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.The IBGP routers must always be fully meshed.

B.The IBGP routerscan be in a different AS.

C.The IBGP routersmust be directly connected.

D.TThe IBGP routersdo not need to be directly connected.

E.None of the other alternatives apply are true
