&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・R1からR4の&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;172.16.x.x通信についてメトリック差2倍までの経路は&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　ロードバランシングさせる。&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　【補足】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　&lt;/span&gt;EIGRPでは他のルーティングプロトコルと異なり、異なるメトリックでも&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　&lt;/span&gt;ロード&lt;span style=&quot;font-family: inherit;&quot;&gt;バランシングする事が出来ます。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　尚、varianceコマンドにて実現する事が出来ます。&lt;/span&gt;&lt;br /&gt;

　※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。&lt;br /&gt;
　「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、&lt;br /&gt;
　正常時は「０」です。&lt;br /&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・R1からR4の&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;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&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　R2&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;経由で通信させる。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　ただし、デフォルトメトリックの帯域幅に関しては利用しないこととする。&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　【補足】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　&lt;/span&gt;EIGRPでは複合メトリック 「帯域幅 (bandwidth)/遅延 (delay)/信頼性 (reliability)/&lt;br /&gt;
　　　負荷(load)/MTU」を利用します。&lt;br /&gt;
　　　※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、&lt;br /&gt;
　　　 &amp;nbsp; 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。&lt;br /&gt;
　　　&lt;br /&gt;
　　　尚、K値を変更する際はmetric weightsコマンドで変更する必要がございます。&lt;br /&gt;
&lt;br /&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・R1からR4の&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;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&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　R2&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;経由で通信させる。&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　【補足】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　&lt;/span&gt;EIGRPでは複合メトリック 「帯域幅 (bandwidth)/遅延 (delay)/信頼性 (reliability)/&lt;br /&gt;
　　　負荷(load)/MTU」を利用します。&lt;br /&gt;
　　　※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、&lt;br /&gt;
　　　 &amp;nbsp; 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。&lt;br /&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・EIGRPのおける集約設定(ip summary-address eigrp )の挙動を理解する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　※集約設定はR2で実施する事。&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　&lt;span style=&quot;font-family: inherit;&quot;&gt;【補足】&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　EIGRPで集約する方法は大きく2パターンある。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　①自動集約による集約経路の広告&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・ルータコンフィグレーションモードにて設定&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・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。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・&lt;/span&gt;クラスフルでの集約のみサポート&lt;br /&gt;
　　　　・EIGRP内部経路のみ集約可能&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　②集約による集約経路の広告&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・IFモードにて設定&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　・集約プレフィックスを細かく設定可能&lt;/span&gt;&lt;br /&gt;
　　　　・EIGRP内部経路/外部経路共に集約可能&lt;br /&gt;
　　　　・設定方法は以下の2パターンあります。&lt;br /&gt;
　　　　　(1)ip summary-address eigrp [AS番号][ネットワークアドレス][サブネットマスク]&lt;br /&gt;
　　　　　　&amp;lt;例&amp;gt;ip summary-address eigrp 1 172.16.0.0 255.255.240.0&lt;br /&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・EIGRPのおける集約設定(auto summary / no auto summary )の挙動を理解する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;br /&gt;&lt;/span&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　EIGRPで集約する方法は大きく2パターンある。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　①自動集約による集約経路の広告&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・ルータコンフィグレーションモードにて設定&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・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。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・&lt;/span&gt;クラスフルでの集約のみサポート&lt;br /&gt;
　　　　・EIGRP内部経路のみ集約可能&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　②手動集約による集約経路の広告&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・IFモードにて設定&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　・集約プレフィックスを細かく設定可能&lt;/span&gt;&lt;br /&gt;
　　　　・EIGRP内部経路/外部経路共に集約可能&lt;br /&gt;
&lt;br /&gt;

&lt;div style=&quot;font-family: -webkit-standard;&quot;&gt;
&lt;div style=&quot;margin: 0px;&quot;&gt;
　EIGRPネイバーが正常に張れている事を確認する。&lt;br /&gt;
　※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。&lt;br /&gt;
　「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、&lt;br /&gt;
