A. NSR delivers TCP/UDP stream status reducing control plane stress for other networking devices through concatenated announcements from the routing protocol process (rpd)

B. NSR accounts for large and small traffic flows to ensure coherent forwarding path selection during failover.

C. NSR saves routing protocol information by running the routing protocol process (rpd) on the backup Routing Engine.

D. NSR is self-contained and does not rely on helper routers (or switches) to assist the routing platform in restoring routing protocol information.
