Parameters
UPDATE Specifies the routing table update timer in seconds. The
default value is 30 seconds. Choose a value between 5 and
2,147,483,647.
TIMEOUT Specifies the routing information timeout timer in seconds.
The default value is 180 seconds. After this interval has
elapsed and no updates for a route are received by the
software, the route is declared invalid. However, it is not
removed from the routing table. Choose a value between 5
and 2,147,483,647.
GARBAGE Specifies the routing garbage collection timer in seconds.
The default value is 120 seconds. After this interval has
elapsed, the route is removed from the routing table.
Choose a value between 5 and 2,147,483,647.
Description
Use the TIMERS BASIC command to adjust basic routing protocol update
timers. This command adjusts the RIP timing parameters. Every 30
seconds, the AT-S83 software sends an update that contains the
complete routing table to every neighboring router. When the time
specified by the TIMEOUT parameter expires, the route is no longer valid.
However, a route is retained in the routing table for a short time so that
neighboring routers are notified that the route has been dropped. When
the time specified by the GARBAGE parameter expires, the route is
removed from the routing table.
Note
The route is included in all updates sent by the router until the time
specified by the GARBAGE parameter expires.
All routers in the network must have the same timers defined to allow RIP
to execute a distributed and asynchronous routing algorithm. The timers
should not be synchronized as this may lead to unnecessary collisions on
the network.
