R3721-F3210-F3171-HP High-End Firewalls Network Management Command Reference-6PW101

833
The timers configured with the peer timer command are preferred to the timers configured with the timer
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 IPv6 BGP peers, but they become valid for an IPv6 BGP peer only after
the relevant IPv6 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.
