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.
