前提・実現したいこと
Cisco C841M-4X-JSEC/K9 を GW Router として使いたいのですが Routing してくれません。
(厳密には WAN I/F の先にもう1台ルータっぽい何かがいるのでGWとはいいがたい)
IPを振り終えPINGを行おうとしたところ、拡張PINGにてエラーが発生しました。
NW構成図は Qiita に纏めてなぐり書き。。。
なんとか LAN から出て 返ってこれる ようにしたいです。
発生している問題・エラーメッセージ

試したこと
- Gi0/5 抜き差し
- Gi0/0 抜き差し
no router ospf 1
→ 戻しno router bgp 3038
→ 戻し- vlan 80 & SVI 作成 → 戻し

DGWにping 行うと そもそもDGWに届いていない事が判明(Gi0/5からはOKだが問題はそれ以外)(構成変わらずのまま)
