Parameters
seconds: Specifies the T1 timer in the range of 3 to 10 seconds.
count: Specifies the number of times that the T1 timer can expire, in the range of 1 to 20.
Usage guidelines
The T1 timer specifies the number of times that GR restarter can send a Restart TLV with the RR bit set.
After restart, the GR restarter sends a Restart TLV with the RR bit set to its neighbor. If the restarting router
receives a Restart TLV with the RA set from its neighbor before the T1 timer expires, the GR process starts.
Otherwise, the GR process fails.
Examples
# Configure the T1 timer of IS-IS process 1 as 5 seconds, and the expiration times as 5.
