Based on the following show ip bgp neighbor 10.1.1.1 output:
R1#show ip bgp neighbor
10.1.1.1 BGP neighbor is 10.1.1.1, remote AS 65102, external link BGP version 4, remote router ID 0.0.0.0 BGP state=Idle Last read 00:00:04, hold time is 180, keepalive interval is 60 seconds Received 0 messages, 0 notifications, 0 in queue Sent 0 messages, 0 notifications, 0 in queue Route refresh request: received 0, sent 0 Default minimum time between advertisement runs is 30 seconds For address family: IPv4 Unicast BGP table version 1, neighbor version 0Index 2, Offset 0, Mask 0x40 accepted prefixes
consume 0 bytes Prefix advertised 0, suppressed 0, withdrawn 0 Connections established 0; dropped 0 Last reset never External BGP neighbor not directly connected. No active TCP connection

A. The EBGP-multihop value for neighbor 10.1.1.1 is set to the default value.
B. There is an AS number configuration error.
C. The BGP session is using the loopback interface but the update-source is not set to specify the loopback interface.

C. If the route is learned from a client IBGP peer by the route reflector, it is reflected to all clients only, except the originating client.
D. If the route is learned from a non-client IBGP peer by the route reflector, it is reflected to EBGP peers and clients only.
