hallo
I have a main office with a cisco 2600 router connected to BRI interfaces.
Remote offices use cisco761 router to connect to main office cisco 2600.
The main office router must only respond to remote calls.
I need bandwidth on demand so when the load on a B channel passes a threshold a second B channel will be used.
* This is part of the cisco2600 config

interface BRI1/0
description 'connected to Bassano -Set'
no ip address
no ip directed-broadcast
encapsulation ppp
dialer pool-member 1

bandwidth ?

WHICH ARE THE VALUES FOR THE FOLLOWING PARAMETERS IF I WHANT THAT THE SECOND B CHANNEL GOES UP WHEN THE FIRST REACHES 60Kbps ?
bandwidth ?
dialer load-threshold ?
demand 2 threshold= ? duration=1 source=both
timeout 2 threshold= ? duration=300 source=both
THANKs

For 60% load, your threshold should be set to 255 * 0.6 = 1531. I dont think you need to set bandwidth as well.
Thanks.

You need to enter following command if you want the first link loaded to (threshold=60) 60kbps for continuously 300 secs (duration=300) before 2nd b channel will be dialed.
demand 2 threshold=60 duration=300 source=both
Here is the link which explains how to use that command and what are thoes parameters means.

Ok for the cisco760 but for cisco2600 dialer interface what are the values for:
- bandwidth
- dialer load-threshold
Can I use "bandwidth 128" and "dialer load-threshold 120" (60*255/128) ?
