートは、ストレージ、テナント、および外部ネットワークをホストする OVS ブリッジを作成します。その結果、以下のレイアウトが作成されます。
NIC1 (プロビジョニング)
- Provisioning / Control Plane
NIC2 および NIC3 (管理)
- Internal API
- ストレージ
- Storage Management
- Tenant Network (VXLAN トンネリング)
- Tenant VLAN / Provider VLAN
- External (パブリック API)
- External VLAN (Floating IP/SNAT)
