CCNAはどういうものは気になって、CISCO 891FJルーターを買って、楽天ひかりでPPPoE接続してしまった（初めての投稿 ）

落ち込み日々に気を逸らすため、CCNAを勉強し、疲れた心を癒す。
------------------
まあまあ、CCNAはこの程度だね。:sunny:

:::note warn
前提条件：
１：IOSバージョン 15.5以降
２：楽天ひかりを使っている
３：サンプルコードは、IPv6（DS-Lite）の対応途中のため
　　役立つのは、PPPoE関連の設定のみ

下記は、実際の設定コマンド：

IPv4 over IPv6(DS-Lite)の接続も試しているが、どうもうまく行かず、落ち込んでいる状態でござる。
