We want to backup a serial line, connected to a 7200, which, by itself, is connected to a radius-server. Via Ethernet, we have an as5300 connected to the 7200, where the ISDN backup should terminate. The problem is, that if the 7200 goes down, the effect is that
<p>a) backup ddr is triggered
<p>b) no connectivity to radius is available.
<p>So the CPE dials, and dials, and dials (about 15 times a minute, with no success of course).
any idea for this scenario? how can i configure a backoff, which dials for example 3 times, waits for 2 minutes, dials 3 times, waits for 4 minutes ... and so on?
