A recursive route is a route for which the immediate next-hop address is learned dynamically through a routing protocol and acquired through a route lookup in the routing table. The user can configure multiple recursive routes in a redirect list by entering multiple seq redirect statements with the same source and destination address and specify a different next-hop IP address. In this way, the recursive routes are used as different forwarding routes for dynamic failover. If the primary path goes down and the recursive route is removed from the routing table, the seq redirect statement is ignored and the next statement in the list with a different route is used. 682 Policy-based Routing (PBR)
