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.
• Update timer—Defines the interval between update messages.
• 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.
• Suppress timer—Defines for how long a RIPng route stays in suppressed state. When the metric of
a route is 16, the route enters the suppressed state. In 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.
• 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:
• HP does not recommend changing the default values of these timers under normal circumstances.
• The lengths of these timers must be kept consistent on all routers in the network.
