Refer to the exhibit. Router B is performing bidirectional redistribution between EIGRP an d OSPF.The network 10.100.1.0/24 should not be reachable from the 10.100.9.0/24 network. However, it needs to be reachable from any network within the EIGRP domain. All other networks should be seen in both domains. Which change to router B would accom plish these goals?（）A. Under the EIGRP process, insert the distribute - list block_net_1 out ospf 1 command.B. Under the OSPF process, insert the distribute - list block_net_1 in serial1/0 command.C. Under the EIGRP process, insert the distribute - list block_net_1 in serial1/0 command.D. Under the OSPF process, insert the distribute - list block_net_1 out eigrp 1 command.

What is the purpose of the OSPF router ID in a OR／BOR election?() A. It is used with the OSPF priority values to determine which OSPF router will become the DR or BOR in a point-to-point networkB. It is used with the OSPF priority values to determine which interface will be used to form a neighbor relationship with another OSPF routerC. It is used with the OSPF priority values to determine which router will become the DR or BOR in a multi access networkD. It is used to determine which interfaces will send Hello packets to neighboring OSPF routers
Refer to the exhibit. OSPF is configured on all routers in the network. On the basis of the show ip ospf n eighbor output, what prevents R1 from establishing a full adjacency with R2? () A.

Routers R1 and R2 are configured as stub routers for OSPF area 1 and OSPF area 2.D. Router R1 and R2 are configured for a virtual link between OSPF area 1 and OSPF area 2.E. The Hello parameters on routers R1 and R2 do not m atch.

多选题Refer to the graphic. R1 is unable to establish an OSPF neighbor relationship with R3. What are possible reasons for this problem?（）AAll of the routers need to be configured for backbone Area 1.BR1 and R2 are the DR and BDR, so OSPF will not establish neighbor adjacency with R3.CA static route has been configured from R1 to R3 and prevents the neighbor adjacency from being established.DThe hello and dead interval timers are not set to the same values on R1 and R3.EEIGRP is also configured on these routers with a lower administrative distance.FR1 and R3 are configured in different areas.
