• If no match is found in a route-map sequence, the process moves to the next route-map sequence until a match is found, or there are no more sequences. • When a match is found, the packet is forwarded and no more route-map sequences are processed. • If a continue clause is included in the route-map sequence, the next or a specified route-map sequence is processed after a match is found. Configuration Task List for Route Maps Configure route maps in ROUTE-MAP mode and apply the maps in various commands in ROUTER RIP and ROUTER OSPF modes. The following list includes the configuration tasks for route maps, as described in the following sections. • Create a route map (mandatory) • Configure route map filters (optional) • Configure a route map for route redistribution (optional) • Configure a route map for route tagging (optional) Creating a Route Map Route maps, ACLs, and prefix lists are similar in composition because all three contain filters, but route map filters do not contain the permit and deny actions found in ACLs and prefix lists. Route map filters match certain routes and set or specific values. To create a route map, use the following command. • Create a route map and assign it a unique name. The optional permit and deny keywords are the actions of the route map. CONFIGURATION mode route-map map-name [permit | deny] [sequence-number] The default is permit. The optional seq keyword allows you to assign a sequence number to the route map instance. Configured Route Map Examples The default action is permit and the default sequence number starts at 10. When you use the keyword deny in configuring a route map, routes that meet the match filters are not redistributed. To view the configuration, use the show config command in ROUTE-MAP mode. Dell(config-route-map)#show config ! route-map dilling permit 10 Dell(config-route-map)# You can create multiple instances of this route map by using the sequence number option to place the route maps in the correct order. Dell Networking OS processes the route maps with the lowest sequence number first. When a configured route map is applied to a command, such as redistribute, traffic passes through all instances of that route map until a match is found. The following is an example with two instances of a route map. The following example shows matching instances of a route-map.
