In diesem Dokument wird erläutert, wie Sie Backup Bridging mit ISDN konfigurieren. Diese Konfiguration verwendet die Methode der Sicherungsschnittstelle, um zu erkennen, dass die primäre Verbindung ausgefallen ist. Weitere Informationen zu Backups finden Sie unter Konfigurieren und Beheben von DDR-Backups.
In überbrückten WAN-Umgebungen ist die einzige verfügbare DDR-Backup-Lösung (Dial-on-Demand Routing) die Verwendung von ISDN, da Bridging over Async nicht unterstützt wird.
Beachten Sie, dass das Bridging auf einer ISDN-Verbindung dazu tendiert, die Verbindung für sehr lange, wenn nicht gar für lange Zeit aktiv zu halten. Wenn die Telefongesellschaft ISDN basierend auf der Verbindungszeit berechnet und die nachverfolgte serielle Verbindung für sehr lange Zeit ausfällt, kann dies zu einer sehr großen Rechnung führen.
Hinweis: Diese Konfiguration gilt für einen Standort und einen B-Kanal. Für mehr als einen B-Kanal müssen Sie Dialer-Profile verwenden. (Weitere Informationen finden Sie unter Konfigurieren der Dialer-Profile für die Bridge mithilfe der ISDN-Konfiguration.)
Informationen zur Bridging-Konfiguration in einer Nicht-Backup-Umgebung finden Sie unter Bridging Across ISDN.
Bevor Sie diese Konfiguration versuchen, stellen Sie sicher, dass Sie die folgenden Anforderungen erfüllen:
Grundkenntnisse über ISDN
Die Informationen in diesem Dokument basieren auf den folgenden Software- und Hardwareversionen:
Cisco Router der Serie 2500 mit einer seriellen WAN-Schnittstelle und einer BRI-Schnittstelle.
Cisco IOS® Softwareversion 12.2(7b).
Hinweis: Diese Konfiguration kann mit jedem Router verwendet werden, der über eine (serielle) WAN-Verbindung und einen BRI-Port verfügt.
Die Informationen in diesem Dokument wurden von den Geräten in einer bestimmten Laborumgebung erstellt. Alle in diesem Dokument verwendeten Geräte haben mit einer leeren (Standard-)Konfiguration begonnen. Wenn Ihr Netzwerk in Betrieb ist, stellen Sie sicher, dass Sie die potenziellen Auswirkungen eines Befehls verstehen.
Diese Konfiguration kann mit zwei beliebigen Routern verwendet werden, auf denen die Cisco IOS Software ausgeführt wird und die jeweils über mindestens eine serielle WAN-Schnittstelle und eine BRI-Schnittstelle verfügen.
Weitere Informationen zu Dokumentkonventionen finden Sie unter Cisco Technical Tips Conventions.
In diesem Abschnitt erhalten Sie Informationen zum Konfigurieren der in diesem Dokument beschriebenen Funktionen.
Hinweis: Um weitere Informationen zu den in diesem Dokument verwendeten Befehlen zu erhalten, verwenden Sie das Command Lookup Tool (nur registrierte Kunden).
