概要
EIGRPによる基本的なルーティングを行う演習です。条件に基づいて設定していますが、設定ミスがあります。設定ミスの切り分けと修正を行います。
ネットワーク構成
設定条件
- 図 EIGRPネットワーク構成の通りに各ルータでEIGRPの設定を行なってください。なお、フレームリレーにはブロードキャスト/マルチキャストパケットを送信できないようにしています。また、インタフェースに設定されているIPアドレスのサブネットマスクでルートをアドバタイズできるようにします。
- フレームリレーのインタフェースでは、EIGRPパケットが利用する帯域幅が25%になるようにしてください。また、ネイバーの障害検出を10秒以内にできるようにしてください。
- フレームリレー上でMD5のネイバー認証を行います。パスワードは任意の文字列で設定してください。
- R3はR6にEIGRPクエリーを送信しないようにしてください。
- R4でデフォルトルートをEIGRPでアドバタイズし、インターネットにアクセスできるようにします。
- ネットワーク構成上のすべてのIPアドレスに接続性があることを確認してください。
初期設定
条件に基づいてEIGRPの設定を行っています。しかし、5つの設定ミスが含まれています。設定ミスによるトラブルの症状は次のとおりです。
- R1-R2間のネイバーを確立できません。
- R2-R5間のネイバーを確立できません。
- フレームリレー上でEIGRPルートを正しく送受信できていません。
- R6のLoopback0のIPアドレスへの通信ができません。
- インターネットへの通信ができません。

EIGRP基本設定 トラブルシューティング
1. neighborコマンド
フレームリレー上でマルチキャストパケットを送信できないので、EIGRP Helloパケットをユニキャストで送信するためにneighborコマンドが必要です。R1でR2に対するneighborコマンドが設定されていないので、R1-R2間のネイバーを確立できません。
