Hi All !!
I need some help and advice if you have a moment......
I am going to use two Cisco 800 routers to bridge via an ISDN BRI line
between two offices.
I have configured the routers to do this using some configs which I apapted
from the cisco
site..... it works reasonably well..... thing is the routers tend to keep a
channel up constantly
even when no traffic is being sent......
When I first power up the routers channel 1 will be activated and it will
stay like this until
I send some traffic.... when traffic is sent channel 1 is dropped briefly
and then channels 1
and 2 are brought up..... I experience about a 15 second delay in bringing
up the connection
initially and then its fine.....
I want to try to keep costs down while this temporary solution is in
place.... can anyone tell me
is there is any refinements I can make to the configs below ??
Kind Regards, Peter.
