Hello all,
I have two routers with IOS 12.0(27) on it. There's a leased line which works with the ser0-interface only and there's a ISDN-line with two b-channels which works (mostly) with the bri0-if only.
Now I want to do/to have the following to get work:
the leased-line with the ser0-interfaces on both sides should be for the basic traffic. After reaching a threshold, the first b-channel should come up.
I tried to do this via a dialer rotary-group and put the ser0 and bri0-if in it.
I worked, until the dialer-idle time was reached and then the VirtualAcces-IF goes down and never comes up again. After resetting the external X.21-Modem for the ser0-IF on one side the VirtualAccess-IF comes up again and so on.
In this case the bri0 did not come up to handle the traffic instead of the ser0-IF.
Switching on the debugging I could see, that the ser0-IF got the dialer-string with the phone-number for the bri0-if, maybe that's the reason for crashing the external modem.
I got help in the web in that way, that I should configure the ser0 with dialer dtr, dialer pool-member 1, dialer priority 10 and the bri0 with dialer pool-member 1 and dialer priority 5. It worked for the ser0, but not for the bri0-IF.
Now, is it possible to combine the leased-line for basic traffic with a ISDN-line in that way using the dialer threshold and dialer rotary-group?
What is an other possibility for expanding the bandwith using my hardware?
I post the config of the both routers - maybe it helps, and maybe anyone knows a way to do this...
