C. Configure loopback interfaces on R1 and R4 to provide the update source address for BGP packets.

D. Configure only one neighbor relationship between R1‘s 192.168.1.2 interface and R4‘s 172.16.10.2 interface.

Refer to the exhibit. All routers have Protocol Independent Multicast (PIM) enabled interfaces. On the basis of the configuration provided on routers R1 and R2, which router will take on the func tion of rendezvous point (RP) for the multicast network? （）

A. both routers R1 and R2

B. router R1

C. router R2

D. none of the routers since they are not configured with static RP

Refer to the exhibit. OSPF has been configured on all routers in the network. However, router 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.

A. The no auto - summary command has not been issued under the EIGRP process on both routers.

B. Interface E0 on router R1 has not been configured with a secondary IP address of 10.1.2.1/24.

C. EIGRP cannot exchange routing updates with a neighbor‘s router interface that is configured with tw o IP addresses.

D. EIGRP cannot form neighbor relationship and exchange routing updates with a secondary address.

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

D. All BGP updates that are received on router R2 will be sent directly to router R5

Refer to the exhibit. Routers R1 and R2 have been configured to operate with OSPF. Routers R1 and R3 have been configured to operate with RIP. After configuring the redistribution between OSPF a nd RIP on R1, no OSPF routes are distributed into RIP. What should be done to correct this problem? （）

A. The redistribution command should be reentered with the match route - type parameter included.

B. The redistribution command should be reentered wit h the route - map map - tag parameter included.

C. The redistribution command should be reentered with the metric metric - value parameter included.

D. Routes will first need to be distributed into another protocol, and then into RIP.

Refer to the exhibit. Autonomous systems 200 and 300 have EBGP sessions established with their 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?（）

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

B. IBGP speakers within autonomous 100 must be fully meshed, and the synchronization must be turned on.

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. Router R1 will only establish full adjacency with the DR and BDR on broadcast multi- access networks.

B. Router R2 has been elected as a DR for the broadcast multiaccess network in OSPF area 1.

C. 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.

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
