フレッツVPNワイド 端末型 メッシュ IPIPトンネル 失敗事例

フレッツVPNワイド　端末型　メッシュ　IPIPトンネル　失敗事例の紹介です。

フレッツVPNワイド　端末型払い出し　メッシュ　インターネット本社から接続の場合　IPIPトンネル。
C拠点設置の際にpingが通らなくて、configをチェックしました。

C拠点側のステータスランプは消えているのに、pingが通らないという事象が発生し、原因の箇所を探りました。通信会社サポートにてトンネルの確立のチェックはしてもらえ、そこでは問題ないとの回答であったため、原因の切り分けで、センター側を疑い、箇所を見つけました。

tunnel selectとtunnel enableでひとくみ

トンネルは、tunnel selectと、tunnel enableで一組。
記述ミス。ひともじのミス！！でした。
