2.OSPF is configured over a Frame Relay network as shown in the exhibit. All PVCs are active.However, R1 and R3 fail to see all OSPF routes in their routing tables. The show ip ospf neighbor command executed on R2 shows the state of t he neighbors. What should be done to fix the problem? （）A. The ip ospf network broadcast command should be configured on each Frame Relay interfaceB. The ip ospf network non -broadcast command should be configured on each Frame Relay interfaceC. Th e ip ospf priority value on the spoke routers should be set to 0D. The ip ospf priority value on the hub router should be set to 0E. The neighbor command should be configured under the OSPF routing process on all routers

3.On your OSPF network, routers TK1 and TK2 belong to the same Ethernet network. However, they are unable to establish an adjacency over this link. While troubleshooting this problem, you issue the "show ip ospf interface Ethernet 0"command on each router. The output from these commands is displayed below:What is the underlying cause of the routers failing to become adjacent?（）A. The OSPF area is misconfigured.B. The priority on TK2 should be set lower.C. The cost on TK2 should be set lower.D. The hello and dead timers are misconfigured.E. You need to add a backup designated router to the network.F. The OSPF process ID numbers do not match.

4.Routers R1 and R2, OSPF neighbors in area 0 over their Fa0/0 interfaces (respectively), currently both successfully use OSPF MD5 authentication.

    正确答案: DEV表示工作点距喘振控制线距离；
    DEV>0工作点在喘振控制线SCL右侧工作防喘振阀有一定开度，此时安全但浪费能源；
    DEV<0工作总在喘振控制线的左侧，负值越大，越远离安全*区，此时输出应开阀增大安全*区域；
    DEV=0工作总在喘振控制线上工作，此时系统最节能，回流量防空量降到最低限度。
