Which statement is true about the forwarding plane?

The forwarding plane, typically embodied by the Packet Forwarding Engine (PFE), uses ASICs (Application-Specific Integrated Circuits) or other specialized hardware to achieve high-speed, line-rate packet forwarding performance. ASICs are specifically designed for rapid, parallel processing of data packets efficiently.

The Routing Engine (RE) is considered the 'intelligence' of the platform, as it handles routing decisions, protocol processing, and system management, while the forwarding plane executes those decisions.

The Routing Engine (RE) maintains the primary routing tables, then compiles and sends a copy of the forwarding table (derived from the routing tables) to the forwarding plane.

While the Routing Engine (RE) might be based on an x86 architecture, the forwarding plane primarily relies on specialized ASICs, not general-purpose x86 processors, for its core packet forwarding tasks.
