Exhibit:
A. The “No Sync” BGP configuration command is missing.
B. CK2 and CK3 are not using the loopback0 IP address as the source address for the BGP messages to each other.
C. The “network 2.0.0.0” BGP configuration command is missing on CK2 and the “network 3.0.0.0” BGP configuration command is missing on CK3 .
D. The “neighbor 2.2.2.2 ibgp-multihop 2” BGP configuration command is missing on CK3 and the “neighbor 3.3.3.3 ibgp-multihop 2” BGP configuration command is missing on CK2 .
