###前提
ルーティングプロトコル「EIGRP」の勉強をしており、Catalyst3560を用い、
下記の環境下での検証を行っております。その際、動作が上手くいかなかった為、今回質問させていただきました。
どの様に改善するとホスト同士の通信が可能となるのでしょうか。
手あたり次第対応いたしましたが、通信できず詰まってしまった為、ご教示いただければ幸いです。
sh ver / sh run を記載したため大変見辛くなっており恐れ入りますが、何卒宜しくお願い致します。
###実現したいこと
このような環境下でEIGRPを用いて、ホスト同士の通信を成功させる。
(Ripv1・Ripv2では成功しております)
###発生している問題・エラーメッセージ
-
上図の矢印のようにPingを飛ばした時、点線以降のインターフェースへの着弾失敗(Destination host unreachable.)
-
また[PC2]と[SW3]の間に、[SW4][SW5]…とデバイスを追加した場合、同様な距離で「Destination host unreachable.」
(簡略図。左側からPingを飛ばす。〇:着弾成功、×:着弾失敗)
[SW2]out〇→in〇[SW3]out〇→in〇[SW4]out×→in×[SW5]
[SW3]out〇→in〇[SW4]out〇→in〇[SW5]out×→in×[PC2]

###試したこと
- スプリットホライズン無効化
- それぞれの FastEthernet に関して
L2にした場合(swichportにし、VlanからIPアドレスを割り振る)
L3にした場合(no swichportにし、インターフェースへ直接IPアドレスを割り振る)
それぞれ検証済み
###補足情報(言語/FW/ツール等のバージョンなど)
- 使用ツール
tera term
- OS
Microsoft Windows 10 Pro
###備考
- IOSのライセンスがIP Baseなので、EIGRPの機能制限によりこの様な挙動をしてしまうのでしょうか。。
