The RIP invalid timer value defines the time interval, in seconds, during which a route will remain active 
in the Routing Information Base (RIB) before it is moved to the invalid state. This timer value must be at 
least three times the update interval value.

Use the 

 command to configure the time interval that must elapse before an active 

route becomes invalid. Enter the command and the invalid timer value, in seconds. For example, to set an 
invalid interval value of 270 seconds you would enter:

-> ip rip invalid-timer 270

The invalid timer range is 3 to 360. The default is 180.

The RIP garbage timer defines the time interval, in seconds, that must elapse before an expired route is 
removed from the RIB.

Note that during the garbage interval, the router advertises the route with a metric of INFINITY.

Use the 

 command to configure the

 

time interval after which an expired route is 

removed from the RIB

. 

Enter the command and the garbage timer value, in seconds. For example, to set a 

garbage timer value of 180 seconds you would enter:

-> ip rip garbage-timer 180

The garbage timer range is 0 to 180. The default is 120.

The RIP hold-down timer defines the time interval, in seconds, during which a route remains in the hold-
down state.

Whenever RIP detects a route with a higher metric than the route in the RIB, the route with the higher 
metric goes into the hold-down state. The route updates with a metric of INFINITY are excluded.

Use the 

 command to configure the interval during which a RIP route remains in 

the hold-down state

. 

Enter the command and the hold-down timer value, in seconds. For example, to set a 

hold-down timer value of 10 seconds you would enter:

-> ip rip holddown-timer 10

The hold-down timer range is 0 to 120. The default is 0.

To optimize system performance, you can reduce the frequency of the RIP routing updates by increasing 
the length of the update, invalid, and garbage timers by about 50% above their default values. For exam-
ple:

-> ip rip update-interval 45

-> ip rip invalid-timer 270

-> ip rip garbage-timer 180
