HP FlexNetwork 3600 v2 Series Command Reference Manual page 274

Default level
2: System level
Parameters
keepalive: Keepalive interval in seconds, ranging from 0 to 21845.
holdtime: Holdtime interval in seconds, whose value is 0 or in the range of 3 to 65535.
Description
Use timer to configure the BGP keepalive interval and holdtime interval.
Use undo timer to restore the default.
By default, the BGP keepalive interval and the holdtime interval are 60 seconds and 180 seconds.
The timers configured with the peer timer command are preferred to the timers configured with this
command.
If the holdtime interval is configured as 0, no keepalive message will be sent to the peer, and the peer
connection will never time out. If the keepalive interval is configured as 0 and the negotiated hold
time is not 0, one third of the hold time is taken as the interval for sending keepalive messages.
If neither the holdtime interval nor the keepalive interval is configured as 0, the holdtime interval must
be at least three times the keepalive interval.
The configured timers apply to all BGP peers, but they become valid for a BGP peer only after the
relevant BGP connection is reset.
After this command is executed, no peer connection is closed at once. The configured hold time is
used for negotiation when a peer relationship is reestablished.
