In the following example, the redistribute command calls the route map static ospf to redistribute only certain static routes intoOSPF. According to the route map static ospf, only routes that have a next hop of Tengigabitethernet interface 1/1/1/1 and that havea metric of 255 are redistributed into the OSPF backbone area.NOTE: When re-distributing routes using route-maps, you must create the route-map defined in the redistribute commandunder the routing protocol. If you do not create a route-map, NO routes are redistributed.Example of Calling a Route Map to Redistribute Specified Routesrouter ospf 34default-information originate metric-type 1redistribute static metric 20 metric-type 2 tag 0 route-map staticospf!route-map staticospf permit 10match interface TenGigabitEthernet 1/1/1/1match metric 255set level backboneConfigure a Route Map for Route TaggingOne method for identifying routes from different routing protocols is to assign a tag to routes from that protocol.As the route enters a different routing domain, it is tagged. The tag is passed along with the route as it passes through different routingprotocols. You can use this tag when the route leaves a routing domain to redistribute those routes again. In the following example, theredistribute ospf command with a route map is used in ROUTER RIP mode to apply a tag of 34 to all internal OSPF routes that areredistributed into RIP.Example of the redistribute Command Using a Route Tag!router ripredistribute ospf 34 metric 1 route-map torip!route-map torip permit 10match route-type internalset tag 34!Continue ClauseNormally, when a match is found, set clauses are executed, and the packet is then forwarded; no more route-map modules are processed.If you configure the continue command at the end of a module, the next module (or a specified module) is processed even after a matchis found. The following example shows a continue clause at the end of a route-map module. In this example, if a match is found in theroute-map “test” module 10, module 30 is processed.NOTE: If you configure the continue clause without specifying a module, the next sequential module isprocessed.Example of Using the continue Clause in a Route Map!route-map test permit 10match commu comm-list1set community 1:1 1:2 1:3set as-path prepend 1 2 3 4 5continue 30!112 Access Control Lists (ACLs)
