Operation Manual – Routing ProtocolH3C S7500 Series Ethernet Switches Chapter 3 RIP Configuration3-5To do... Use the command... RemarksSpecify RIP versionon the interfacerip version { 1 | 2[ broadcast | multicast ] }RequiredBy default, the interface canreceive RIP-1 and RIP-2broadcast packets but sendonly RIP-1 packets. Whenspecifying the RIP version onan interface to RIP-2, you canalso specify the mode(broadcast or multicast) tosend RIP packets.3.4 RIP Route ControlIn actual implementation, it may be needed to control RIP routing information moreaccurately to accommodate complex network environments. By performing theconfiguration described in the following sections, you can:z Control route selection by adjusting additional routing metrics on interfacesrunning RIP.z Reduce the size of the routing table by setting route summary and disabling thereceiving of host routes.z Filter the received routes.z Set the preference of RIP to change the preference order of routing protocols.This order makes sense when more than one route to the same destination isdiscovered by multiple routing protocols.z Import external routes in an environment with multiple routing protocols and filterthe advertised routes.3.4.1 Configuration PrerequisitesBefore configuring RIP route control, perform the following tasks:z Configuring IP address on each interface, and make sure that all adjacent nodesare reachable with each otherz Configuring basic RIP functions3.4.2 Configuring RIP Route ControlI. Set the additional routing metrics of an interfaceAdditional routing metric is the routing metric (hop count) added to the original metricsof RIP routes on an interface. It does not change the metric value of a RIP route in therouting table, but will be added for incoming or outgoing RIP routes on the interface.Follow these steps to set additional routing metric:
