Net::Packet::PPPoE - PPP-over-Ethernet layer 3 object

   # Build a layer
   my $layer = Net::Packet::PPPoE->new(
      version       => 1,

This modules implements the encoding and decoding of the PPP-over-Ethernet layer.

See also Net::Packet::Layer and Net::Packet::Layer3 for other attributes and methods.

version - 4 bits

code - 4 bits

type - 8 bits

sessionId - 16 bits

payloadLength - 16 bits

pppProtocol - 16 bits

For this last attribute, we can note that it is included in the computation of payloadLength.

new

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

version: 1

type: 1

code: 0

sessionId: 1

payloadLength: 0

pppProtocol: NP_PPPoE_PPP_PROTOCOL_IPv4

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.

Load them: use Net::Packet::Consts qw(:pppoe);

NP_PPPoE_HDR_LEN

PPPoE header length.

NP_PPPoE_PPP_PROTOCOL_IPv4

NP_PPPoE_PPP_PROTOCOL_PPPLCP

Various supported encapsulated PPP protocols.
