Example: Configuring Dialer Interfaces

In this example, you create the dl0 dialer interface and set the encapsulation type for the interface to Cisco HDLC. You set the hold-time value to 60 milliseconds. When configuring delay intervals, you set the activation delay to 60 seconds, the deactivation delay to 30 seconds, and the redial delay to 5 seconds. Additionally, you create the isdn-dialer-group dialer pool, set the dial string to 5551212, specify 172.20.10.2 as the source IP address for the dialer interface, and specify 172.20.10.1 as the destination IP address for the dialer interface. (The destination IP address is optional.)

To configure a logical dialer interface:

1. Create and describe the interface.

   [edit]user@host# edit interfaces dl0user@host# set description T1-backup

2. Configure the encapsulation mode.

   [edit interfaces dl0]user@host# set encapsulation cisco-hdlc

3. Enter the hold-time values.

   [edit interfaces dl0]user@host# set hold-time down 60user@host# set hold-time up 60

4. Create the logical unit.

   [edit interfaces dl0]user@host# edit unit 0

5. Configure the delay intervals.

   [edit interfaces dl0 unit 0 dialer-options]user@host# set activation-delay 60user@host# set deactivation-delay 30user@host# set redial-delay 5

6. Configure the dialer pool.

   [edit interfaces dl0 unit 0 dialer-options]user@host# set pool isdn-dialer-group

7. Specify which remote destination to call.

   [edit interfaces dl0 unit 0 dialer-options]user@host# set dial-string 5551212

8. Configure source and destination IP addresses for the dialer interface.

   [edit]user@host# set interfaces dl0 unit 0 family inet address 172.20.10.2 destination 172.20.10.1
