Youcan set a priority for RIPng manually. The smaller the value is, the higher the priority is.Follow these steps to configure a RIPng priority:To do… Use the command… RemarksEnter system view system-view —Enter RIPng view ripng [ process-id ] —Configure a RIPngprioritypreference [ route-policyroute-policy-name ] valueOptionalBy default, the RIPngpriority is 100.2.3.6 Configuring RIPng Route RedistributionFollow these steps to configure RIPng route redistribution:To do… Use the command… RemarksEnter system view system-view ––Enter RIPng view ripng [ process-id ] ––Configure a defaultrouting metric forredistributed routesdefault cost valueOptionalBy default, the default metricof redistribute routes is 0.Redistribute routesfrom another routingprotocolimport-route protocol[ cost cost-value |route-policyroute-policy-name ] *RequiredBy default, RIPng does notredistribute any otherprotocol route.
