NAME¶
Net::Frame::Layer::IPv6::HopByHop - Internet Protocol v6 Hop-By-Hop Extension
Header layer object
SYNOPSIS¶
use Net::Frame::Simple;
use Net::Frame::Layer::IPv6::HopByHop;
my $ipv6eh = Net::Frame::Layer::IPv6::HopByHop->new(
nextHeader => NF_IPv6_PROTOCOL_TCP,
hdrExtLen => 2,
options => []
);
#
# Read a raw layer
#
my $layer = Net::Frame::Layer::IPv6::HopByHop->new(raw => $raw);
print $layer->print."\n";
print 'PAYLOAD: '.unpack('H*', $layer->payload)."\n"
if $layer->payload;
DESCRIPTION¶
This modules implements the encoding and decoding of the IPv6 Hop-By-Hop options
Extension Header layer.

- options
- A number of Net::Frame::Layer::IPv6::Option objects.
The following are inherited attributes. See
Net::Frame::Layer for more
