esign the entire route map. You can enter individual clauses at any time. parser will insert them in the proper order within the configuration. Each clause can be either a permit or a deny clause, with permit being the default. How the permit and deny values affect the processing of the route map depends on the route map's application. The next section presents an example of policy routing using route maps. Within each clause, there are two basic types of commands: match Selects routes or packets based on the criteria listed. Modifies information in either packets or routing protocol tables based on the criteria listed. match commands are evaluated in order of entry within the clause. match entries can be evaluated in two ways: multiple match entries on a single line will be considered logical OR tests, while multiple match entries on separate lines will be considered logical AND tests. This code configures the route map GAD with the default clause values of permit and 10. The first match tests for the IP address matching access list 101 OR 102 OR 103. The second match tests for the packet between 200 and 230 bytes in length: route-map GAD permit 10 match ip address 101 102 103 match length 200 230 set ip next-hop 10.10.10.10 By nature of the way route maps operate, any of the three access lists (ACLs) can be matched, AND the packet length must match the second test for the set command to be executed. If no match is made, no action is taken for this clause, and the next higher- numbered clause in the route map is evaluated. If no match command is present in the clause, all packets or routes match. In this case, the set command is executed on every packet or route. If no set command is present, no action is taken beyond the scope of the clause itself. This is useful when limiting redistribution in routing protocols-because you don't want to change anything, there doesn't need to be a set command. The route map will permit route redistribution until a deny clause is encountered. The following route map can be appli
