NAME

Net::Packet::OSPF - Open Shortest Path First layer 4 object

SYNOPSIS

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

# Build a layer
my $layer = Net::Packet::OSPF->new(
   version          => 2,
   messageType      => 0,
   length           => NP_OSPF_HDR_LEN,
   sourceOspfRouter => '127.0.0.1',
   areaId           => '127.0.0.1',
   checksum         => 0,
   authType         => NP_OSPF_AUTH_TYPE_NULL,
   authData         => '',
);
$layer->pack;

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

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

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

METHODS

new

Object constructor. You can pass attributes that will overwrite default ones. Default values:

version: 2

messageType: 0

length: NP_OSPF_HDR_LEN

sourceOspfRouter: '127.0.0.1'

areaId: '127.0.0.1'

checksum: 0

authType: NP_OSPF_AUTH_TYPE_NULL

authData: ''

pack
