DDR Backup holdtown timers?

[admin_2]

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?

I'm assuming you have no control over

the CPE device? If so, the only way is

to either move the AAA server so that it

is more redundant, or add local authentication

to the 5300.

If you have control over the CPE dialing,

then have a look at dialer redial.
