Chapter 6 Configuring Backup Data Lines and Remote Management

Configuring Cellular Dial-on-Demand Routing Backup

DETAILED STEPS

 

 

Command or Action

 

Purpose

 

 

 

 

 

 

 

 

Step 1

configure terminal

 

Enters global configuration mode.

 

 

Example:

 

 

 

 

 

 

Router# configure terminal

 

 

 

 

 

 

 

 

 

 

 

Step 2

interface type number

 

Specifies the interface.

 

 

Example:

 

 

 

 

 

 

Router (config)# interface 0

 

 

 

 

 

 

 

 

 

 

 

Step 3

dialer watch-group

 

Enables dialer watch on the backup interface.

 

 

group-number

 

 

 

 

 

 

Example:

 

 

 

 

 

 

Router(config-if)# dialer watch-group 2

 

 

 

 

 

 

 

 

 

 

Step 4

dialer watch-listgroup-number ip ip-address

Defines a list of all IP addresses to be watched.

 

 

address-mask

 

 

 

 

 

 

Example:

 

 

 

 

 

 

Router(config-if)# dialer watch-list 2 ip 10.4.0.254

 

 

 

 

 

255.255.0.0

 

 

 

 

 

 

 

 

 

 

Step 5

dialer-list<dialer-group> protocol <protocol-name>

Creates a dialer list for traffic of interest and permits

 

 

{permit deny list <access-list-number>

access to an entire protocol.

 

 

access-group}

 

 

 

 

 

 

Example:

 

 

 

 

 

 

Router(config)# dialer-list 2 protocol ip permit

 

 

 

 

 

 

 

 

 

Step 6

ip access-list <access list number> permit <ip

Defines traffic of interest.

 

 

source address>

 

Do not use the access list permit all command to

 

 

 

 

 

 

 

Example:

 

avoid sending traffic to the IP network. This may

 

 

 

result in call termination.

 

 

Router(config)# access list 2 permit 10.4.0.0

 

 

 

 

 

 

 

 

 

 

Step 7

interface cellular 0

 

Specifies the cellular interface.

 

 

Example:

 

 

 

 

 

 

Router (config)# interface cellular 0

 

 

 

 

 

 

 

 

 

 

 

Step 8

dialer string <string>

 

CDMA only. Specifies the dialer script (defined

 

 

 

 

 

using the chat script command).

 

 

or

 

 

 

 

 

 

dialer group <dialer group number>

 

GSM only. Maps a dialer list to the dialer interface.

 

 

Example:

 

 

 

 

 

 

Router (config-if)# dialer string cdma

*** cdma ***

 

 

 

 

 

or

 

 

 

 

 

 

Router (config-if)# dialer group 2

*** gsm ***
