Inter-AS mVPN Option C Pattern-3 - ASBRにRR機能を移動-StaticRPを設定して、SSM用のMDT SAFIを削除

まず最初に

この検証内容は、2011年に MPLS VPN についてラボで確認した時の結果をローカルのwikiサーバーに保存していました。その後、誰かの参考になったのかどうかは分からないのですが、もうwikiサーバーも動いていませんので、誰もこの内容を見ることもないと思います。でも、最近になって自分でも見直すことがありましたので、少しでも参考になればと思い、こちらにアップすることにしました。

Topology

Figure-2

• 各ASでStatic RPを使用。(SSMは使用しない)
• 各ルータのloopbackアドレスをAS間でBGPを使用してアドバタイズ

- R1-R2間でmsdp peerを設定
