概要
EIGRPによる基本的なルーティングを行う演習です。フレームリレーのNBMA環境の設定を扱っています。フレームリレーはもうレガシーなWANサービスですが、DMVPNのmGREトンネルでEIGRPを利用するときに参考になります。
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
以下の内容は設定済みです。
- ホスト名
- IPアドレス
- フレームリレー接続
- R1/R2/R3でbroadcastオプションなしでframe-relay mapの設定
- スタティックルート
- R4でデフォルトルートをスタティックで設定
- NAT
- R4で192.168.X.XをE1/1のIPアドレス100.0.0.4に変換

Step2:EIGRPの確認
Step1のEIGRPの設定を確認するために、次のコマンドを利用します。
- show ip protocols
- show ip eigrp interfaces
- show ip eigrp neighbor
R1では次のような表示です。

Step3:フレームリレー上のネイバーの指定
フレームリレー上のR1-R2間、R1-R3間でEIGRPネイバーを確立できていません。この演習のフレームリレーには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。そのため、マルチキャスト224.0.0.10のHelloパケットがフレームリレーへ送信されていないからです。
マルチキャストパケットを転送できないフレームリレーネットワーク上でEIGRPネイバーを確立するために、neighborコマンドでネイバーのIPアドレスを指定します。これにより、ユニキャストでEIGRP Helloパケットを送信します。
R1 ネイバーの指定
router eigrp 1 neighbor 192.168.123.2 Serial0/0 neighbor 192.168.123.3 Serial0/0
R2 ネイバーの指定
router eigrp 1 neighbor 192.168.123.1 Serial0/0
R3 ネイバーの指定
router eigrp 1 neighbor 192.168.123.1 Serial0/0
ネイバーを指定すれば、R1-R2間、R1-R3間のEIGRPネイバーを確立することができます。R1でのネイバーの状態は次のようになります。
R1 show ip eigrp neighbors
R1#show ip eigrp neighbors

Step4:ルーティングテーブルの確認
ルーティングテーブルに必要なルート情報が登録されていることを確認します。R1~R3のルーティングテーブルは次のようになります。
R1 show ip route eigrp
R1#show ip route eigrp
D 192.168.25.0/24 [90/2195456] via 192.168.123.2, 00:02:36, Serial0/0

D 192.168.0.6 [90/409600] via 192.168.36.6, 00:16:38, Ethernet1/0
スポークルータのR2のルーティングテーブルには、R3配下のルートが存在しません。同様に、R3のルーティングテーブルにはR2配下のルートが存在しません。
Step5:スプリットホライズンの無効化
スポークルータ間でのルートの送受信ができていなのは、スプリットホライズンによるものです。R1 Serial0/0でスプリットホライズンを無効化します。
R1 スプリットホライズンの無効化
interface Serial0/0 no ip split-horizon eigrp 1
スプリットホライズンを無効化すると、R2とR3のルーティングテーブルに必要なルート情報が登録されるようになったことがわかります。
R2 show ip route eigrp
R2#show ip route eigrp

Step6:ネイバー認証の設定
フレームリレー上でネイバー認証を行います。EIGRPのネイバー認証では、パスワードの設定としてキーチェインを利用します。R1/R2/R3でネイバー認証のための設定コマンドは同じです。
R1/R2/R3 ネイバー認証の設定
key chain EIGRP key 1 key-string cisco ! interface Serial0/0 ip authentication mode eigrp 1 md5 ip authentication key-chain eigrp 1 EIGRP
Step7:ネイバー認証の確認
ネイバー認証の確認のために、次のshowコマンドを実行します。
- show ip eigrp interfaces detail
- show key chain
- show ip eigrp neighbors
R1では、次のような表示です。
R1 ネイバー認証の確認
R1#show ip eigrp interfaces detail serial 0/0

0 192.168.14.4 Et1/0 12 00:44:24 33 200 0 11
Step8:タイマと帯域幅の設定
フレームリレー上でネイバー障害の検出を10秒以内にするために、ホールドタイマを10秒にします。それに合わせてHelloインターバルを3秒にします。また、Serial0/0でEIGRPパケットが利用する帯域幅を25%とします。
なお、EIGRPでは、OSPFとは異なりネイバー間でHelloインターバルとホールドタイマが不一致でも問題ありません。不一致の場合は、最小値が採用されます。ただし、通常は、タイマの変更は関連するすべてのルータで設定します。
R1/R2/R3 タイマと帯域幅の設定
interface Serial0/0 ip bandwidth-percent eigrp 1 25 ip hello-interval eigrp 1 3 ip hold-time eigrp 1 10
Step9:EIGRPスタブの設定
R6へEIGRPクエリーを送信しないようにするために、R6でEIGRPスタブの設定を行います。R6からアドバタイズするEIGRPルートとしては、デフォルトのconnectedとsummaryとします。
R6 EIGRPスタブの設定
router eigrp 1 eigrp stub connected summary
R3でshow ip eigrp neighbors detailコマンドを見ると、R6がスタブでありクエリーを送信しないことが確認できます。
R3 show ip eigrp neighbors detail
R3#show ip eigrp neighbors detail ethernet 1/0

再配送後にEIGRPトポロジテーブルを確認すると、次のように0.0.0.0/0がEIGRPルートとなっていることがわかります。
