Hey Taqdir, There is a process called NonStop Forwarding (NSF) it's a way to continue forwarding packets while the control plane is recovering from a failure. Graceful Restart (GR) is a way to rebuild forwarding information in routing protocols when the control plane has recovered from a failure.
The fundamental premise of NSF/GR is to route through temporary failures, rather than around them. eigrp nsf <--- enables graceful restart (and is not supported in all platforms) show ip protocols verifies graceful restart is operational If I'm wrong please correct me.
