120 seconds.

Usage Guide Adjusting the above clocks may speed up routing protocol convergence and fault recovery. Devices
connected to the same network must have consistent RIP clock values. Adjustment of RIP clocks is
not recommended unless otherwise specified.
To check the current RIP clock parameters, use the show ip rip command.
If you set the clock to a small value on low-speed links, some risks will be caused because
numerous update packets may use up the bandwidth. In general, the clocks can be configured
with smaller values on Ethernet or the lines of above 2 Mbit/s to reduce the convergence time of
routes.
Configuration The following example enables the RIP update packets that are sent every 10 seconds. If no update
Examples packet is received within 30 seconds, related routes become invalid and enter the invalid status.
When another 90s elapses, they will be cleared.
Ruijie (config)# router rip
Ruijie (config-router)# timers basic 10 30 90

Indicates the route update time in seconds. The update keyword
defines the period at which the device sends route update packets.
Each time an update packet is received, the "Invalid" and "Flush"
clocks are reset. By default, a route update packet is sent every 30
seconds.
Indicates the route invalid time in seconds, starting from the last valid
update packet. The "invalid" defines the period when the route in the
routing table becomes invalid due to no update. The invalid period of
route shall be at least three times the route update period. If no
update packet is received within the route invalid period, the related
route becomes invalid and enters into the "invalid" state. If an update
packet is received within the period, the clock resets. By default, the
Invalid time is 180 seconds.
Indicates the route flushing time in seconds, starting when a RIP
route enters into the invalid status. When the flush time is due, the
routes in the invalid status will be cleared out of the routing table. The
default Flush time is 120 seconds.
