Operation Manual – Routing ProtocolH3C S7500 Series Ethernet Switches Chapter 4 OSPF Configuration4-14To do... Use the command... RemarksConfigure the networktype of the OSPFinterfaceospf network-type{ broadcast | nbma |p2mp | p2p }RequiredBy default, the networktype of an interfacedepends on the physicalinterface.Note:z After an interface has been configured with a new network type, the originalnetwork type of the interface is removed automatically.z Note that, neighboring relationship can be established between two interfacesconfigured as broadcast, NBMA, or P2MP only if the interfaces are on the samenetwork segment.4.5.3 Setting an NBMA NeighborSome special configurations need to be done on an NBMA network. Since an NBMAinterface cannot discover the adjacent router by broadcasting Hello packets, you mustmanually specify the IP address of the adjacent router for the interface and specifywhether the adjacent router has the right to vote.Follow these steps to set an NBMA neighbor:To do... Use the command... RemarksEnter system view system-view —Enter OSPF view ospf [ process-id[ router-id router-id ] ] —Set an NBMA neighbor peer ip-address[ dr-priority dr-priority ]RequiredBy default, the priority forthe neighbor of an NBMAinterface is 1.4.5.4 Setting the DR Priority on an OSPF InterfaceYou can control the DR/BDR election on a broadcast or NBMA network by configuringthe DR priorities of interfaces.Follow these steps to set the DR priority on an OSPF interface:
