NAME

Net::Packet::PPP - Point-to-Point Protocol layer 2 object

SYNOPSIS

   use Net::Packet::Consts qw(:ppp);
   require Net::Packet::PPP;
   # Build a layer
   my $layer = Net::Packet::PPP->new(
      protocol => NP_PPP_PROTOCOL_IPv4,
   );
   $layer->pack;
   print 'RAW: '.unpack('H*', $layer->raw)."\n";
   # Read a raw layer
   my $layer = Net::Packet::PPP->new(raw => $raw);
   print $layer->print."\n";
   print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n"
      if $layer->payload;
