Hi Peng,
Requirement 1:
R1 with dialer-group and string and R2 without the string. Don4t forget
dialer idle-timeout 0 in R2. Use CHAP!!!
Requeriment 2:
R1 and R2 in the ISDN link don4t run any kind of Routing protocol, so you
can do 2 things:
****R1 with dialer-watch to only one network and a floating default route
pointing to the BRI interface.R2 with a static route to the networks
directly conected to R1.
****R1 with back interface serial x and a default route pointing to the BRI
interface. R2 R2 with a static route to the networks directly conected to
R1.
I think one of them is the solution!!!
Rgds,
Sergio
