Setting RIP timers
You can set basic update timers for the RIP protocol. The protocol must be enabled in order to set the timers. The timers command
species how often RIP update messages are sent.
To set the timers, enter the following commands.
device(config) router rip
device(config-rip-router)# timer 30 180 180 120
Syntax: [no] timers update-timer timeout-timer hold-down-timer garbage-collection-timer
The update-timer parameter sets the amount of time between RIP routing updates. The possible value ranges from 3 - 21845. The
default is 30 seconds.
The timeout-timer parameter sets the amount of time after which a route is considered unreachable. The possible value ranges from 9 -
65535. The default is 180 seconds.
The hold-down-timer parameter sets the amount of time during which information about other paths is ignored. The possible value
ranges from 0 - 65535. The default is 180 seconds.
The garbage-collection-timer sets the amount of time after which a route is removed from the rip routing table. The possible value
ranges from 0 - 65535. The default is 120 seconds.

lter information
Field. Deinition
RIP Summary area Shows the current conguration of RIP on the device.
Static metric Shows the static metric conguration. ".not dened" means the route map
has not been distributed.
OSPF metric Shows what OSPF route map has been applied.
Neighbor Filter Table area
Index The lter number. You assign this number when you congure the lter.
