Route redistribution●●●●●●Use the router ospf command to enable OSPF protocol on the system and to enter therouter configuration context. Use the no form of this command to restore the default value,disable OSPF globally.Use the show ip ospf command to display general information about OSPF routing.Use the show ip ospf database command to display lists of information related to theOSPF database for a specific router.Use the show ip ospf interface command to display the OSPF-related interfaceinformation.Use the show ip ospf neighbor command to display OSPF neighbor information on aper-interface basis.Use the timers spf command to configure the delay between runs of OSPF’s (SPF)calculation. Use the no form of this command to restore the default value.Route redistributionRoute redistribution is the interaction of multiple routing protocols. OSPF and RIP can beoperated concurrently in the G350. In this case, you can configure the G350 to redistributeroutes learned from one protocol into the domain of the other routing protocol. Similarly, staticroutes can be redistributed to RIP and OSPF.Note:Note:Take care when you configure route redistribution. It involves metric changes andmight cause routing loops in the presence of other routes with incompatibleschemes for route redistribution and route preferences.The G350 scheme for metric translation in route redistribution is as follows:● Static to RIP metric configurable (default 1)● OSPF internal metric N to RIP metric (default 1)● OSPF external type 1 metric N to RIP metric (default 1)● OSPF external type 2 metric N to RIP metric (default 1)● Static to OSPF external type 2, metric configurable (default 20)● RIP metric N to OSPF external type 2, metric (default 20)● Direct to OSPF external type 2, metric (default 20)By default, the G350 does not redistribute routes between OSPF and RIP. Redistribution fromone protocol to the other can be configured. Static routes are, by default, redistributed to RIPand OSPF. The G350 allows the user to globally disable redistribution of static routes to RIP,and separately to globally disable redistribution of static routes to OSPF. In addition you canconfigure, on a per static route basis, whether the route is to be redistributed to RIP and OSPF,Issue 3 January 2005 197
