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
Feature                      Ins  Lic Count | Status | Expiry Date Comments
------------------------------------------------------------------------------
ENHANCED_LAYER2_PKG           No    -   In use             Grace 119D 23H

nx-osv-1(config)# show feature-set
Feature Set Name      ID        State
--------------------  --------  --------
fabricpath             2          enabled

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

vlan 55, 99
mode fabricpath
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
switchport 
switchport mode fabricpath
no shut

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
設定要否：[否]nx-osv-1 [否]nx-osv-2 [要]nx-osv-3 [要]nx-osv-4 [要]nx-osv-5

int e2/1-2
switchport 
switchport mode fabricpath
no shut

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

▼nx-osv-3

int vlan 55
ip address 10.1.55.3/24
no shut
int vlan 99
ip address 10.1.99.3/24
no shut

▼nx-osv-5

int vlan 55
ip address 10.1.55.5/24
no shut
int vlan 99
ip address 10.1.99.5/24
no shut

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

▼nx-osv-3 (vlan 55)

int eth 2/3
swichport mode access
swichport access vlan 55

▼nx-osv-5 (vlan 99)

int eth 2/3
swichport mode access
swichport access vlan 99

2.7. サーバ設定

・[server-1]と[server-2]は以下のように設定する
