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;

messageType - 8 bits
length - 16 bits
sourceOspfRouter - 32 bits
areaId - 32 bits
checksum - 16 bits
authType - 16 bits
authData - 64 bits

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
Packs all attributes into a raw format, in order to inject to network. Returns 1 on success, undef otherwise.
unpack
Unpacks raw data from network and stores attributes into the object. Returns 1 on success, undef otherwise.
