Refer to the exhibit. Router R1 is reporting that its BGP neighbor adjacency to router R2 is down, but its state is Active. Which configuration must be applied to routers R1 and R2 to fix the problem?
A. R1 router bgp 5400 neighbor 11.11.11.11 remote-as 5400 neighbor 11.11.11.11 update-source Loopback0 R2 router bgp 5400 neighbor 11.11.11.12 remote-as 5400 neighbor 11.11.11.12 update-source Loopback0
B. R1 router bgp 5400 neighbor 2.2.2.2 remote-as 5400 neighbor 2.2.2.2 update-source Loopback0 R2 router bgp 5400 neighbor 1.1.1.1 remote-as 5400 neighbor 1.1.1.1 update-source Loopback0
C. R1 router bgp 5400 neighbor 2.2.2.2 remote-as 5400 R2 router bgp 5400 neighbor 1.1.1.1 remote-as 5400
D. R1 router bgp 5400 neighbor 1.1.1.1 remote-as 5400 neighbor 1.1.1.1 update-source Loopback0 R2 router bgp 5400 neighbor 2.2.2.2 remote-as 5400 neighbor 2.2.2.2 update-source Loopback0
Correct Answer: D
