10-32 Configuring Dialer Services
XSR(config-if<D1>)#dialer pool 1
XSR(config-if<D1>)#no shutdown
The following commands add a dialer pool member and specify the primary-ni switch on XSR-
Toronto’s T1 interface 2/3:
XSR(config)#controller t1 2/3
XSR(config-controller<T1-1/1>)#switch-type primary-ni
XSR(config-controller<T1-1/1>)#dialer pool-member 1
XSR(config-controller<T1-1/1>)#no shutdown
Dial-out Router Example
The following commands add a dialer pool and dialer group and specify the call destination -
XSR-Toronto on XSR-Andover’s Dialer interface 1.
XSR(config)#interface dialer 1
XSR(config-if<D1>)#encapsulation ppp
XSR(config-if<D1>)#ip address 172.22.85.2
XSR(config-if<D1>)#ppp multilink
XSR(config-if<D1>)#multilink min-links 2
+ Brings up a minimum of 2 links on XSR-Andover’s Dialer interface 1
XSR(config-if<D1>)#dialer pool 1
XSR(config-if<D1>)#no shutdown
XSR(config-if<D1>)#dialer string 47410
XSR(config-if<D1>)#dialer-group 1
These 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
The following command defines interesting packets for the dial out trigger by configuring ACL 101
to pass all Type 8 source and destination ICMP traffic up to 20 idle seconds:
XSR(config)#access-list 101 permit icmp any any 8
MLPPP Point-to-Multipoint Configurations
The following MLPPP point-to-multipoint topology can be used for BoD applications, as
illustrated by
Figure 10-15 . This example creates multiple switched lines linking users on XSR-
Toronto’s network with those on three remote networks.
