226 CHAPTER 16: IP R OUTING P ROTOCOL OPERATION■ Enabling RIP to Import Routes of Other Protocols■ Configuring the Default Cost for the Imported Route■ Setting the RIP Preference■ Setting Additional Routing Metrics■ Configuring Route FilteringEnabling RIP and Entering the RIP ViewPerform the following configurations in System ViewBy default, RIP is not enabled.Enabling RIP on a Specified NetworkFor flexible control of RIP operation, you can specify the interface and configure thenetwork on which the interface is located to the RIP network, so that these interfacescan send and receive RIP packets.Perform the following configurations in RIP View.After the RIP interface is enabled, you should also specify its operating networksegment, because RIP only operates on the interface when the network segment hasbeen specified. RIP does not receive or send routes for an interface that is not on thespecified network, and does not forward its interface route.When the network command is used for an address, the effect is to enable theinterface of the network with this address. For example, for network 129.102.1.1,you can see network 129.102.0.0 either using the display current-configurationcommand, or using the display rip command.By default, RIP is disabled on all interfaces.Configuring Unicast RIP MessagesRIP is a broadcast protocol. To exchange routing information with a non-broadcastnetwork, unicast transmission mode must be used.Perform the following configuration in the RIP View.By default, RIP does not send messages to unicast addresses.Table 202 Enabling RIP and Entering the RIP ViewOperation CommandEnable RIP and enter RIP view ripDisable RIP undo ripTable 203 Enabling RIP InterfaceOperation CommandEnable RIP on the specified network network network_addressDisable RIP on the specified network undo network network_addressTable 204 Configuring unicast RIP messagesOperation CommandConfigure unicast RIP message peer ip_addressCancel unicast RIP message undo peer ip_address
