Enter the BRI interface, encapsulation method (PPP), authentication type, target

Step 4

router's IP address and ISDN number to dial, and the dialer group number:

Router (config)# interface bri port_number

Router (config-if)# encapsulation ppp

Router (config-if)# ppp authentication chap

Router (config-if)# dialer map ip targetrouter_ipaddress

targetrouter_phonenumber

Router (config-if)# dialer-group groupnumber

Do not use periods or hyphens when you enter dialing numbers.

Note

Some ISDN switch types, such as Basic NI1 or DMS-100 switch service, require

Step 5

you to configure a service profile identifier (SPID). Enter the SPID information as

follows, substituting the appropriate entries for your installation:

Router (config-if)# isdn spid1 SPID_no phone_number

Router (config-if)# isdn spid2 SPID_no phone_number

To set up a second B channel for bandwidth on demand, enter the load-threshold

Step 6

command to set the ISDN load threshold. The load threshold determines the

percentage of network loading at which the second ISDN B channel is triggered.

The value ranges from 1 to 255 (100 percent).

Router (config-if)# dialer load-threshold 128

In this example, the value of 128 means that when the first B channel reaches

50 percent of its bandwidth capacity (128 equals 50 percent of 255), the second B

channel will be activated to assist with the bandwidth load.

Enter the access-list command to configure the ISDN line to come up whenever

Step 7

IP packets are to be sent:

Router (config-if)# access-list access-list-number permit ip

sourcerouter-ipnetwork sourcerouter-subnetmask

targetrouter-ipnetwork targetrouter-subnetmask

Router (config)# dialer-list groupnumber list access-list-number
