A Mininet/Vagrant Sandbox for SRv6 and Testing

SRv6 Sandbox

This project is a SRv6 Sandbox base on Mininet.

Requirements

• Linux Kernel higher than 4.15

• Latest Mininet Installed

• Quagga Installed

• Python Installed

Install Guide

The install guide is base on Ubuntu 18.04 LTS version

1. Upgrade Kernel to the recommended version

   apt-get install linux-headers-4.15.0-38 linux-headers-4.15.0-38-generic linux-image-4.15.0-38-generic linux-modules-4.15.0-38-generic linux-modules-extra-4.15.0-38-generic

2. Reboot and check if the kernel is upgraded

   uname -a
   Linux ubuntu 4.15.0-38-generic #41-Ubuntu SMP Wed Oct 10 10:59:38 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
   

3. Install Mininet and Quagga

   apt-get install mininet gawk libreadline-dev libc-ares-dev
   wget https://github.com/Quagga/quagga/releases/download/quagga-1.2.4/quagga-1.2.4.tar.gz
   tar -xzvf ./quagga-1.2.4.tar.gz
   cd ./quagga-1.2.4
   ./configure --enable-vtysh --enable-user=root --enable-group=root --enable-vty-group=root
   make install

4. Install iproute2

   wget https://mirrors.edge.kernel.org/pub/linux/utils/net/iproute2/iproute2-4.9.0.tar.gz
   tar -xzvf ./iproute2-4.9.0.tar.gz
   cd ./iproute2-4.9.0
   apt-get install bison flex
   make
   make install

5. Install python dependencies

   pip install mako ipaddress ipmininet --no-deps

6. Run Environment

   sudo python topo.py

Usage Guide

In file topo.py:

You can define topology by adding Host/Router and adding Links.

Use build_dx4_tunnel to build a DX4 Tunnel Use build_dx6_tunnel to build a DX6 Tunnel Use RouterConfiguration to Initialize a Router to SRv6 Router.

For manual configuration

For manual configuration, run dx4_r1.sh on R1 and dx4_r3 on R3

Mininet Simple tutorial

After running sudo python topo.py, you will be promoted to a Mininet shell.

Run "xterm " to go to the destinated host shell

For example, xterm R1 will give you access to R1 shell.

srv6_sandbox's Issues

Quagga failed

Part2: install the Quagga, the project's web site is 404

pip error

Hi！
when l run pip install ipmininet --no-deps, it always makes mistakes.

I changed the pip source, but it still didn't work.
Could you help me?

SRv6对IPv4主机做 over IPv6 VPN

你好，我在运行你的代码（./topo.py ）时发现主机a 发出 ICMP ping 主机b时，由于R1配了 ip route add 10.0.2.0/24 encap seg6 mode encap segs fc00:3::bb,fc00:4::bb dev r1-eth1 这条命令，会将原有 ICMP 包封装到新的IPv6+SRH报文中，但是现在的报文顺序是IPV6/ICMPv6/IPv6+SRH/IPv4/ICMP（本应该是IPv6+SRH/IPv4/ICMP），请问下为啥这里会出现 ICMPv6 的封装头呢？我自己在 Mininet 上验证也出现了这个问题。

Vagrant failed

I counter errors during the running of "vagrant up" in multiple platforms (Mac OS, win10, win11), so I guess this may comes from the version of Virtual Box that I used (latest version in this issues posted).

Could you please update your sandbox to the new version?

Thanks!

ping: connect: Network is unreachable

After completing the relevant configuration, the result of a host ping the b host is unreachable
