ESCRIPTION
This command is entered in the Router Configuration Mode. This command is
used to adjust routing protocol timers to tune the routing protocol performance to
better suit your internetwork needs.
You can make the timer adjustments in the following order: Update, invalid,
holddown, flush, sleeptime. All these are mandatory, except sleeptime.

Parameter
Description
Update <0-
4294967295>
Specify the interval (in seconds) between updates. This is
the fundamental timing parameter of the routing protocol.
The default is 30 seconds.
Invalid <1-
4294967295>
Interval of time (in seconds) after which a route is declared
invalid. The interval should be at least three times the value
of the update argument. A route becomes invalid when
there is an absence of updates that refresh the route. The
route then enters into a holddown state. The route is
marked inaccessible and advertised as unreachable.
However, the route is still used for forwarding packets. The
default is 180 seconds.
Holddown <0-
4294967295>
Interval (in seconds) during which routing information
regarding alternate paths is suppressed. It should be at
least three times the value of the update argument. A route
enters into a holddown state when an update packet is
received that indicates the route is unreachable. The route
is marked inaccessible and advertised as unreachable.
However, the route is still used for forwarding packets.
When holddown expires, routes advertised by other sources
are accepted and the route will no longer be inaccessible.
The default is 180 seconds.
Flush <1-
4294967295>
Amount of time (in seconds) that must pass before the route
is removed from the routing table. The interval specified
should be greater than the value of the invalid argument. If it
is less, the proper holddown interval cannot elapse, which
results in a new route being accepted before the holddown.
The default is 240 seconds.
sleep-time
<1-
4294967295>
Interval (in milliseconds) for postponing routing updates in
the event of a flash update. The sleeptime value should be
less than the update time. If the sleeptime is greater than
the update time, routing tables will become unsynchronized.
