Dial-out Router Example

The following commands add a dialer pool and dialer group, and specify three MLPPP call destinations - XSR-Andover,XSR-Bostonand XSR-Buffalo- on XSR-Toronto’sDialer interface 1. Spoofing also is enabled by the dialer map command.

XSR(config)#interface dialer 1 multi-point

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

XSR(config-if<D1>)#ip address 172.22.85.1

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

XSR(config-if<D1>)#dialer pool 1

XSR(config-if<D1>)#dialer map ip 172.22.85.2 47410

XSR(config-if<D1>)#dialer map ip 172.22.85.3 425688

XSR(config-if<D1>)#dialer map ip 172.22.85.4 987762

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

XSR(config-if<D1>)#dialer-group 1

The following commands add a pool member and configure the primary-ni switch on T1 interface 2/3:

XSR(config)#controller t1 2/3

XSR(config-controller<T1-2/3>)#switch-type primary-ni

XSR(config-controller<T1-2/3>)#dialer pool-member 1

XSR(config-controller<T1-2/3>)#no shutdown

The following command maps ACL 101 to dialer group 1:

XSR(config)#dialer-list 1 protocol ip list 101
