Dell(conf-redirect-list)#do show ip redirect-list IP redirect-list xyz: Defined as: seq 5 redirect 3.3.3.3 ip host 222.1.1.1 host 77.1.1.1 Applied interfaces: None 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 displays the correct method for applying multiple rules to one list. Creating multiple rules for a redirect-list: Dell(conf)#ip redirect-list test Dell(conf-redirect-list)#seq 10 redirect 10.1.1.2 ip 20.1.1.0/24 any Dell(conf-redirect-list)#seq 15 redirect 10.1.1.3 ip 20.1.1.0/25 any Dell(conf-redirect-list)#seq 20 redirect 10.1.1.3 ip 20.1.1.128/24 any Dell(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 Dell(conf-redirect-list)# NOTE: Dell Networking OS supports the use of multiple recursive routes with the same sourceaddress and destination-address combination in a redirect policy on an 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. 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. PBR Exceptions (Permit) Use the command permit to create an exception to a redirect list. Exceptions are used when a forwarding decision should be based on the routing table rather than a routing policy. Dell Networking OS assigns the first available sequence number to a rule configured without a sequence number and inserts the rule into the PBR CAM region next to the existing entries. Since the order of rules is important, ensure that you configure any necessary sequence numbers. The permit statement is never applied because the redirect list covers all source and destination IP addresses.
