RIPng is controlled by the following 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.
IMPORTANT:
•
Hewlett Packard Enterprise 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.
Examples
# Configure the update, timeout, suppress, and garbage-collect timers as 5s, 15s, 15s, and 30s.
