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
