Configuring ISDN BRI Dialer Interfaces with Quick Configuration

When ISDN BRI interfaces are installed on the Services Router, links to ISDN Quick Configuration pages for dialer options are displayed on the Interfaces Quick Configuration page as shown in Figure 23.

You can use these Quick Configuration pages to configure an ISDN BRI dialer interface for either dial backup or dialer watch. For dial backup you specify the serial interface to back up. For dialer watch you specify a watch list of one or more routes to monitor.

To configure ISDN BRI dialer interfaces with Quick Configuration:

  1. In the J-Web interface, select Configuration>Quick Configuration>Interfaces.

    A list of network interfaces installed on the Services Router is displayed.

  2. Click ISDN Dialer Options under the interfaces list.
  3. Select a backup method to configure on the dialer interface:
  4. Do one of the following:

    Figure 24 shows the ISDN Quick Configuration page for dialer logical interfaces.

  5. Enter information into the ISDN Quick Configuration page for dialer logical interfaces, as described in Table 101.
  6. Click one of the following buttons on the ISDN Quick Configuration page:
  7. To verify that the ISDN interface is configured correctly, see the JUNOS Enhanced Services Interfaces and Routing Configuration Guide.

Field

Function

Your Action

Configuring Dialer Interfaces

Logical Interface Description

Describes the logical interface.

Type a text description of the interface in the box.

IPv4 Addresses and Prefixes

Displays the IPv4 addresses for the interfaces to which the dialer interface is assigned.

Note: Ensure that the same IP subnet address is not configured on different dialer interfaces. Configuring the same IP subnet address on different dialer interfaces can result in inconsistency in the route and packet loss. Packets can be routed through any of the dialer interfaces with the IP subnet address, instead of being routed through the dialer interface to which the ISDN call is mapped.

Type an IP address and a prefix in the boxes. Click Add.

To delete an IP address, highlight it in the list, and click Delete.

Dialer Options

Activation Delay

Displays the time to wait before activating the backup interface once the primary interface is down.

Type a value, in seconds—for example, 30.

The default value is 0 seconds with a maximum value of 60 seconds.

Deactivation Delay

Displays the time to wait before deactivating the backup interface once the primary interface is up.

Type a value, in seconds—for example, 30.

The default value is 0 seconds with a maximum value of 60 seconds.

Dial String (required)

Displays the dialing number from your ISDN service provider.

Type the dialing number and click Add.

To delete a dial string, highlight it and click Delete.

Pool (required)

Displays a list of dialer pools configured on br-pim/0/port interfaces.

Select a dialer pool from the list.

Multilink Dialer Options

Load Interval

Defines the interval used to calculate the average load on the dialer interface for bandwidth on demand.

Type a value, in seconds—for example, 30.

The default value is 60 seconds with a range of 20–80. The value must be a multiple of 10.

Load Threshold

Defines the threshold at which an additional ISDN interface is activated for bandwidth-on-demand. You specify the threshold as a percentage of the cumulative load of all UP links.

Type a percentage—for example, 80.

The default value is 100 with a range of 0–100.

Backup Interface (for dial backup only)

Interface to Backup

Displays a list of interfaces for ISDN backup.

Select an interface from the list for ISDN backup.

Dialer Watch List (for dialer watch only)

IPv4 Addresses and Prefixes

Displays the IPv4 addresses in the list of routes to be monitored by the dialer interface.

Type an IP address and a prefix in the boxes. Click Add.

To delete an IP address, highlight it in the list, and click Delete.
