Command
Timers
Use
Changes the RIP timers associated with RIP on the router.
Syntax
Router(config-router)#timers basic <update interval> <invalid> <holddown> <flush> <sleep time>
Options
| <update interval> | Time between route updates |
| <invalid> | Time interval that determines that a route is down |
| <holddown> | Route is no longer used but is still held in routing table |
| <flush> | How long until route is removed from routing table |
| <sleep time> | The time between rip packets |
Example
For this example, rip timers are set on R1, R2, and R3 using the below commands.
|
R1#conf t |
|
R2#conf t |
|
R3#conf t |
To simulate what happens when a rip route is lost, int fa0/0 on R1 is shut down.
|
R1(config-router)#int fa0/0 |
Now, after 41 seconds of R1 being down, the rip route is still active on R2.
|
R2(config-if)#do show ip route rip |
45 seconds after shutting down R1’s int fa0/0, the status of the routes is set to “possibly down”.
|
R2(config)#do show ip route rip |
90 seconds after, the route is lost.
|
R2(config)#do show ip route rip |
