Use this command to restart SNMP in Routing Information Protocol (RIP)
Command Syntax
snmp restart rip

timers basic
Use this command to adjust routing network timers.
This command adjusts the RIP timing parameters. Every 30 seconds, an update is sent out containing the complete routing table to every neighboring router. When the time specified by the timeout parameter expires, the route is no longer valid. However, it is retained in the routing table for a short time so that neighbors are notified that the route has been dropped. When the time specified by the garbage parameter expires, the route is finally removed from the routing table. Until the garbage time expires, the route is included in all updates sent by the router.
All routers in the network must have the same timers to allow RIP to execute a distributed and asynchronous routing algorithms. The timers should not be synchronized as it might lead to unnecessary collisions on the network.
Use the no parameter with this command to restore the default routing network timers.
Command Syntax
timers basic <5-2147483647> <5-2147483647> <5-2147483647>
no timers basic
Parameters
<5-2147483647>
Specify the routing table update timer in seconds. The default is 30 seconds.
<5-2147483647>
Specify the routing information timeout timer in seconds. The default is 180 seconds. After this interval has elapsed and no updates for a route are received, the route is declared invalid.
<5-2147483647>
Specify the routing garbage collection timer in seconds. The default is 120 seconds.
Default
The default routing table update time is 30 seconds.
The default routing information timeout time is 180 seconds.
The default routing garbage collection time is 120 seconds.
Command Mode
Router mode
Applicability
This command was introduced before OcNOS version 1.3.
Examples
#configure terminal
(config)#router rip
(config-router)#timers basic 30 180 120
 
(config)#router rip
(config-router)#no timers basic
version
Use this command to specify a RIP version used globally by the router. RIP can be run in version 1 as well as version 2 mode. Version 2 has more features than version 1 including authentication. Once the rip version is set, rip packets of that version will be received and sent on all the rip-enabled interfaces.
Use the no parameter with this command to restore the default version.
Note: The ip rip receive version command and the ip rip send version command override the value set by the version command.
Command Syntax
version <1-2>
no version
Parameters
<1-2>
Specify the version of RIP processing.
Default
Version 2
Command Mode
Router mode
Applicability
This command was introduced before OcNOS version 1.3.
