本稿はyoutubeにあったVIRLを使ったFabricpath構築のデモ動画を参考にしています。
https://www.youtube.com/watch?v=zIVY7OLEbyk
[検証環境]
・FabricpathはSPINE 2台(nx-osv-1, nx-osv-2)、LEAF 3台(nx-osv-3, nx-osv-4, nx-osv-5)で構築
・Fabricpath内はvlan 55 (10.1.55.0/24), vlan 99 (10.1.99.0/24)の通信のみ許可
・nx-osv-3にはVLAN 55内に属すServer1 (10.1.55.1)、nx-osv-5にはVLAN99に属すServer2 (10.1.99.1)を配置
[検証項目]
・Fabricpathで通信ができること (vlan 55, vlan 99が通信可であること)
・FabricpathでVLANルーティングができること (vlan 55に属すserver1とvlan 99に属すserver2が通信できること)
１．Maestoroでセットアップ
①nx-os 5台とserver 2台を配置＆結線
②[Configuration] -> [Build initial Configration]をクリック
→これを実行しないとServerにアクセスできません。
上記が全て完了したら「Launch Simulation」ボタンを押下
VIRL Web UIで見ると下図の通り
２．NW機器設定
2-0．不要なMAC情報を消去する
・VIRLのNX-OSvはデフォルトでe2/1-48に不要なMAC情報が入っているので消去
設定要否：[要]nx-osv-1 [要]nx-osv-2 [要]nx-osv-3 [要]nx-osv-4 [要]nx-osv-5
int e2/1-48
no mac-address
exit
2-1．FabricPath利用を有効にする
・ライセンス猶予期間のイネーブル化 (license grace-period)
・FabricPath フィーチャ セットをインストール (install feature-set fabricpath)
・FabricPath フィーチャ セットを有効化 (feature-set fabricpath)
設定要否：[要]nx-osv-1 [要]nx-osv-2 [要]nx-osv-3 [要]nx-osv-4 [要]nx-osv-5
license grace-period
install feature-set fabricpath
feature-set fabricpath
・ライセンスの利用状況を確認 (show license usage)
・フィーチャーセットでfabricpathが利用可能か確認 (show feature-set)
nx-osv-1(config)# show license usage

2.2. Fabricpathで許可するVLAN設定
・今回、VLAN 55, 99を利用するのでfabricpathモードでその設定
設定要否：[要]nx-osv-1 [要]nx-osv-2 [要]nx-osv-3 [要]nx-osv-4 [要]nx-osv-5

exit
2.3. SpineのFabricpathインターフェース設定
・nx-osv-1とnx-osv-2のスイッチポートをfabricpathモードに設定
設定要否：[要]nx-osv-1 [要]nx-osv-2 [否]nx-osv-3 [否]nx-osv-4 [否]nx-osv-5
int e2/1-3

2.4. LeafのFabricpathインターフェース設定
・nx-osv-3とnx-osv-4とnx-osv-5のスイッチポートをfabricpathモードに設定

2.5. LeafのVLANインターフェース設定
・[server-1]を収容するnx-osv-3と[server-2]を収容するnx-osv-5のアドレス設定
設定要否：[否]nx-osv-1 [否]nx-osv-2 [要]nx-osv-3 [否]nx-osv-4 [要]nx-osv-5

2.6. サーバ収容のインターフェース設定
・[server-1]を収容するnx-osv-3と[server-2]を収容するnx-osv-5のインターフェース設定
設定要否：[否]nx-osv-1 [否]nx-osv-2 [要]nx-osv-3 [否]nx-osv-4 [要]nx-osv-5
