Hello,
i have the Szenario below:
spoke cisco 1841 over DSL on hub cisco 1841. This connection works fine with GRE an flowting Route.
For this connection i have to configure an ISDN Backup.
The Backup works fine, if i make a connection direct to the BRI of the Hub
Router. But i have to configure an ISDN Backup over an ISP, this mean, that the spoke setup a connection over the Internet to the DSL Tunnel on the Hub.
Can anybody tell me, how i do to configure the router, that the Backup runs over the Internet?
Thanks in advance
Lorenz
