Parameters
seconds: Specifies the T2 timer in the range of 30 to 65535 seconds.
Usage guidelines
The T2 timer specifies the LSDB synchronization interval. Each LSDB has a T2 timer. The Level-1-2 router
has two T2 timers: a Level-1 timer and a Level-2 timer. If the LSDBs have not achieved synchronization
before the two timers expire, the GR process fails.
Examples
# Configure the T2 timer of IS-IS process 1 as 50 seconds.
