先日リリースされた vJunos-switch について、BGP EVPN VXLAN の検証を実施しました。

このページにラボシナリオとして、コンフィグや確認コマンド、疎通確認のポイントなどをまとめています。
==目的==
レイヤ 3 インターフェース経由で、同一サブネットの通信が可能であること。
==検証環境==
'''EVE-NG Community Edition'''

'''Juniper vJunos-switch 23.2R1.14'''

'''Cisco CSR1000V 17.3.4a'''
==構成図==
*CSR1000V : CSR01,02

==コンフィギュレーション==
ここではプロトコル・ホスト別にコンフィギュレーションを簡単に解説します。

自分でコンフィグを組んでみたい人向けに、デフォルトでは表示しません。

このページのリファレンスに記載した、Cisco のサイトを参考に設定してみると良いでしょう。
