We have a few sites where we have deployed 1700 routers behind the ISP's CPE. We have set up VPNs back to corporate. Has anyone found a way to use GRE/EIGRP/something to cause the router to dial when the primary goes down and re-establish the VPN? I also need to figure out how to strip the DDR connection down when the ISP connection has been re-established. Any ideas?
