Configuring Logical System Graceful Restart

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 enable graceful restart in a logical system, include the graceful-restart statement at the [edit logical-systems logical-system-name routing-options] hierarchy level. To configure a global 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.

[edit]
logical-systems {logical-system-name {routing-options {graceful-restart {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.

Configuring Graceful Restart for a Routing Instance

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].

[edit]
logical-systems {logical-system-name {routing-instances {instance-name {routing-options {graceful-restart {disable;restart-duration seconds;}}}}}}

To disable graceful restart for individual protocols with the disable statement at the [edit logical-systems logical-system-name routing-instances instance-name protocols protocol-name graceful-restart] hierarchy level.
