NSX Advanced Load Balancer は、仮想サービスの BGP ベースのスケーリングに Quagga を使用します。したがって、BGP 構成または BGP ピアの状態をデバッグまたはチェックするには、サービス エンジンの Quagga インスタンスにログインすることが必須です。
詳細については、「VMware NSX Advanced Load Balancer CLI を使用して Quagga シェルにアクセスして使用する方法」を参照してください。
デバッグがしやすくなるよう、これらのコマンドは NSX Advanced Load Balancer Controller シェルで表示します。
