segway's Introduction

segway - Testing framework for IPv6 segment routing on Linux

segway sets up a network namespace with special network interfaces, simulating an IPv6 network with Segment Routing, and executes a given test suite, sending and sniffing packets. An example of test suite is provided in tests/example.seg.

segway uses Python 2.7 and requires several dependencies, which can be installed using pipenv.

git clone https://github.com/Zashas/segway.git
pipenv install
pipenv shell
cd segway
sudo python segway.py tests/example.seg

Usage

Usage:
    segway.py <path_to_tests> [--ns=<ns_name>] [-k] [-r] [-p]
    segway.py (-h | --help)

Options:
    -h, --help  Show help
    --ns=<ns_name>  Use specific network space name
    -k              Keep network namespace after running tests
    -r              Reuse network namespace and interfaces

segway's Issues

Cannot match packets with wide-used TCP/UDP ports

Incorrect packet received instead of packet #7.
	Sent :     fc00::2 -> fd00::42 / [fc00::1,+fd00::42] <sl 1,le 1> / UDP(4880,53) / "foobar"
	Expected : fc00::2 -> fc00::1 / [+fc00::1,fd00::42] <sl 0,le 1> / UDP(4880,53) / "foobar"
	Received : fc00::2 -> fc00::1 / [+fc00::1,fd00::42] <sl 0,le 1> / UDP(4880,53) / DNS
