A.B.C.D Destination address any Any destination host host A single destination host IP address of forwarding router IP protocol number Source address and mask Destination address and mask Multiple rules can be applied to a single redirect-list. The rules are applied in ascending order, starting with the rule that has the lowest sequence number in a redirect-list. Figure 37-5 displays the correct method for applying multiple rules to one list. Figure 37-5. Creating multiple rules for a redirect-list FTOS(conf)#ip redirect-list test FTOS(conf-redirect-list)#seq 10 redirect 10.1.1.2 ip 20.1.1.0/24 any FTOS(conf-redirect-list)#seq 15 redirect 10.1.1.3 ip 20.1.1.0/25 any FTOS(conf-redirect-list)#seq 20 redirect 10.1.1.3 ip 20.1.1.128/24 any FTOS(conf-redirect-list)#show config ! ip redirect-list test seq 10 redirect 10.1.1.2 ip 20.1.1.0/24 any seq 15 redirect 10.1.1.3 ip 20.1.1.0/25 any seq 20 redirect 10.1.1.3 ip 20.1.1.0/24 any FTOS(conf-redirect-list)# Note: Starting in release 8.4.1.2, FTOS supports the use of multiple recursive routes with the same source-address and destination-address combination in a redirect policy on an E-Series ExaScale router. 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.You 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. 806 | Policy-based Routing
