NAME

       Net::Frame::Layer::PPP - Point-to-Point Protocol layer object

SYNOPSIS

          use Net::Frame::Layer::PPP qw(:consts);

          # Build a layer
          my $layer = Net::Frame::Layer::PPP->new(
             address  => 0xff,
             control  => 0x03,
             protocol => NF_PPP_PROTOCOL_IPv4,
          );
          $layer->pack;

          print 'RAW: '.$layer->dump."\n";

          # Read a raw layer
          my $layer = Net::Frame::Layer::PPP->new(raw => $raw);

          print $layer->print."\n";
          print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n"
             if $layer->payload;

DESCRIPTION

       This modules implements the encoding and decoding of the Point-to-Point Protocol layer.

       See also Net::Frame::Layer for other attributes and methods.

ATTRIBUTES

       address - 8 bits
       control - 8 bits
       protocol - 16 bits

       The following are inherited attributes. See Net::Frame::Layer for more information.

       raw
       payload
       nextLayer

METHODS

       new
       new (hash)
           Object constructor. You can pass attributes that will overwrite default ones. See
           SYNOPSIS for default values.

       The following are inherited methods. Some of them may be overridden in this layer, and
       some others may not be meaningful in this layer. See Net::Frame::Layer for more
       information.
