HP 6125G Command Reference Manual page 216

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.
Related commands: peer timer.
