I'm going with NSF per the below. Cisco Nonstop Forwarding (NSF), also known as graceful restart, ensures uninterrupted network traffic during routing protocol convergence after a failover or switchover. In the context of the Nexus 7700, NSF with Stateful Switchover (SSO) minimizes network downtime by allowing routing protocols to continue forwarding traffic even while their routing tables are being updated.

wtf. Cisco literally uses A, C, D interchangeably in a two paragraph explaination of HA and graceful restart. But it seems Cisco leans on the term graceful restart, so should probably be A if I HAVE to choose. https://www.cisco.com/c/en/us/td/docs/switches/datacenter/sw/4_2/nx-os/unicast/configuration/guide/l3_cli_nxos/l3_ospf.html#pgfId-1243342 "High Availability and Graceful Restart"
