Dialer Profiles

Dialer Profiles allow a great deal of flexibility in the configuration of DDR circuits, allowing one physical interface to be used for multiple functions.

Dialer Profiles Example

R4(config)# interface bri 0/0 R4(config-if)# no ip address R4(config-if)# encapsulation ppp R4(config-if)# dialer pool-member 1

R4(config-if)# exit

R4(config)# dialer-list 1 protocol ip permit R4(config)# interface dialer 1

R4(config-if)# ip address 172.16.14.1 255.255.255.252 R4(config-if)# encapsulation ppp R4(config-if)# dialer string 8140010 R4(config-if)# dialer remote-name R1

R4(config-if)# dialer pool 1 R4(config-if)# dialer-group 1

R4(config-if)# exit

Dialer interfaces are tied to physical interfaces through

the use of the dialer pool and dialer pool-member

commands

Shown here is a configuration that will be examined over the following pages. In this example dialer interface 1 will be used to backup serial 0/0 and dialer interface 2 will be used to transfer e-mail to the Central Office.

(config)# interface bri 0/0 (config-if)# no ip address (config-if)# encapsulation ppp (config-if)# dialer pool-member 1 (config-if)# exit

(config)# dialer-list 1 protocol ip permit (config)# interface dialer 1

(config-if)# ip address 172.16.14.1 255.255.255.252 (config-if)# encapsulation ppp (config-if)# dialer string 8140010 (config-if)# dialer remote-name R1 (config-if)# dialer pool 1 (config-if)# dialer-group 1 (config-if)# exit

(config)# dialer-list 2 protocol ip list 102 (config)# access-list 102 permit tcp any any eq smtp

R4(config)# interface dialer 2

R4(config-if)# ip address 172.16.30.1 255.255.255.252

R4(config-if)# encapsulation ppp

R4(config-if)# dialer string 9650001

R4(config-if)# dialer remote-name CentralOffice

R4(config-if)# dialer pool 1

R4(config-if)# dialer-group 2

R4(config-if)# exit

R4(config)# interface serial 0/0

R4(config-if)# backup interface dialer 1

0 0
