Command Remarks
572. Configure BGP
keepalive interval and
holdtime.
• Configure the global keepalive interval
and holdtime:
timer keepalive keepalive hold holdtime
• Configure the keepalive interval and
holdtime for a peer or peer group:
peer { group-name | ip-address } timer
keepalive keepalive hold holdtime
Optional.
By default, the keepalive
interval is 60 seconds, and
holdtime is 180 seconds.
1504BConfiguring the interval for sending the same update
A BGP router sends an update message to its peers when a route is changed. If the route changes
frequently, the BGP router sends a large number of updates for the route, which can cause route flaps.
This task allows you to configure the interval for sending the same update to a peer or peer group,
avoiding frequent update sending and route flaps.
To configure the interval for sending the same update to a peer or peer group:
