3. Enable IS-IS GR.
graceful-restart
By default, the GR capability for IS-IS is
disabled.
4. (Optional.) Suppress
the SA bit during
restart.
graceful-restart suppress-sa
By default, the SA bit is not suppressed.
By enabling the GR restarter to suppress
the Suppress-Advertisement (SA) bit in the
hello PDUs, the neighbors will still
advertise their adjacency with the GR
restarter.

By default, the T2 timer is 300 seconds.
Configuring IS-IS NSR
After an active/standby switchover, the GR restarter obtains routing information from its neighbors,
and the IS-IS process must learn all the routes. If the network topology changes during the
switchover, removed routes cannot be updated to the device, which can result in blackhole routes.
NSR solves the problem by backing up IS-IS link state information from the active process to the
standby process. After an active/standby switchover, NSR can complete link state recovery and
route regeneration without requiring the cooperation of other devices.
IMPORTANT:
IS-IS NSR and IS-IS GR are mutually exclusive. Do not configure them at the same time.
To configure IS-IS NSR:

3. Enable IS-IS NSR.
non-stop-routing
By default, IS-IS NSR is disabled.
IS-IS NSR takes effect on a per-process
basis. As a best practice, enable NSR for
each IS-IS process.
Configuring BFD for IS-IS
BFD provides a single mechanism to quickly detect and monitor the connectivity of links between
IS-IS neighbors, reducing network convergence time. For more information about BFD, see High
Availability Configuration Guide.
