For Layer 3 VPNs only, you must also configure graceful restart globally for a routing
instance inside a logical system. To configure, include the
the [edit logical-systems logical-system-name routing-instances instance-name
hierarchy level. Because you can configure multi-instance BGP and
routing-options]
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
statement at the
restart-duration
routing-instances instance-name routing-options]

logical-system-name {

This enables graceful restart globally for all routing protocols. You can, optionally, modify
or supplement the global settings at the individual protocol level.
