D. Tunneling the packets for the i BGP connection between R1 and R2

heir directly connected routers in au tonomous system 100. IGP has been configured on all routers in autonomous system 100 and they successfully exchange routing updates. Traffic originated in autonomous system 200 cannot reach the destination autonomous system 300. What configuration shoul d be done on the routers in autonomous system 100 in order for the traffic coming from autonomous system 200 to be forwarded to autonomous system 300？（）

C. IBGP session must be established between routers R1 R2 and R2 R3, and the synchronization must be turned on.

D. IBGP session mu st be established between routers R1 and R3, and the synchronization must be turned off.

E. IBGP speakers within autonomous 100 must be fully meshed, and the synchronization must be turned off.

F. IBGP session must be established between routers R1 and R3, and the synchronization must be turned on.

A.R3,R4,R6

B. R2,R3,R6,R7

C. R1 through R8

D. R3,R4,R5,R6

E. R2,R3,R4,R6,R7

Routers R1 and R2, currently EIGRP neighbors over their Fa0/0 interfaces (respectively),both use EIGRP authentication. Tuesday at 8 p.m. the neighborship fails.Which of the following wo uld not be useful when investigating whether authenticationhad anything to do with the failure？（）

A. debug eigrp packet

B. show key chain

C. show ip eigrp neighbor failure

D. show clock

A.R1 can learn EIGRP routes from R2, but R2 cannot learn EIGRP routes from R1

B.R1 can send IP packets to R2, but R2 cannot send IP packets to R1

C.R2 no longer learns EIGRP routes from R1 for routes not connected to R1

D.R1 no longer replies to R2‘s Query messages

E.R2n o longer sends to R1 Query messages

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

ter R1 does not receive a default route to router R2 as in tended. Which configuration change would ensure that R1 would receive a default route from R2？ （）

A. Add the area 1 stub command on routers R1.

B. Add the always keyword to the default - information originate configuration command on router R2.

C. Remov e the default information originate configuration command from router R2 and place it on router R1.

D. Add the ip route 5.0.0.0 255.255.255.0 0.0.0.0 command to router R2.

Routers R1 and R2, OSPF neighbors in area 0 over their Fa0/0 interfaces (respectively), currently both successfully use OSPF MD5 authentication. The OSPF configuration includes the area 0 authentication command under the router ospf 1 command.Which of the following commands must have been configur ed on R1‘s Fa0/0 interface？（）

A. ip ospf authentication null

A. All BGP updates that are received on router R 2 will be sent to routers R3 and R4. Routers R3 and R4 will then forward those BGP updates to router R5

B. None of the BGP updates that are received on router R2 will ever be received by router R5

C. All BGP updates that are received on router R2 will not be sent to routers R3 and R4
