Thanks for showing an interest!
Here's the situation, We have a remote site with a frame relay connection (via ser0) which we want to back up with an isdn backup line using ddr and a dialer profile to the main site.
Here is the config of the router

One problem is that the dialer interface is not dialing out when I ping an ip address on the main site from the remote site after having shut down the frame relay serial interface (administritively). I have tried pinging directly from the remote router and the dialer interface is not dialing out. The bri interface is working as it brings itself up to connect to the ntp server every couple of minutes (which is another problem).
The floating static default route is shown in the route table after having shut down the serial interface along with the subnets of the ethernet and dialer interfaces (and all the eigrp routes disappear).
If i do a debug dialer packets i see the following:
Jul 25 10:30:56: Dialer0 DDR: ip (s=10.2.176.10, d=224.0.0.10), 60 bytes, outgoing uninteresting (list 101)
Jul 25 10:31:00: Dialer0 DDR: ip (s=10.2.176.10, d=224.0.0.10), 60 bytes, outgoing uninteresting (list 101)
but no sign of the ping attempts that are running on the network. I would have expected to see the pings in the debug as interesting traffic but there is no sign of them.
Please let me know if you need any further information.
Rgds,
Martin
