Configuring a Dialed Backup Line

Configuring the Interface as the Backup Dialer Interface

1.Enter interface serial card/port to specify the interface to back up.

2.Enter ip address ip-address mask to specify the IP address and subnet mask of the interface.

3.Enter backup interface dialer number as the backup interface.

4.Enter backup delay enable-delaydisable-delayto set the interval between the physical interface going down and the backup being enabled, and between the physical interface coming back up and the backup being disabled.

5.Enter backup time-rangestart-timeend-timeto set the time of day the backup interface should be enabled and disabled.

6.Enable the interface by entering the no shutdown command.

The CLI commands shown below configure the example shown in Figure 8-6on page 8-10.

Configure interface dialer 0 to use dial pool 5:

XSR(config)#interface dialer 0

XSR(config-if<D1>)#encapsulation ppp

XSR(config-if<D1>)#dialer pool 5

XSR(config-if<D1>)#no shutdown

Configure interface dialer 1 to use dial pool 5:

XSR(config)#interface dialer 1

XSR(config-if<D1>)#encapsulation ppp

XSR(config-if<D1>)#ppp authentication chap pap

XSR(config-if<D1>)#dialer pool 5

XSR(config-if<D1>)#no shutdown

Configure serial port(s) for dial purposes and assign to dial pool 5:

XSR(config)#interface serial 1/2

XSR(config-if<S1/2>)#encapsulation ppp

XSR(config-if<S1/2>)#media-type v35

XSR(config-if<S1/2>)#dialer pool-member 5

XSR(config-if<S1/2>)#no shutdown

Configure the primary serial port 1/0 to use dialer 1 as its backup interface:

XSR(config)#interface serial 1/0

XSR(config-if<S1/0>)#ip address 100.100.10.1 255.255.255.0

XSR(config-if<S1/0>)#encapsulation ppp

XSR(config-if<S1/0>)#backup interface dialer0

XSR(config-if<S1/0>)#no shutdown

Configure the primary serial port 1/1 to use dialer 2 as its backup interface:

XSR(config)#interface serial 1/1

XSR(config-if<S1/1>)#backup interface dialer 1

XSR(config-if<S1/1>)#encapsulation ppp

XSR(config-if<S1/1>)#no shutdown