　正常時は「０」です。&lt;br /&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・EIGRPのおける集約設定(ip summary-address eigrp )の挙動を理解する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　※集約設定はR2で実施する事。&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　&lt;span style=&quot;font-family: inherit;&quot;&gt;【補足】&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　EIGRPで集約する方法は大きく2パターンある。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　①自動集約による集約経路の広告&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・ルータコンフィグレーションモードにて設定&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・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。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・&lt;/span&gt;クラスフルでの集約のみサポート&lt;br /&gt;
　　　　・EIGRP内部経路のみ集約可能&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　②集約による集約経路の広告&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・IFモードにて設定&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　・集約プレフィックスを細かく設定可能&lt;/span&gt;&lt;br /&gt;
　　　　・EIGRP内部経路/外部経路共に集約可能&lt;br /&gt;
　　　　・設定方法は以下の2パターンあります。&lt;br /&gt;
　　　　　(1)ip summary-address eigrp [AS番号][ネットワークアドレス][サブネットマスク]&lt;br /&gt;
　　　　　　&amp;lt;例&amp;gt;ip summary-address eigrp 1 172.16.0.0 255.255.240.0&lt;br /&gt;
　　　　　(2)ip summary-address eigrp [AS番号][ネットワークアドレス][プレフィックス]&lt;br /&gt;

&lt;span style=&quot;font-size: large;&quot;&gt;&lt;span style=&quot;font-family: &amp;quot;ｍｓ ｐゴシック&amp;quot;;&quot;&gt;◾️&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-size: large;&quot;&gt;OSPF Timers 5 (throttle las)&lt;/span&gt;&lt;/h2&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・OSPFのthrottle LSAタイマーをを変更する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　①LSA start-interval&lt;/span&gt;を10ミリ秒に変更する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　②LSA hold-interval&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;を3&lt;span style=&quot;font-family: inherit;&quot;&gt;0ミリ秒&lt;/span&gt;に変更する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　③LSA max wait-interval&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;を200ミリ秒に変更する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　※上記タイマー変更がOSPFネイバに影響しないか確認する為に、R1にのみ設定する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　実務で利用する際は、全OSPFネットワークで合わせた方が良いと思う。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　&lt;span style=&quot;font-family: inherit;&quot;&gt;【補足】&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　throttle LSAとはOSPFネイバーからLSAを受信後、他のOSPFルータへLSAを送信する&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　する迄の時間間隔をチューニングする事ができる設定である。&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　OSPFでは不安定なネットワークからのLSAを受信し、そのネットワークが多々&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　フラッディングするLSAを他のOSPFルータへ送信すると、最終的には都度SPF計算が&lt;/span&gt;&lt;br /&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・OSPFのthrottle SPFタイマーをを変更する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　①sfp start-interval&lt;/span&gt;を1秒に変更する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　②sfp hold-interval&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;を3秒に変更する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　③sfp max wait-interval&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;を5秒に変更する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　※上記タイマー変更がOSPFネイバに影響しないか確認する為に、R1にのみ設定する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　実務で利用する際は、全OSPFネットワークで合わせた方が良いと思う。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　&lt;span style=&quot;font-family: inherit;&quot;&gt;【補足】&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　OSPFでは不安定なネットワークからのLSAを受信し、そのネットワークが多々&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　フラッディングして都度SPF計算が実行されるとOSPFネットワークの&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;負荷が増大&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;background-color: white;&quot;&gt;　　その為、SPF の計算はLSAを受信してもすぐに実行されず&lt;/span&gt;&lt;span class=&quot;cCN_CmdName&quot; style=&quot;border: 0px; line-height: inherit; margin: 0px; padding: 0px; vertical-align: baseline;&quot;&gt;timers throttle spf&amp;nbsp;&lt;/span&gt;&lt;span style=&quot;background-color: white;&quot;&gt;コマンドで&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;background-color: white;&quot;&gt;　　設定&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;background-color: white; font-family: inherit;&quot;&gt;した時間間隔に基づいてで実行される。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;background-color: white;&quot;&gt;　　まず、最初のLASを受信したら&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;sfp start-interval後にSPF計算が実行され、その後&lt;/span&gt;&lt;span style=&quot;background-color: white; font-family: inherit;&quot;&gt;計算　&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;background-color: white; font-family: inherit;&quot;&gt;　　を行うたびに、以下のとおりSPF計算タイミングがずれていきます。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;background-color: white; font-family: inherit;&quot;&gt;&lt;br /&gt;&lt;/span&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　実務で利用する際は、全OSPFネットワークで合わせた方が良いと思う。&lt;/span&gt;&lt;br /&gt;

