AWS – ルートテーブル情報の取得
概要
ルートテーブルの情報を取得する方法について記載しています。
ルートテーブル
ルートテーブルには、ネットワークトラフィックの経路を判断する際に使用される、ルートと呼ばれる一連のルールが含まれます。 VPC の各サブネットをルートテーブルに関連付ける必要があります。サブネットのルーティングは、このテーブルによってコントロールされます。1 つのサブネットは同時に 1 つのルートテーブルにしか関連付けることはできませんが、異なる複数のサブネットを 1 つのルートテーブルに関連付けることはできます。
手順
ルートテーブルの情報を取得するには次のコマンドを実行します。
aws ec2 describe-route-tablesTEXT
