H3C S5820X Series Command Reference Manual page 311

timeout-value: Interval of the timeout timer in seconds, in the range of 1 to 86400.
update-value: Interval of the update timer in seconds, in the range of 1 to 86400.
Description
Use the timers command to configure RIPng timers.
Use the undo timers command to restore the default.
By default, the garbage-collect timer is 120 seconds, the suppress timer 120 seconds, the timeout timer
180 seconds, and the update timer 30 seconds.
RIPng is controlled by the four timers.
The update timer defines the interval between update messages.
•
The timeout timer defines the route aging time. If no update message related to a route is received
•
within the aging time, the metric of the route is set to 16 in the routing table.
The suppress timer defines for how long a RIPng route stays in the suppressed state. When the metric
•
of a route is 16, the route enters the suppressed state. In the suppressed state, only routes which
come from the same neighbor and whose metric is less than 16 will be received by the router to
replace unreachable routes.
• The garbage-collect timer defines the interval from when the metric of a route becomes 16 to when
it is deleted from the routing table. During the garbage-collect timer length, RIPng advertises the
route with the routing metric set to 16. If no update message is announced for that route before the
garbage-collect timer expires, the route will be completely deleted from the routing table.
NOTE:
H3C does not recommend to change the default values of these timers under normal circumstances.
•
• The lengths of these timers must be kept consistent on all routers in the network.
Examples
# Configure the update, timeout, suppress, and garbage-collect timers as 5s, 15s, 15s and 30s.
