PBR Exceptions (Permit) To create an exception to a redirect list, use thepermit command. Exceptions are used when a forwarding decision should be based on the routing table rather than a routing policy. The 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. Because the order of rules is important, ensure that you configure any necessary sequence numbers. Never apply the permit statement because the redirect list covers all source and destination IP addresses. ip redirect-list rcl0 seq 5 redirect 2.2.2.2 ip any any seq 10 permit ip host 3.3.3.3 any To ensure the permit permit statement or PBR exception is effective, use a lower sequence number, as shown: ip redirect-list rcl0 seq 10 permit ip host 3.3.3.3 any seq 15 redirect 2.2.2.2 ip any any Create a Redirect List To create a redirect list, use the following commands. Create a redirect list by entering the list name. CONFIGURATION mode ip redirect-list redirect-list-name redirect-list-name: 16 characters. To delete the redirect list, use the no ip redirect-list command. The following example creates a redirect list by the name of xyz. Dell(conf)#ip redirect-list ? WORD Redirect-list name (max 16 chars) Dell(conf)#ip redirect-list xyz Create a Rule for a Redirect-list To set the rules for the redirect list, use the following command. You can enter the command multiple times and create a sequence of redirect rules. Use the seq nn redirect version of the command to organize your rules. Configure a rule for the redirect list. CONF-REDIRECT-LIST mode seq {number} redirect {ip-address | tunnel tunnel-id} [track }{ip-protocol-number | protocol-type [bit]} {source mask | any | host ip-address}{destination mask | any | host ipaddress} • number is the number in sequence to initiate this rule • ip-address is the Forwarding router's address • tunnel is used to configure the tunnel settings • tunnel-id is used to redirect the traffic 614 Policy-based Routing (PBR)
