Backup Configuration

Backup Using ISDN

This example configures ISDN NIM cards (either BRI or T1/E1 configured for PRI) to be used for backing-up other interfaces, as shown in Figure 10-17.

Node A (Backed-up Node) Configuration

The following commands set internal clocking and configure two channel groups with three total timeslots on T1 sub-interface 1/2:0:

XSR(config)#controller t1 1/2/0

XSR(config-controller<T1-1/2:0>)#clock source internal

XSR(config-controller<T1-1/2:0>)#channel-group 1 timeslots 2

XSR(config-controller<T1-1/2:0>)#channel-group 0 timeslots 1

XSR(config-controller<T1-1/2:0>)#no shutdown

The following commands add a dialer pool member and set the Central Office switch type on BRI port 1/0:

XSR(config)#interface bri 1/0

XSR(config-if<BRI-1/0>)#isdn switch-type basic-net3

XSR(config-if<BRI-1/0>)#dialer pool-member 22

XSR(config-if<BRI-1/0>)#no shutdown

The following commands add a dialer pool, set Node C’s dialer number to call, specify a clear text password sent to the peer for PAP authentication, and map BRI interface 1/0 to Dialer interface 1.

XSR(config)#interface dialer 1

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

XSR(config-if<D1>)#dialer pool 22

XSR(config-if<D1>)#dialer string 2500

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

XSR(config-if<D1>)#ip address 10.10.10.1 255.255.255.0

XSR(config-if<D1>)#ppp pap sent-username toronto password ab

The following commands add a dialer pool, set Node C’s dialer number to call, and map BRI interface 1/0 to Dialer interface 2:

XSR(config)#interface dialer 2

XSR(config-if<D2>)#no shutdown
