Graceful restart for a logical system functions much as graceful restart does in the main router. The only difference is the location of the graceful-restart statement.
The following topics describe what to configure to implement graceful restart in a logical system:
To configure graceful restart globally in a logical system, include the graceful-restart statement at the [edit logical-systems logical-system-name routing-options] hierarchy level. To configure the duration of the graceful restart period, include the restart-duration statement at the [edit logical-systems logical-system-name routing-options graceful-restart] hierarchy level.

- disable;
- restart-duration seconds;
- }
- }
- }
- }
To disable graceful restart globally, include the disable statement at the [edit logical-systems logical-system-name routing-options graceful-restart] hierarchy level.
For Layer 3 VPNs only, you must also configure graceful restart globally for a routing instance inside a logical system. To configure, include the graceful-restart statement at the [edit logical-systems logical-system-name routing-instances instance-name routing-options] hierarchy level. Because you can configure multi-instance BGP and multi-instance LDP, graceful restart for a carrier-of-carriers scenario is supported. To configure the duration of the graceful restart period for the routing instance, include the restart-duration statement at the [edit logical-systems logical-system-name routing-instances instance-name routing-options].
