The IS-IS view is displayed.
Step 3 Run:
graceful-restart interval interval-value
The interval for reestablishing an IS-IS GR session is set.
The restart interval is set to the Holdtime in an IS-IS Hello PDU. Thus, the adjacency relationship
is not torn down when the switch restarts. By default, the restart period is 300 seconds.
Step 4 (Optional) Run:
graceful-restart suppress-sa
The GR restarter is configured to suppress the Suppress-Advertisement (SA) bit of the restart
TLV.
To prevent a switch from suppressing the SA bit in a Hello PDU during the active/standby
switchover, the administrator can run the undo graceful-restart suppress-sa command.
By default, the SA bit is not suppressed.
