In the following example, the redistribute command calls the route map static ospf to redistribute only certain static routes into OSPF. According to the route map static ospf, only routes that have a next hop of Gigabitethernet interface 0/0 and that have a metric of 255 will be redistributed into the OSPF backbone area. Note: When re-distributing routes using route-maps, the user must take care to create the route-map defined in the redistribute command under the routing protocol. If no route-map is created, then NO routes are redistributed. router ospf 34 default-information originate metric-type 1 redistribute static metric 20 metric-type 2 tag 0 route-map staticospf ! route-map staticospf permit 10 match interface GigabitEthernet 0/0 match metric 255 set level backbone Configure a route map for route tagging One 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 and that tag is passed along with the route as it passes through different routing protocols. This tag can then be used when the route leaves a routing domain to redistribute those routes again. In the following example, the redistribute ospf command with a route map is used in the ROUTER RIP mode to apply a tag of 34 to all internal OSPF routes that are redistributed into RIP. ! router rip redistribute ospf 34 metric 1 route-map torip ! route-map torip permit 10 match route-type internal set tag 34 ! Continue clause Normally, when a match is found, set clauses are executed, and the packet is then forwarded; no more route-map modules are processed. If the continue command is configured at the end of a module, the next module (or a specified module) is processed even after a match is 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 the route-map "test" module 10, module 30 will be processed. 142 | Access Control Lists (ACLs)
