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 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.
Refer to the exhibit. On the basis of the configuration that is provided, how would the BGP updates that come from router R1 be replicated inside autonomous system 65200?() 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 R5B. None of the BGP updates that are received on router R2 will ever be received by router R5C. All BGP updates that are received on router R2 will not be sent to routers R3 and R4D. All BGP updates that are received on router R2 will be sent directly to router R5
