Configures the forced hold-down timer value, in seconds, that defines an amount of time during which 
routing information regarding better paths is suppressed. A route enters into a forced hold-down state 
when an update packet is received that indicates the route is unreachable and when this timer is set to a 
non-zero value. After this timer has expired and if the value is less than 120 seconds, the route enters a 
hold-down state for the rest of the period until the remainder of the 120 seconds has also expired. During 
this time the switch will accept any advertisements for better paths that are received.

ip rip force-holddowntimer seconds

The forced hold-down time interval, in seconds. The valid range is
 0–120.

• The forced hold-down timer is not the same as the RIP hold-down timer. The forced hold-down timer 

defines a separate interval that overlaps the hold-down state. During the forced hold-down timer inter-
val, the switch will not accept better routes from other gateways.

• The forced hold-down time interval can become a subset of the hold-down timer (120 seconds) by 

using this command to set a value less than 120.

• To allow the routing switch to use better routes advertised during the entire hold-down time period, 

leave the forced hold-down timer set to the default value of 0.

-> ip rip force-holddowntimer 10
