Ja, sobald IP-Pakete ins Internet gelangen, sind die Navigationsinformationen bereits unterwegs und warten auf deren Ankunft.

Ich werde diese Frage nicht sofort beantworten, sondern sie anhand des elektronischen Navigationssystems analysieren. Wenn Sie Zielinformationen eingeben, berechnet das Navigationssystem mithilfe seiner eigenen Kartendatenbank die k\u00fcrzeste Route. Diese Kartendatenbank ist im Navigationssystem vorinstalliert und sollte regelm\u00e4\u00dfig aktualisiert werden, da sich das Stra\u00dfennetz weltweit rasant weiterentwickelt. Andernfalls k\u00f6nnten Sie auf falsche F\u00e4hrten geraten und im Meer landen.<\/p><p>Wenn jeder Router \u00fcber \u00e4hnliche Verbindungsinformationen wie eine Kartendatenbank verf\u00fcgt, kann er den k\u00fcrzesten Pfad zur Navigation nutzen. Ein Protokoll zum Austausch von Verbindungsinformationen zwischen den Routern wird als Routing-Protokoll bezeichnet. Dieser Artikel soll Ihnen das Routing-Protokoll n\u00e4herbringen. Sie sollten nun wissen, was Routing ist, aber was genau ist das Protokoll? Das Protokoll legt fest, wie die Verbindungsinformationen ausgedr\u00fcckt werden, wie hoch die Kosten f\u00fcr die Durchquerung dieser Verbindung sind und welche Router sich an beiden Enden der Verbindung befinden. Mithilfe dieser Informationen k\u00f6nnen die Router dynamisch eine Karte (ein topologisches Diagramm) des gesamten Netzwerks erstellen. F\u00fcr jedes Ziel wird dynamisch ein Routing-Eintrag gem\u00e4\u00df dem Algorithmus f\u00fcr den k\u00fcrzesten Pfad generiert und in eine Tabelle, die sogenannte Routing-Tabelle, eingetragen.<\/p><p>Wer mit Routing-Protokollen vertraut ist, kann leicht vermuten, dass es sich bei den von mir erw\u00e4hnten Routing-Protokollen um OSPF und IS-IS handelt. Sie sind sich sehr \u00e4hnlich. Beide sind Link-State-Protokolle. Sie erfassen zun\u00e4chst Verbindungsinformationen zwischen Routern, wie Kosten, verbundene Knoten an beiden Enden und Verbindungstypen, und f\u00fchren dann einen Algorithmus aus, der dem k\u00fcrzesten Pfad \u00e4hnelt, um die Informationen f\u00fcr die Routing-Tabelle zu generieren.<\/p><p><strong>Welches Routing-Protokoll soll gew\u00e4hlt werden?<\/strong><\/p><p>So \u00e4hnlich, warum?! Es handelt sich um zwei parallel von zwei verschiedenen Organisationen entwickelte Abkommen. Niemand hat einen absoluten Vorteil, also soll der Markt sie testen! IS-IS hat hinsichtlich Protokollentwicklung und Skalierbarkeit mehr Vorteile, und OSPF k\u00f6nnte an Bedeutung verlieren.<\/p><p>Heute diskutieren wir nicht dar\u00fcber, wer gewinnen wird, sondern widmen uns der ersten Frage: Wenn OSPF und IS-IS auf demselben Router laufen und beide Routingtabellen f\u00fcr dasselbe Ziel (gleiche Netzwerkadresse und gleiche Netzwerkmaske) generieren, welche wird dann verwendet? Dies ist eine schwierige Priorit\u00e4tsentscheidung. Jeder Hersteller hat seine eigene Vorgehensweise. Cisco verwendet eine etwas ungew\u00f6hnliche Bezeichnung: Administration Distance (AD), um die Priorit\u00e4ten zu unterscheiden. Priorit\u00e4t 0 ist die h\u00f6chste, Priorit\u00e4t 255 die niedrigste. OSPF verwendet standardm\u00e4\u00dfig Priorit\u00e4tsbit 110, IS-IS hingegen Priorit\u00e4t 115. Offensichtlich haben die Routinginformationen von OSPF Vorrang. Ein Beispiel zur Veranschaulichung:<\/p><p>OSPF-Route: 10.1.1.0\/24 n\u00e4chster Hop aaaa AD 110<\/p><p>IS-IS-Route: 10.1.1.0\/24 n\u00e4chster Hop bbbb AD 115<\/p><p>Folgendes wird dann in die Routingtabelle eingetragen:<\/p><p><strong>OSPF-Route: 10.1.1.0\/24 n\u00e4chster Hop aaaa AD 110<\/strong><\/p><p>Lassen Sie sich nicht t\u00e4uschen: OSPF hat keine hohe und IS-IS keine niedrige AD-Priorit\u00e4t. Wenn OSPF und IS-IS gleichzeitig laufen, werden nicht alle Routing-Eintr\u00e4ge von IS-IS in die Routing-Tabelle aufgenommen. Das ist falsch! Nur gleichwertige Routing-Eintr\u00e4ge k\u00f6nnen anhand der AD-Priorit\u00e4t entscheiden, ob sie in der Tabelle verbleiben oder nicht. Sind die Eintr\u00e4ge nicht gleichwertig, wird die AD-Priorit\u00e4t gar nicht ber\u00fccksichtigt.<\/p><p>Selbstverst\u00e4ndlich gibt es weitere Protokolle, die um den Eintrag in die Routingtabelle konkurrieren k\u00f6nnen: RIP(120), EIGRP(90), BGP(20,200) sowie die direkt verbundene Route (0) und die statische Route (1), mit ihrer AD-Priorit\u00e4t und dem externen BGP in Klammern.<\/p><p>20, und intern BGP ist 200. Aktuell ist die AD-Priorit\u00e4t g\u00e4ngiger Routing-Protokolle:<\/p><p>Direkte Route &gt; statische Route &gt; EBGP &gt; EIGRP &gt; OSPF &gt; ISIS &gt; RIP &gt; IBGP<\/p><p><strong>Welcher ist der beste n\u00e4chste Schritt?<\/strong><\/p><p>Nachdem wir die Routingtabelle besprochen haben, wollen wir uns nun damit befassen, wie IP-Pakete den Router erreichen, wie man die Routingtabelle findet und die Navigation der IP-Pakete durchf\u00fchrt. Wie findet man den n\u00e4chsten Hop mit h\u00f6chster Effizienz und Genauigkeit?<br \/>Wenn die Routingtabelle die folgenden f\u00fcnf Eintr\u00e4ge enth\u00e4lt und die Zieladresse des IP-Pakets 10.1.1.1 lautet, welchen Eintrag w\u00e4hlt die Routingtabelle aus?
