How to configure ISDN and backup leases on routers

Routing expert Sudhanshu Gupta explains how to configure ISDN and backup leases on routers in this expert answer.

The easiest way to configure the backup link is to have floating static routes. If you are running any dynamic routing protocol, it will automatically provide connectivity in case of connectivity failure.
