設定条件
Part1:OSPFの基本設定
- 図 ルーティングプロトコルの構成のように、OSPFおよびRIPv2の設定を行います。OSPFルータのルータIDは、YY.YY.YY.YY(YY:ルータ番号)とします。また、将来的なギガビットイーサネット導入に対応できるように設定します。
- 不要なインタフェースにはルーティングプロトコルのパケットを送信しないようにします。
- R42では、RIPv2のルートをOSPFへ再配送します。また、R42はR43へRIPv2でデフォルトルートをアドバタイズします。
- 10.0.0.0/24上では、R11がDR、R12がBDRとなるようにします。また、MD5によるネイバー認証を行い、ネイバーの障害検出を4秒以内にできるようにします。
Part2デフォルトルートの生成 -> このページで設定
- R13、R14でインターネットへルーティングするためのデフォルトルートをスタティックで設定します。
- R13、R14でOSPFドメインにデフォルトルートを生成します。インターネットへのルーティングはR13を優先します。
Part3:スタブエリアの設定
- エリア2、エリア4にはLSAタイプ5をアドバタイズしないように設定します。エリア4にはインターネットへの接続性を確保するために、デフォルトルートをアドバタイズできるようにします。
- エリア3のLSDBのサイズが最も小さくなるように設定します。
Part4:ルート集約
- エリア1、エリア2、エリア3、エリア4のネットワークアドレスを集約してバックボーンエリアにアドバタイズします。
- RIPv2ドメインのルートを集約してOSPFドメインへアドバタイズします。
初期設定
「演習:実践的なOSPFルーティング Part1」完了時点から開始します。

設定と確認 Part2:デフォルトルートの生成
Step1:デフォルトルートの設定
R13、R14でインターネットへパケットをルーティングするためにISPをネクストホップとするデフォルトルートをスタティックで設定します。
R13 デフォルトルートの設定
ip route 0.0.0.0 0.0.0.0 100.1.0.2
R14 デフォルトルートの設定
ip route 0.0.0.0 0.0.0.0 100.1.0.6
Step2:OSPFでのデフォルトルート生成
R13、R14でOSPFドメインにデフォルトルートをアドバタイズします。R13を優先するため、R13で生成するデフォルトルートのメトリックタイプを1とします。
R13 OSPFデフォルトルートの設定
router ospf 1 default-information originate metric-type 1
R14 OSPFデフォルトルートの設定
router ospf 1 default-information originate
Step3:OSPFでのデフォルトルート生成の確認
R13、R14で生成したデフォルトルートを確認するために、以下のshowコマンドを実行します。
- show ip ospf database external 0.0.0.0
- show ip route 0.0.0.0
R11では、次のようになります。
R11 OSPFデフォルトルートの確認

R13はメトリックタイプ1の外部ルートとしてデフォルトルートを生成し、OSPFドメインにアドバタイズしていることがわかります。また、R14はメトリックタイプ2の外部ルートとしてデフォルトルートを生成し、OSPFドメインにアドバタイズしています。
そして、メトリックタイプ1の外部ルートとメトリックタイプ2の外部ルートでは、メトリックの値によらずメトリックタイプ1の外部ルートが優先されます。そのため、OSPFドメインのルータはR13が生成したデフォルトルートをルーティングテーブルに登録します。
