10-28 Configuring Dialer Services
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 pap sent-username XSR-andover password secret 0 dolly
XSR(config-if<D1>)#dialer pool 1
XSR(config-if<D1>)#dialer string 47410
XSR(config-if<D1>)#dialer-group 1
+ Defines interesting packets to trigger dial out
XSR(config-if<D1>)#dialer idle-timeout 20
+ Terminates call to Toronto if the line is idle for 20 seconds
XSR(config-if<D1>)#no shutdown
The following commands add a dial pool member and set the Central Office switch type on BRI
interface 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 1
XSR(config-if<BRI-1/0>)#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 access
list 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
PPP Point-to-Multipoint Configurations
