多选题Ten routers, R1 through R10, connect in a partial mesh over Frame Relay. For the mesh, R1 and R2 have PVCs connected to all other routers, but Routers R3 through R10 act as branch routers, with only two PVCs - one to R1 and one to R2. The routers u se IP subnet 10.1.1.0/24, with addresses 10.1.1.1, 10.1.1.2, and so on, through 10.1.1.10, respectively. The routers all use Inverse ARP to learn Frame Relay mapping information. All routers use a multipoint subinterface with network type point - tomultip oint nonbroadcast. A co - worker's implementation plan lists lots of configuration commands related to this design. The design states that all hosts should be able to ping all other hosts. Which commands are required for proper functioning of OSPF in this case?（）Aframe - relay map commands on R3 - R10 referencing the other routers in this groupBNine OSPF neighbor commands on each routerCNine OSPF neighbor commands on R1 and R2, with only two such commands on R3 - R10DR1 and R2 with ip ospf prio rity 1 commands to ensure they become DR and BDRER3 - R10 with ip ospf priority 0 commands to ensure they do not become DR or BDR
