Configuring the routerOSPF commandsUse the following commands to configure OSPF. For more information about these commands,see Avaya G350 Media Gateway CLI Reference, 555-245-202.●●●●●●●●●●●Use the area command to configure the OSPF area ID of the router. Use the no form ofthe command to delete the OSPF area id.Use the default-metric command to set the interface OSPF route metric value. Usethe no form of this command to restore the default value.Use the ip ospf authentication-key command to configure the interfaceauthentication password. Use the no form of this command to remove the OSPFpassword.Use the ip ospf cost command to configure the interface metric. Use the no form ofthis command to set the cost to its default value.Use the ip ospf dead-interval command to configure the interval before declaringthe neighbor as dead. Use the no form of this command to set the dead-interval to itsdefault value.Use the ip ospf hello-interval command to specify the time interval between hellopackets sent by the router. Use the no form of this command to set the hello-interval to itsdefault value.Use the ip ospf network point-to-multipoint command to specify the networktype for the interface. Use the no form of the command to return the interface to the defaultvalue.Use the ip ospf priority command to configure interface priority used in DR election.Use the no form of this command to set the OSPF priority to its default value.Use the ip ospf router-id command to configure the router ID. Use the no form ofthis command to return the router ID to its default value.Use the network command to enable OSPF in a network. Use the no form of thiscommand to disable OSPF in a network. The default value is disabled.Use the passive-interface command to suppress OSPF routing updates on aninterface. This is used to allow interfaces to be flooded into the OSPF domain as OSPFroutes rather than external routes.Note:●Note:You must also use the network command, in conjunction with thepassive-interface command, to make the network passive.Use the redistribute command to redistribute routing information from other protocolsinto OSPF. Use the no form of this command to disable redistribution by OSPF.196 Administration of the Avaya G350 Media Gateway

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
