DDR Problem

I have 1700 Cisco ADSL router with ISDN backup, I configured the router so that most of the traffic goes out via the ADSL link, but some traffic must use the ISDN to get emails from the HQ, the only problem is that the router doesn't dial up at all regardless of what I do, see ISDN Status output below, from this you can see there's nothing wrong with the ISDN, and if I use BRI to dial it dials but as soon as I configure the dialer profile it ignores everything, so does anyone know why?


Global ISDN Switchtype = basic-net3
ISDN BRI0 interface
dsl 0, interface ISDN Switchtype = basic-net3
Layer 1 Status:
ACTIVE
Layer 2 Status:
TEI = 115, Ces = 1, SAPI = 0, State = MULTIPLE_FRAME_ESTABLISHED
Layer 3 Status:
0 Active Layer 3 Call(s)
Active dsl 0 CCBs = 0
The Free Channel Mask: 0x80000003
Number of L2 Discards = 0, L2 Session ID = 19
Total Allocated ISDN CCBs = 0

how do u define what traffic hits the serial link and what traffic hits the BRI link.. i am guessing u are using route-maps.. if so, then please paste a copy of your configuration..

however, generally, if you want to increase your bandwidth bu adding your BRI interface to the serial link, u will have to tell your serial interface when to dial the BRI link - use this command:

conf t
int s0
backup load 90 5

this tells your serial interface to kick-in once traffic levels fill it to about 90%, which is 230/255... 5 is the 5% that is aggregate load...

once the load of both interfaces gets to 13/255, the BRI link will be dropped and all traffic will be routed via the serial interface..

good luck..
 
For some strange reason changing the IOS to a later one seems to solve my problem, and now that the traffic that is going to the HQ brings the ISDN line up as expected,

Thanks for your help
