www.dell.com | support.dell.com 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 Figure 6-26, 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. Figure 6-26. Tagging OSPF Routes Entering a RIP Routing Domain ! 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. Figure 6-27 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. Note: If the continue clause is configured without specifying a module, the next sequential module is processed. Figure 6-27.
