Use to specify the maximum amount of time, in seconds, that a restarting router waits
for the LSP database to synchronize.
You must configure independent instances of the T2 timer for each IS-IS level at which
the router operates. This requirement means that for a level 1-2 router, you must issue
this command twice: first to configure the timer for level 1, and a second time to
configure it for level 2.
Use either the level-1 keyword to set the T2 wait time for level 1 routing, or the level-2
keyword to set the wait time for level 2 routing.
You can specify a value in the range 5–120 seconds for each level.
Example—Configures the T2 wait time for a level 1-2 IS-IS router
host1(config-router)#nsf t2 level-1 70
host1(config-router)#nsf t2 level-2 50
Use the no version to restore the default T2 wait time, 100 seconds.
See nsf t2
Use to specify the maximum amount of time, in seconds, that the restarting router
waits before setting the overload bit.
The restarting router sets the overload bit to indicate that the LSP database has not
been synchronized and the IS-IS graceful restart operation has failed.
You must use one of the following methods to set the T3 wait time:
Use the manual keyword and a value in the range 5–120 seconds to set the T3 wait
time manually.
Use the adjacency keyword to specify that the restarting router should obtain its T3
wait time from neighboring IS-IS routers that have active adjacencies to this router.
This option sets the wait time to the minimum of the remaining times specified in
the restart TLVs contained in the hello packets that the router receives from its
neighbors.
Example1
host1(config-router)#nsf t3 manual 120
Example 2
host1(config-router)#nsf t3 adjacency
Use the no version to restore the default T3 wait time, 100 seconds.
See nsf t3
host1(config)#router isis floor12
host1(config-router)#net 47.0010.0000.0000.0000.0001.0001.1111.1111.1111.00
host1(config-router)#exit
host1(config)#interface atm 0/1
