先に結論
Softbank回線のほうがいいんじゃね・・・？
試験した日
めちゃくちゃ暑かった。溶ける... (↓↓↓switchbotで室温湿度測定↓↓↓)
Ping 実施してみた
Docomo側, SB側ともに 下記条件にて Ping を実施した
| 宛先 | 8.8.8.8(google.dns) |
| 回数 | 10 x 10 回 |
| MTU | 1422 |
| dfBit | On |
| 送信元デバイス | Cisco 891FJ (有線LAN(Gi8)接続) |
MTU = 1422 とした理由
SB側でdf-bit有効化した状態でPing疎通可能な値が1422だったため。なぜかはしらん。
