Preference (Ipv6 Address Family View/Ipv6 Bgp-Vpn Instance View) - H3C S5820X Series Command Reference Manual

Description
Use the peer timer command to configure keepalive interval and holdtime interval for a peer or peer
group.
Use the undo peer timer command to restore the default.
keepalive interval defaults to 60 seconds, and holdtime interval defaults to 180 seconds
The timers configured with this 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.
After this command is executed, the peer connection is closed at once, and a new connection to the peer
is negotiated using the configured hold time.
Related commands: timer.
