はじめに

　こんにちは。ネットワークエンジニアの「だいまる」です。

今回は、前回投稿したSR-MPLS TEのExplicit Pathの続きとなるDynamic Pathについて投稿していきたいと思います。

記事一覧（SR-MPLSシリーズ）

SR-MPLS TE Dynamic pathをCMLを使って実装してみた結果

構成図

　今回の実装で用いた構成は、前回同様の構成となります。
　TReXはトラフィックジェネレータを指し、Router1・Router6のルータはIOSとなっております。
　また、Router2〜Router5はIOS-XRとなっており、この4台でSR-MPLSを設定し、TEを実現します。

Dynamic Pathの設定

　Dynamic Pathの設定は、主に2つあります。1つ目はIGPを利用する場合、2つ目がTEメトリックを利用する場合です。
IGPメトリックを利用する場合は、OSPFやIS-ISなどで設定したメトリックを利用するので、policy配下に以下設定を投入することで完了します。

segment-routing
 traffic-eng
  policy <ポリシー名>
   candidate-paths
    preference <pref値>
     dynamic
      metric type igp

　そして、TEメトリックを利用する場合は、メトリックの設定を行い、「metric type igp」の部分を「metric type te」にすることで設定したメトリックを読み取り、トラフィック制御をしてくれます。

segment-routing
 traffic-eng
  interface <IF名>
   metric <metric値>
  policy <ポリシー名>
   candidate-paths
    preference <pref値>
     dynamic
      metric type te

　その上で、今回、実施した内容はOSPFメトリックで流れているトラフィック（Router2→Router4）をTEメトリックを図の通りに設定し、Router2→Router3→Router5→Router4の順で流れるように制御する。

　まず、事前状態の確認となります。
以下のログからわかるように適用されているPolicyは１つもありません（up/downのポリシーが0のため）。また、ルーティングテーブルを確認してもわかるように「10.0.1.4（ルータ4）」向けはSR-TEが適用されておらず、OSPFメトリックにより計算されています。（TI-LFA有効）

　そして、各ルータでTEメトリックの設定を行った後、Router2で以下設定を投入し「10.0.1.4（ルータ4宛）」宛の経路はTEメトリックで計算するように適用しました。

RP/0/RP0/CPU0:Router2(config)#segment-routing traffic-eng 
RP/0/RP0/CPU0:Router2(config-sr-te)#policy POLICY_TEST 
RP/0/RP0/CPU0:Router2(config-sr-te-policy)#candidate-paths

RP/0/RP0/CPU0:Router2(config-sr-te-pp-info)#commit
RP/0/RP0/CPU0:Router2(config-sr-te-pp-info)#end

　上記設定を投入後の状態を確認していくと、「srte_c_10_ep_10.0.1.4」が適用されており、TEメトリックが「active」かつ「valid」になっていることがわかります。また、IGPメトリックはpreference 10で設定しているため、「invalid」になっており、採用されていないことがわかります。
　また、先ほどはpolicyのup/downが全て0だったのに、数字が変化していることからPolicyが適用されていることが確実となります。
　そして、ルーティングテーブルもProtect/BackupとなっていたものがPolicy名になっています。

　上記の結果より、想定通りの経路制御ができていることがわかりました。では、Explicit Pathの時と同じく障害時の動作確認を行っていきましょう。

障害試験（リンク障害）

　リンク障害は、Router2ーRouter3のリンクを切断します。今回、CML GUIからリンクを切断することができることがわかったので、その機能を利用しました。
　結果としては、IGPであるOSPFやIS-ISと同じように経路の再計算が実施され、切り替わりましたが！！
TI-LFAが適用されているはずなのになぜか8秒ぐらい切り替えに時間がかかっているので、原因確認中です。。。

　まずは、事前状態のログを貼り付けていきます。Policyの状態を確認すると、Router3→Router5→Router4経由の経路が最適になっていることがわかります。

最後に

　実装してみて結構文字数が多くなるかと思っていたのですが、意外とすんなり問題なく通ってしまったので少し短い記事となってしまいました。
　次回は、SR-MPLSについての概要編を投稿していき、インプット・アウトプットを繰り返すうちにやってみたいと思ったことがあれば、そこをシリーズの続きとして投稿していこうかと思います。
