Hi There,
I'm trying to backup several remote sites' wan connection with isdn to a central site ( a hub and spoke topology for ddr backup). I want the remote sites to call the central site when the wan link goes down but not the other way round. The central site has a pri E1 connection to a 3640 router. I have configured dialer watch at the remote site and it works ok when the central site is configured with a dialer group command and dialer remote name. I wanted to use rotary groups so that i can add more remote sites to the dialer profile config at the central site ( i was going to add more dialer map statements to the dialer interface as shown in my enclosed config).
With the rotary group and dialer map statement configured on the central site I am unable to get ip connectivity between the central and remote site. The remote router shows an isdn connection to the central site when i do 'show dialer' but pings don't show connectivity. This is the central site config:
