From a Network World article:

Using BGP graceful restart, the data-forwarding plane of a router can continue to process and forward packets even if the control plane - which is responsible for determining best paths - fails.

Graceful restart also reduces routing flaps, which stabilizes the network and reduces the consumption of control-plane resources.

Graceful Restart (GR) is a way to rebuild forwarding information in routing protocols when the control plane has recovered from a failure.
