１班実験結果
1. 午前の部
1.1 調べた内容とその結果
○切れたときの挙動
R1(a)
|\
| HUB
| \
R2----R3
(H) (B)
・R1とHUBの間を切ってR3から見たときにルートが切り替わるまで3秒。
・つなげて元に戻るまで2秒。
→確認は、pingで行った。
pingを出すのはpriorityが一番高くて、受けるのは低い
→ただし表示されるのは遅いか。
○clear clns と claer isisの違い
1.2 わかったこと
○clear clns と claer isisの違い
・違いはそのままでclns route と isis routeがクリアされた。
・ちなみに、netの設定だけでは自分しか見えない（NSAPは流れない)
(以上 池尻さんの手記より転記)
経路情報の更新タイミング ROUTER Ａにて 確認
H-V 間切断接続の時間 約６秒(切断)〜７秒(接続)で経路伝搬
M-L 約７秒(切断)〜１８秒(接続)で経路伝搬
1.3 今後調べて見たいこと
TARP 関連をまだしてない点があるため 再度挑戦
BGPの経路をくべる点を再度挑戦
実際の運営では どのように注意するか
2. L1での意見＆感想
とくに問題なく接続できた さらに 経路情報のトラフィック等も調べたかった
3. L2での意見＆感想
いまだ 課題として残っており 再度挑戦が必要 L2-L1の TARPの 環境もしないと
実際につかえないので 早急にしてみたい。
＃デフォルトをくべる点がいまだに 気になっている
4. 全体としての反省点
小生のスキルがないのかもしれないが時間が足りませんでしたね。
(＃寝れる場所完備のとこで やらないと １日では 終らないかな。)
あと LOGを 添付します
午前 L１ GROUP１のみ
午前〜午後 L１ 全体接続
午後L２ 接続

経路情報の更新タイミング ROUTER Ａにて 確認
H-V 間切断接続の時間 約６秒(切断)〜７秒(接続)で経路伝搬
M-L 約７秒(切断)〜１８秒(接続)で経路伝搬
Router Bでの経路情報の更新タイミングのデータです。
Router Bにて
○H-V間の shutdown 6秒
no shutdown 7秒
○M-L間の shutdown 6秒
no shutdown 6秒
