Graceful restart allows a router whose VPN control plane is undergoing a restart to
continue to forward traffic while recovering its state from neighboring routers. Without
graceful restart, a control plane restart disrupts any VPN services provided by the router.
Graceful restart is supported on Layer 2 VPNs, Layer 3 VPNs, virtual-router routing
instances, and VPLS.
To implement graceful restart for a Layer 2 VPN or Layer 3 VPN, perform the configuration
tasks described in the following sections:
Configuring Graceful Restart Globally on page 85
Configuring Graceful Restart for the Routing Instance on page 85
To enable graceful restart, include the
hierarchy level. To configure a global duration for the graceful restart

period, include the restart-duration
hierarchy level.

To disable graceful restart globally, include the
routing-options graceful-restart]
For Layer 3 VPNs only, you must also configure graceful restart for all routing and
MPLS-related protocols within a routing instance by including the
statement at the
[edit routing-instances instance-name routing-options]
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
routing-instances instance-name routing-options]
