The PPP frame includes an 8-byte header and 2-byte trailer, which gives a total of 10 bytes. However, the FCS (Frame Check Sequence) field in the trailer can be either 2 or 4 bytes in size, depending on the negotiated PPP options. Therefore, the size of the header and trailer can vary between 8 and 10 bytes. The other options (priority, FEC, and encryption) do not influence the size of the PPP header and trailer.
