NAME

Net::Frame::Layer::OSPF - Open Shortest Path First layer object

SYNOPSIS

use Net::Packet::Consts qw(:ospf);
require Net::Packet::OSPF;

# Build a layer
my $layer = Net::Frame::Layer::OSPF->new(
   version  => 2,
   type     => 0,
   length   => NF_OSPF_HDR_LEN,
   routerId => '127.0.0.1',
   areaId   => '127.0.0.1',
   checksum => 0,
   authType => NF_OSPF_AUTH_TYPE_NULL,
   authData => "0000000000000000",
);
$layer->pack;

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

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

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