routergodsトポロジの.netファイル改造
INEのWorkbookをGNS3でお勉強するために、ありがたく使わせてもらってるトポロジ。 http://www.routergods.com/links/ine-gns3-configs/
複数の環境で使ってるんだけど、WindowsXP 4GBメモリ搭載PCだと実行するトポロジによっては全ノード起動前にエラーで落ちるんだよね。確認してみたら2プロセス分割なので、1プロセスの使用メモリが1GB超えるパターンがあるせいみたい。
なので、同じconfigファイルを使用する.netファイルを作成してみました。これだと1プロセスあたり600MB程度になるので落ちることがなくなった！（現在の最新版 0.8.5 で作ってます）
変更点としては
- 未使用のWICの除去とWIC-2Tの活用
- SW1〜SW4のシンボルをEtherSwitch Routerに変更
- GNS3のデフォルトに従って1プロセス4ノードでプロセス分割
- BB1〜BB3はメモリ256MB固定割り当て
かな。
使う場合は
- ##IOS_PATH## をIOSイメージの絶対パスに書き換え
- ##IDLEPC## をIOSイメージに対応したidlepc値に書き換え
- ##RAM_SIZE## を各ルータ、スイッチのメモリ容量に書き換え
- ##WORKING## をワークパスに書き換え（RAMディスクとかにするといいよ！）
- ##CFG_PATH## をもとのRouterGodsさんの提供するコンフィグ格納フォルダに変更
してもらうとよいです。
