Adjusting Timers
RIP sends routing updates at regular intervals. By default, the
Management Software transmits routing updates every 30 seconds. If the
switch does not receive a routing update from another switch for 180
seconds, it declares the route invalid. If no routing update is received after
an additional 120 seconds, the switch removes the route from the routing
table. You can adjust the timers to minimize disruptions to end users of the
network when a quick recovery is necessary.
To regulate performance, the Management Software offers three timers:
the interval at which RIP routing updates are sent, the interval after which
a route is declared invalid, and the interval after which the router is
removed from the routing table. To control timers, the TIMERS BASIC
command uses three parameters:
 update
 timeout
 garbage
Table 257 lists the parameters of the TIMERS BASIC command.
The following example sets the switch to transmit routing updates every 20
seconds, declare a route invalid after 120 seconds have passed and no
updates for the route are received, and remove the route from the routing
table after an additional 60 seconds have passed:
awplus> enable
awplus# configure terminal
awplus(config)# router rip
awplus(config-router)# timers basic 20 120 60
Table 257. TIMERS BASIC Command Parameters
To Do This Task Parameter Ranges
Specify the interval at which routing updates are
sent in seconds. The default is 30 seconds. update 5 to 2,147,483,647
seconds
Specify the routing information timeout timer in
seconds. After this interval has elapsed, and no
updates for a route are received, the route is
declared invalid. The default is 180 seconds. timeout 5 to 2,147,483,647
seconds
Specify the routing garbage-collection timer in
seconds. After this interval has elapsed, and no
updates for a route are received, the route is
removed from the routing table. The default is 120
seconds. garbage 5 to 2,147,483,647
