Description
This command allows you to adjust the routing timers. All values
expect for sleeptime
are in seconds.
-
update-value
The interval at which routing updates are sent.
-
invalid-value
The interval after which a route is considered invalid if an update does not arrive.
-
holddown-value
The time that the router waits after deciding that a route is invalid before accepting further information about it. For example, if a router decides that a certain route has become invalid, it waits for the hold-down period to pass before believing any other information stating that the route is valid. This procedure helps to maintain routing stability.
-
flush-value
The interval after which invalid routes are purged from the routing table.
-
sleeptime-value
Optional. This timer’s value is the interval in milliseconds to wait after a flash update. This value should be less than the update value. Sleeptime is not applicable to RIP.
