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:
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].
