Table 8-9. Command Example fields: show ip bgp neighbors
Lines beginning with Description
BGP neighbor Displays the BGP neighbor address and its AS number. The last
phrase in the line indicates whether the link between the BGP router
and its neighbor is an external or internal one. If they are located in the
same AS, then the link is internal; otherwise the link is external.
BGP version Displays the BGP version (always version 4) and the remote router
ID.
BGP state Displays the neighbor’s BGP state and the amount of time in
hours:minutes:seconds it has been in that state.
Last read This line displays the following information:
• last read is the time (hours:minutes:seconds) the router read a
message from its neighbor
• hold time is the number of seconds configured between messages
from its neighbor
• keepalive interval is the number of seconds between keepalive
messages to help ensure that the TCP session is still alive.
Received messages This line displays the number of BGP messages received, the number
of notifications (error messages) and the number of messages waiting
in a queue for processing.
