Node C (Called Node) Configuration

The following commands configure two channel groups with three total timeslots on T1 sub-
interface 0/2:0:
XSR(config)#controller t1 0/2/0
XSR(config-controller<T1-0/2:0>)#channel-group 1 timeslots 2
XSR(config-controller<T1-0/2:0>)#channel-group 0 timeslots 1
XSR(config-controller<T1-0/2:0>)#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 28
XSR(config-if<BRI-1/0>)#no shutdown
The following commands add a dialer pool, enable MLPPP, 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 28
XSR(config-if<D1>)#encapsulation ppp
XSR(config-if<D1>)#ip address 10.10.10.3 255.255.255.0
XSR(config-if<D1>)#ppp multilink
The following commands configure Serial sub-interface 2/0:0:
XSR(config)#interface serial 2/0:0
XSR(config-if<S2/0:0>)#no shutdown
XSR(config-if<S2/0:0>)#encapsulation ppp
XSR(config-if<S2/0:0>)#ip address 30.30.30.3 255.255.255.0

Configuration for Ethernet Failover

This example provides DSL backup (PPPoE) on a FastEthernet interface. Dialer interface 57 is
configured as the backup for FastEthernet sub-interface 2.1 - invoking the sub-interface enables
PPPoE. Note that the IP address of the PPPoE caller is negotiated over PPP and the MTU size is
reset to 1492 bytes to avoid Web access problems by PCs attached to the XSR.
XSR(config)#interface fastethernet 2.1
XSR(config-if<F2.1>#backup interface dialer 57
XSR(config-if<F2.1>)#encapsulation ppp
XSR(config-if<F2.1>)#ip address negotiated
XSR(config-if<F2.1>)#ip mtu 1492
XSR(config-if<F2.1>)#no shutdown
