Chapter 1 Configuration of Backup Center

1.1 Backup Center Overview

To enhance network’s reliability, VRP provides perfect backup functions through the use of Backup Center.

zInterfaces that can be backed up are called main interfaces. Every physical interface or sub-interface on a router can serve as a main interface. A logical channel such as X.25 on any interface or a virtual circuit of a frame relay can also serve as a main interface.

zAny physical interface, virtual interface template, or a logical channel on an interface other than the Ethernet interface of a router can serve as the backup interface of aother interface or logical channel.

zA main interface can be provided with multiple backup interfaces; when the main interface gets faulty, backup interfaces can take over the main interface’s work in an order based on their priority.

zInterfaces (such as ISDN BRI and ISDN PRI interfaces) that have multiple physical channels can provide backups to multiple main interfaces by using Dialer Map.

1.2Configuring the Backup Center

1.2.1 Configuration Task List

Follow the steps below to configure VRP backup center.

zEnter the configuration mode of the main interface to be backed up.

zSpecify the backup interface and priority used by the main interface.

zSet the delay time for the switchover between main and backup interfaces.

zSet state-judging conditions when the main interface is a logical channel.

zSet the state-judging conditions when the backup interface is a logical channel.

zConfigure routes for main and backup interfaces.

1.2.2Entering the Configuration Mode of the Main Interface to be Backed Up

On a Quidway router, not only every physical interface or sub-interfaces of the router, but every virtual circuit of X.25 or frame relay can work as a main interface. If the main interface is a physical interface or sub-interface, please use the following commands in global configuration mode to enter the configuration mode of the interface.

Enter the configuration mode of the main interface

interface interface-type interface-number

Here, interface-type specifies the interface type of the physical interface or sub- interface, interface-number specifies the interface number of the physical interface or sub-interface. Combined, they specify a physical interface or sub-interface.
