Tried to picturize the router as I know, at least the Juniper router with control and forwarding plane traffic.

I have also highlighted the traffic flow and try to show which traffic is known as transit and host traffic.

Picture shows one control plane or in Juniper terms its Routing-Engine(RE) and two forwarding plane or card or FPCs.

Router as I know

Few acronyms used in picture:

  • cchip: Center chip or buffer chip
  • LUKP: Lookup chip
  • RtNH: Route Next-hop database or memory
  • CPU: It is a processor on FPC
  • intf: Interfaces
