NAME

Net::Packet::PPPLCP - PPP Link Control Protocol layer 4 object

SYNOPSIS

use Net::Packet::Consts qw(:ppplcp);
require Net::Packet::PPPLCP;

# Build a layer
my $layer = Net::Packet::PPPLCP->new(
   code        => NP_PPPLCP_CODE_ECHO_REQUEST,
   identifier  => 1,
   length      => NP_PPPLCP_HDR_LEN,
   magicNumber => 0xffffffff,
);
$layer->pack;

print 'RAW: '.unpack('H*', $layer->raw)."\n";

# Read a raw layer
my $layer = Net::Packet::PPPLCP->new(raw => $raw);

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