BGP is perhaps the most widely used and dependable routing protocol on the Internet, and it even plays a significant role in linking large businesses.
In this case, redundant routing mechanisms and the fastest route failovers in the setup is significant.
Configure the following timers to the lowest values as needed to enable the fastest route failovers:
scan-time, advertisement-interval, keep-alive-timer, and holdtime-timer.
CLI Syntax:
# config router bgp
set scan-time 'integer' <----- Background scanner interval(sec), 0 to disable it.(integer= Minimum value: 5 Maximum value: 60, Default:60)
end
# config router bgp
# config neighbor/neighbor-group
edit 'ip'/'name'
set advertisement-interval 'integer' <----- Minimum interval(sec) between sending updates.(integer= Minimum value: 1 Maximum value: 600, default:30).
set keep-alive-timer 'integer' <----- Keep alive timer interval (sec).(integer= Minimum value: 0 Maximum value: 65535) (default: <Global BGP value>).
set holdtime-timer 'integer' <----- Number of seconds to mark peer as dead. (integer= Minimum value: 3 Maximum value: 65535, or special:<0>) (default: <Global BGP value>)
end
