2024-06-16-vJunos-switch BGP-EVPN-VXLAN 機能検証のソースを表示

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
*vJunos-switch : vEX01,02
[[ファイル:20240616 vJunos-switch Diagram.png|代替文=20240616 vJunos-switch Diagram|なし|フレーム|20240616 vJunos-switch Diagram]]vEX 間はルーティングを動作させて、CSR01 , 02 間で同一セグメント内の通信可否を確認します。

==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、Juniper や日商エレのサイトを参考に設定してみると良いでしょう。

Junos は MX / QFX / EX で共通ですが、EVPN の場合使用できるコマンドにかなり違いがありました。

vJunos-switch は EX9214 模擬ですが、bridge 系は動作しないと見て良いようです。

ネットを調べていると MX の EVPN 設定ガイドが見つかりますが、そのまま使えるコンフィグはほとんど無い印象です。


また Cisco 系では vlan-based が使用可能ですが、Juniper のデフォルトは vlan-aware bundle になるようで、意識してコンフィグできるようになりたいところです。(筆者もわかっているとは言い難い)

今回は Cisco との接続を今後行う可能性を考慮して、vlan-based で設定しました。
