ISDN Dialup and Routing !!!

Hi, I have two Remote Sites with RouterB (1720) and RouterC (1720) respectively bothe will call to the HQ RouterA (2620) as required (DDR).

Q1. If I were to configure RouterA to be able to call to RouterB or RouterC as well (i.e. both way calling), do I coonfigure the three Routers then ?

Q2. For both way calling, how do I configure the routing for each router ?

Q3. Is there any sample configuration for such scenerio ?

Pls help out.

T.Q.

Re: ISDN Dialup and Routing !!!

1: On router A, you will need a dialer map or a dialer interface for each connecting router.

2: As you are using dial-up lines, you should applystatic routing on all three router to prevent unwanted calls due to routing updates.

3: I have a config that utilizes DDR as backup between three sites. Send me an email and I will return these configs to you.
