timer (IPv6 address family view)
Use timer to specify the IPv6 BGP keepalive interval and holdtime interval.
Use undo timer to restore the default.
Syntax
timer keepalive keepalive hold holdtime
undo timer
Default
The keepalive and holdtime intervals are 60 seconds and 180 seconds, respectively.
Views
IPv6 address family view
Default command 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.
Usage guidelines
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 is sent to the peer, and the peer
connection never times 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.