&lt;span style=&quot;background-color: white;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　のLSAを1つのグループに纏めて処理する事により、負荷を軽減しております。&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・OSPFの&lt;span style=&quot;font-family: -webkit-standard;&quot;&gt;retransmitタイマー&lt;/span&gt;及び&lt;span style=&quot;font-family: -webkit-standard;&quot;&gt;transmit-delay&lt;/span&gt;&lt;span style=&quot;font-family: -webkit-standard;&quot;&gt;タイマー&lt;/span&gt;を変更する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　※上記タイマー変更がOSPFネイバに影響しないか確認する為に、R1にのみ設定する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　実務で利用する際は、全OSPFネットワークで合わせた方が良いと思う。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　&lt;span style=&quot;font-family: inherit;&quot;&gt;【補足】&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・&lt;/span&gt;retransmitタイマー&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　&lt;/span&gt;retransmitタイマーとはネイバーを確立しているOSPFルータヘLSAを送信し、その&lt;br /&gt;
　　　ルータからLSAの受信応答がなかった場合に再度LSAを送信するまでの間隔の事。&lt;br /&gt;
　　　※デフォルトでは5秒です。&lt;br /&gt;
&lt;br /&gt;
　　・transmit-delayタイマー&lt;br /&gt;
　　　transmit-delayタイマーとはOSPFルータが遠隔地にある場合、予め転送遅延値を考慮&lt;br /&gt;
　　　する際の時間間隔の事。(OSPFデータベースのLS値をプラスする)&lt;br /&gt;
　　　※デフォルトは1秒です。&lt;br /&gt;
&lt;br /&gt;
&lt;br /&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・OSPFのHelloインターバル及びDeadインターバルの間隔を変更する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;br /&gt;&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　&lt;span style=&quot;font-family: inherit;&quot;&gt;【補足】&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・OSPFは定期的にHelloパケットを隣接ルータへ送出し、OSPFネイバー同士で&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　死活管理を実施している。&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　なお、隣接ルータからHelloパケットを一定期間(Deadインターバル)受信出来ない&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　場合、OSPFネイバー&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;関係を解消する。&lt;/span&gt;&lt;br /&gt;
　　　※Helloインターバル及びDeadインターバルの間隔のデフォルト値は、OSPF　&lt;br /&gt;
　　　　ネットワークタイプにより異なる。&lt;br /&gt;
　　　OSPFネイバーを確立する際、Helloインターバル及びDeadインターバル双方を&lt;br /&gt;
　　　隣接ルータ同士で合わせることが必須です。&lt;br /&gt;
&amp;nbsp;　　　※OSPFネットワークタイプは双方で合わせる必要はない。　　　&lt;br /&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;※&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;マルチキャストが利用できない際は&lt;/span&gt;&lt;span style=&quot;font-family: inherit; line-height: normal;&quot;&gt;hello&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;でのネイバー検出ができない為、&lt;/span&gt;&lt;span style=&quot;font-family: inherit; line-height: normal;&quot;&gt;Neighbor&lt;/span&gt;&lt;br /&gt;
&lt;div style=&quot;line-height: normal;&quot;&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　コマンドで対向&lt;span style=&quot;line-height: normal;&quot;&gt;IP&lt;/span&gt;アドレスを明示的に設定する。&lt;/span&gt;&lt;/div&gt;
&lt;br /&gt;
Helloインターバルを1秒以下にする必要がある場合は、FastHelloという機能がある。&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;FastHelloを有効にすると、&lt;span style=&quot;line-height: normal;&quot;&gt;1&lt;/span&gt;秒間よりも短い間隔で&lt;span style=&quot;line-height: normal;&quot;&gt;hello&lt;/span&gt;パケットを送信する事が出来ます。これを設定すると自動的に&lt;span style=&quot;line-height: normal;&quot;&gt;Dead&lt;/span&gt;インターバルは「&lt;span style=&quot;line-height: normal;&quot;&gt;1&lt;/span&gt;秒」となります。(別途、検証予定)&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;※実務で使う必要がある場合はOSPFルータへ負荷がとてもかかる為、注意が必要です。&lt;/span&gt;&lt;br /&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・以下の構成図のようなOSPF及びEIGRP環境を構築し、双方のルーティングドメイン&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　間で経路情報を再配布する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　その際、ABRにてType7からType5へ変換する時にLSA Type-7にの&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;Forward Address&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　を意図的に0.0.0.0に変更する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　【補足】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　以下のようなOSPFエリア0及びサブエリア(NSSA)で構成されている場合、&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　NSSAに接続されている他ルーティングドメインの経路はNSSA内はLSA Type7で伝搬&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　させます。&lt;/span&gt;※ASBR(R3)にて自身のIPをForward Addressへセットします。&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　その後、ABR(R2)にて&lt;/span&gt;LSA Type7をLSA Type5へ変換いたします。&lt;br /&gt;
