  2. Rachid says:

    The PFE is the central processing component of the forwarding plane. The PFE systematically forwards traffic based on its local
    copy of the forwarding table. The PFE’s forwarding table is a synchronized copy of the information created on and provided by
    the RE. Storing and using a local copy of the forwarding table allows the PFE to forward traffic more efficiently and eliminates
    the need to consult the RE each time a packet needs to be processed. Using this local copy of the forwarding table also allows
    platforms running the Junos OS to continue forwarding traffic during control plane instabilities.
