graceful-restart t3
{adjacency | manual
seconds}
ROUTER-ISIS Configure Graceful Restart timer T3 to set the time used by the restarting
router as an overall maximum time to wait for database synchronization
to complete.
adjacency: the restarting router receives the remaining time value from
its peer and adjusts its T3 value accordingly if user has configured
configured this option.
manual: allows you to specify a fixed value that the restarting router
should use.
Range: 50-120 seconds
Default: 30 seconds
Note: If this timer expires before the synchronization has completed, the restarting
router sends the overload bit in the LSP. The 'overload' bit is an indication to the
receiving router that database synchronization did not complete at the restarting router.
