Example: Configuring Dialer Filters for Dial-on-Demand Routing Backup

In this example, you create a dialer filter called int-packet and a corresponding dialer filter rule called term1. Within term1, you configure an ICMP packet as the interesting packet. You then apply to the dialer filter to the dl0 interface.

To configure a dialer filter for dial-on-demand backup:

1. Create the dialer filter.

   [edit]user@host# edit firewall family inet dialer-filter int-packet

2. Create the dialer filter rule.

   [edit firewall family inet dialer-filter int-packet]user@host# set term term1 from protocol icmp then note

3. Select the dialer interface to apply to the filter.

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

4. Select the dialer filter and apply it to the dialer interface.

   [edit interfaces dl0 unit 0]user@host# set family inet filter dialer int-packet
