例

次に、内部インターフェイスからの ICMP パケットをトレースする例を示します。結果は、リバースパスの検証失敗（RPF）が原因でパケットがドロップされたことを示しています。失敗の原因は、ルーティングテーブルにあるアドレスから外部インターフェイスにトラフィックが入り、このアドレスが内部インターフェイスに関連付けられていたことにあると考えられます。同様に、未知の送信元アドレスから内部インターフェイスにトラフィックが入った場合は、一致するルート（デフォルト ルート）が外部インターフェイスを示しているため、デバイスはパケットをドロップします。

packet-tracer の bypass-checks オプションの例については、以下のフェーズで概要を示します。各シナリオでは、特定の例が想定されています。

• スポークとハブ間に IPSec トンネルが作成されない場合。

• 2 つのボックス間で IPSec トンネルをネゴシエートする必要があり、最初のパケットがトンネルの確立をトリガーします。

• IPSec ネゴシエーションが完了し、トンネルが生成されます。

• トンネルが起動すると、発信されるパケットはトンネルを介して送信されます。パケット パスで使用できるセキュリティ チェック（ACL、VPN フィルタリング..）がバイパスまたはスキップされます。

IPSec トンネルは作成されません。
