    Accepted Solution


    If you have two WAN links for active / passive failover, there are two possible solutions:

    Using static route: you can configure static routes to the same destination. The preferred route will have a lower Administrative Distance (AD) and the least preferred or backup route, will have a much higher AD.

    Using the offset command: here you increment the AD of the backup route within the definition of a routing process.
