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. FTOS 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. In Figure 37-6, the permit statement is never applied because the redirect list covers all source and destination IP addresses. Figure 37-6.
