EIGRP メトリック(遅延)

◾️ EIGRP メトリック(遅延)

　【課題】
　　・R1からR4の172.16.x.x通信についてデフォルトメトリック(遅延)を変更して
　　　R2経由で通信させる。

　【補足】
　　　EIGRPでは複合メトリック「帯域幅 (bandwidth)/遅延 (delay)/信頼性 (reliability)/
　　　負荷(load)/MTU」を利用します。
　　　※EIGRPでは上記メトリックの内、どのメトリックを利用するかに関しては、
　　　 K値の値に基づいて確定します。デフォルトでは帯域幅、遅延のみを利用します。

①検証環境　事前設定確認

(1)EIGRPネイバー確認

　EIGRPネイバーが正常に張れている事を確認する。
　※EIGRPネイバーの正常性確認時に確認するポイントは「Q Cnt」です。
　「Q Cnt」は送信キューに溜まっているEIGRPパケット数がカウントされており、
　正常時は「０」です。

②設定変更(Delay値変更)

(1)R1にてR2向けインターフェースのDelay値変更し172.16.x.x宛をR2経由にする。
<現在の設定値>

R1#show interface e0/0 | include DLY

MTU 1500 bytes, BW 10000 Kbit/sec, DLY 1000 usec,

※上記はDLY 1000usecと表示されておりますが、「μ」が表示出来ない為「u」と表示されている。尚、EIGRPでは10マイクロ秒あたりの遅延値を利用する為、現在の遅延値は1000÷10=100μsecである。
以下のコマンドにより遅延値を10へ現象させる。

R1(config)#int e0/0

R1(config-if)#delay 10

(2)R1 インターフェース確認

R1#show interfaces e0/0 | inc DLY

EIGRP 自動集約設定(auto summary / no auto summary )

◾️EIGRP 自動集約設定(auto summary / no auto summary )

　【課題】
　　・EIGRPのおける集約設定(auto summary / no auto summary )の挙動を理解する。

　【補足】
　　　EIGRPで集約する方法は大きく2パターンある。
　　　①自動集約による集約経路の広告
　　　　・ルータコンフィグレーションモードにて設定
　　　　・クラスフルネットワークの境界ルータにて設定する必要があり。
　　　　・クラスフルでの集約のみサポート
　　　　・EIGRP内部経路のみ集約可能
　　　②手動集約による集約経路の広告
　　　　・IFモードにて設定
　　　　・集約プレフィックスを細かく設定可能
　　　　・EIGRP内部経路/外部経路共に集約可能

(1)R2にてauto-summaryを設定する。
※ネイバーが一度切れます。

R2(config)#router eigrp 1

R2(config-router)#no auto-summary

(2)R1にてルーティング確認をする。
　※自動集約はクラスフルネットワークの境界ルータ(本検証環境でいうとR3)で実施する必要がある為、R2にauto-summaryを設定しても集約されていない事を確認する。
