Configuring OSPFv3 NSR
Nonstop routing (NSR) backs up OSPFv3 link state information from the active process to the standby process. After an active/standby switchover, NSR can complete link state recovery and route regeneration without tearing down adjacencies or impacting forwarding services.
NSR does not require the cooperation of neighboring devices to recover routing information, and is used more often than GR.
