For M Series routers, the Packet Forwarding Engine is implemented in ASICs that are
located on the System Control Board (SCB): a Forwarding Engine Board (FEB) (M5/M10
router), System and Switch Board (SSB) (M20 router), SCB (M40 router), or Switching
and Forwarding Module (SFM) (M40e and M160 routers). It uses a centralized route
lookup engine and shared memory. For T Series routers, the Packet Forwarding Engine
