送信元CEルータのステータスを確認する際に、このルータにはVRF(Virtual Route Forwarding)がなく、MPLS対応ではないため、RIB(Routing Information Base)、CEF(Cisco Express Forwarding)、およびBGPを確認する必要があります。次の出力では、BGPを介して宛先サブネット172.16.1.0/24に既知のルーティングエントリがあり、インターフェイスGigabitEthernet0/0を介して到達可能であることがわかります。

この時点で、MP-BGPコントロールプレーンには宛先プレフィクスとLDPおよびVPNv4ラベル{24001 16}がそれぞれ割り当てられています。このトラフィックの出口インターフェイスはGi0/0/0/4のようであり、トラフィックを転送する必要のあるネクストホップは10.10.10.1です。ただし、優先される出口インターフェイスを確認する別のオプションはありますか。次に、MPLS転送テーブルまたはLFIB(Label Forwarding Information Base;ラベル転送情報ベース)を調べます。show mpls forwardingコマンドを使用すると、2つのエントリが10.10.10.1の宛先(PE1からのループバック0)に向けて表示されます。一方のパスはGi0/0/0/4の発信インターフェイス(Loopback0)とネクストホップ10.0.0.16(ルータP5)を持ち、課された発信ラベルが24001のGi0/0/0/0/3を通るパスはネクストホップ1113(ルータP6)と223の発信発信ラベルをを持持持します。

上記の出力から、プレフィックス10.10.10.1/32のLFIBエントリでは、発信ラベルとして「Pop」が表示されていることがわかります。これは、このルータがPenultimate Hop Popping(PHP)であることを意味します。また、LFIB情報に基づいてトラフィックをGi0/0/0/1経由で送信する必要があることも示しています。これはCEFを確認しながら確認することもできます。次のCEF exact-route出力は、課されたラベルとして暗黙的なヌルラベルを示しています。これも、Gi0/0/0/1に接続されたネクストホップがラベルスイッチパスの最後のルータであり、宛先サイト(CE-WEST)に面しているPEであるためです。これは、ルータP5がパケットに別のラベルを付けずに削除している理由でもあります。このプロセスのおかげで、出力ルータPE1はLDPラベルのないパケットを受信することになります。
