# nsf t3

#### Syntax

[ no ] nsf t3 { manual [ seconds ] | adjacency }

#### Release Information

Command introduced before JunosE Release 7.1.0.

#### Description

Specifies the maximum amount of time, in seconds, that the restarting router waits before setting the overload bit to indicate that the LSP database has not been synchronized and the IS-IS graceful restart operation has failed. The no version restores the default T3 wait time, 30 seconds.

#### Options

- manual—Sets the T3 wait time manually to the specified number of seconds
- seconds—Maximum wait time, in the range 5–120 seconds, before the restarting router sets the overload bit; default value is 30 seconds
- adjacency—Specifies 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.