　　※その際LSA Type7に含まれているForward Addressはそのまま引き継ぎます。&lt;br /&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・以下の構成図のようなOSPF及びEIGRP環境を構築し、双方のルーティングドメイン&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　間で経路情報を再配布する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　その際、OSPFデータベース(Type5)内のForwarding Addressの挙動を確認する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　【補足】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;　　OSPFでは外部経路への疎通性に関しては、 LSA Type5内の&lt;/span&gt;Forward Addressに&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　「0.0.0.0」がセットされている場合は、Advertising Routerにセットされている&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　IPアドレス宛へ&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;パケットを転送されます。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　しかし、&lt;span style=&quot;color: red;&quot;&gt;LSA Type5内のForward Addressに0.0.0.0以外のIPアドレスがセットされている&lt;/span&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;color: red; font-family: inherit;&quot;&gt;　　際は、Advertising RouterにセットされているIPアドレスではなく&lt;b&gt;Forward Addressに&lt;/b&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;color: red; font-family: inherit;&quot;&gt;&lt;b&gt;　　セットされているIPアドレス宛へパケットを転送&lt;/b&gt;します。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　※その際、Forward Addressは外部経路を広告したルータのIPアドレスが入ります。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　&lt;/span&gt;&lt;br /&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・以下の構成図のようなOSPFマルチエリアを構築し、&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　ASRにて一部の外部エリア経路をフィルタする。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　[フィルタ経路]&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　172.16.3.0/24及び172.16.4.0/24はR1へ経路広告しない。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;br /&gt;&lt;/span&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　【補足】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;スタブエリア/完全スタブエリアはOSPFエリア間フィルタ手法の１つである。&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　OSPF経路をフィルタする方法は以下の３つある。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　①&lt;/span&gt;distribute-listコマンドにてルーティングテーブルにインストールする経路情報を&lt;br /&gt;
　　　　フィルタする。&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　&lt;span style=&quot;color: red;&quot;&gt;②&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;color: red;&quot;&gt;filter-listコマンドにてLSA3の情報をフィルタする。※今回の検証内容です。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　③特殊エリアにてLSAをフィルタする事により、経路フィルタを実装する方法。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;&lt;br /&gt;&lt;/span&gt;

&lt;span style=&quot;font-family: inherit;&quot;&gt;　【課題】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　・以下の構成図のようなOSPFマルチエリアを構築し、スタブエリア/完全スタブエリア&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　の挙動について&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;理解する。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　【補足】&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　NSSA&lt;/span&gt;&lt;span style=&quot;font-family: inherit;&quot;&gt;/完全NSSAはOSPFエリア間フィルタ手法の１つである。&lt;/span&gt;&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　OSPF経路をフィルタする方法は以下の３つある。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　①&lt;/span&gt;distribute-listコマンドにてルーティングテーブルにインストールする経路情報を&lt;br /&gt;
　　　　フィルタする。&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　②&lt;/span&gt;filter-listコマンドにてLSA3の情報をフィルタする。&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　③特殊エリアにてLSAをフィルタする事により、経路フィルタを実装する方法。&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　&amp;lt;特殊エリアの種類&amp;gt;&lt;/span&gt;&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・スタブエリア&lt;/span&gt;&lt;br /&gt;
　　　　　 同一エリア内から経路(LSA 1/LSA 2)は全て受信する。&lt;br /&gt;
　　　　　ただし、他のエリア経路はLSA 3のみ受信し、LSA4/LSA5は受信しない。&lt;br /&gt;
　　　　　※代わりにABRからデフォルトルートを受信する。&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　　　・完全スタブエリア(トータリースタブエリア)&lt;/span&gt;　※今回の検証内容です。&lt;br /&gt;
　　　　　 同一エリア内から経路(LSA 1/LSA 2)は全て受信する。&lt;br /&gt;
　　　　　ただし、他のエリア経路(LSA3~5)は全て受信しない。&lt;br /&gt;
　　　　　※代わりにABRからデフォルトルートを受信する。&lt;br /&gt;
&lt;br /&gt;
&lt;span style=&quot;font-family: inherit;&quot;&gt;　　&lt;span style=&quot;color: red;&quot;&gt;　　・NSSA&lt;/span&gt;&lt;/span&gt;&lt;span style=&quot;color: red;&quot;&gt;　※今回の検証内容です。&lt;/span&gt;&lt;br /&gt;
　　　　　 同一エリア内から経路(LSA 1/LSA 2)は全て受信する。&lt;br /&gt;
　　　　　ただし、他のエリア経路はLSA 3のみ受信し、LSA4/LSA5は受信しない。&lt;br /&gt;
　　　　　※NSSAではABRによるデフォルトルート伝搬はしない。&lt;br /&gt;
　　　　　また、外部経路(他ルーティングドメイン)の経路はASBRにてType5からType7&lt;br /&gt;
　　　　　へ変換し、NSSA内を伝搬させる。&lt;br /&gt;
&lt;br /&gt;
　　　　&lt;span style=&quot;color: red;&quot;&gt;・完全NSSA(トータリーNSSA)　※今回の検証内容です。&lt;/span&gt;&lt;br /&gt;
　　　　　 同一エリア内から経路(LSA 1/LSA 2)は全て受信する。&lt;br /&gt;
　　　　　ただし、他のエリア経路(LSA3~5)は全て受信しない。&lt;br /&gt;
　　　　　※代わりにABRからデフォルトルートを受信する。&lt;br /&gt;
　　　　　また、外部経路(他ルーティングドメイン)の経路はASBRにてType5からType7&lt;br /&gt;
　　　　　へ変換し、NSSA内を伝搬させる。&lt;br /&gt;
