Command Reference RIPng Commands
4.15 timers
Use this command to adjust the RIPng timer. Use the no form of this command to restore the default
settings.
timers update invalid flush
Sets the routing update time, in seconds. The update parameter
defines the period of sending the routing update packets by the
device. The invalid and flush parameter reset once the update
packets are received.
Sets the routing invalid time, in seconds, starting from receiving the
last valid update packet. The invalid parameter defines the invalid
time for the un-updated routing in the routing list. The routing invalid
time shall be three times larger than the routing update time. The
routing will be invalid if no update packets are received within the
routing invalid time, and it will reset if the update packets are received
within the invalid time.
Sets the routing flush time, in seconds, starting from RIPng entering
to invalid state. The invalid routing will be removed from the routing
list if the flush time expires.
The default update time is 30 seconds; the default invalid time is 180 seconds; and the default flush
time is 120 seconds.
Routing process configuration mode.
Adjusting the above time may speed up the RIPng convergence time and the troubleshooting time.
The RIPng time must be consistent for the devices connecting to the same network. You are not
recommended to adjust the RIP time, except for the specific requirement.
Use the show ipv6 rip command to view the current RIPng time parameter setting.
In the low-speed link, with the short time configured, large amount of the update packets consumes a
lot of bandwidth. Generally, the short time can be configured in the Ethernet or 2Mbps-higher line to
shorten the convergence time of the network routing.
The following example shows how to send the RIP update packets every 10 seconds. The routing will
be invalid if no update packets are received within 30 seconds, and the routing will be removed after
being invalid for 90 seconds.
Ruijie(config)# ipv6 router rip
Ruijie(config-router)# timers 10 30 90
