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?()
A

frame - relay map commands on R3 - R10 referencing the other routers in this group

B

Nine OSPF neighbor commands on each router

C

Nine OSPF neighbor commands on R1 and R2, with only two such commands on R3 - R10

D

R1 and R2 with ip ospf prio rity 1 commands to ensure they become DR and BDR

E

R3 - R10 with ip ospf priority 0 commands to ensure they do not become DR or BDR

考题 Traditional Internet access methods like dial-up were so slow that host computers were connected to the dial-up(71)at the customer premise over slow(72)ports. PPP was designed to run directly over these serial links. But with the advent of broadband Internet(73)technologies such as ADSL and cable modems there has been a considerable increase in the bandwidth delivered to the end users. This means that the Lost computers at the customer premise connect to the(74)or cable "modem" over a much faster medium such as Ethernet. It also means that multiple(75)can connect to the Internet through the same connection.A.bufferB.modemC.computerD.server
