A scapy clone, with support for additional packet headers
THIS REPOSITORY IS DEPRECATED AND IS NO LONGER MAINTAINED. P4LANG SOFTWARE NOW USES UPSTREAM SCAPY, WHICH SUPPORTS VXLAN, GENEVE, ETC.
Barefoot modified scapy, which supports VXLAN. Waiting for VXLAN support to be added to the main scapy repo. This modified repo now also supports a ERSPAN-like header.
To install: sudo python setup.py install
To check that the modifications work, open a scapy CLI (just type 'scapy' in a terminal) and type the following:
Welcome to Scapy (2.2.0-dev)
load_contrib('vxlan') Ether()/IP()/UDP()/VXLAN()/Ether()/IP()/TCP() <Ether type=0x800 |<IP frag=0 proto=udp |<UDP dport=4789 |<VXLAN |<Ether type=0x800 |<IP frag=0 proto=tcp |<TCP |>>>>>>> load_contrib('erspan') Ether()/IP()/GRE()/ERSPAN()/Ether()/IP()/TCP() <Ether type=0x800 |<IP frag=0 proto=gre |<GRE proto=0x22eb |<ERSPAN |<Ether type=0x800 |<IP frag=0 proto=tcp |<TCP |>>>>>>>
Note how the UDP dport and the GRE proto number are updated automatically.
