This network administration project consists in the simulation of a network using GNS3 and Docker images.

The project runs on a Parrot Virtual Machine and is split in three parts:

• Basic configuration of GNS3 with a host and a router running from a Docker image.
• VXLAN network with dynamic multicast
• A datacenter-like network with BGP EVPN

• Creating a VM with ParrotOS

wget https://download.parrot.sh/parrot/iso/4.11.3/Parrot-home-4.11.3_virtual.ova

• Enabling SSH

sudo apt-get install openssh-server
systemctl enable ssh
systemctl restart ssh

• Installing our tools on our VM see config.sh

• Building our Docker images

docker build ./images/ -t host --target host
docker build ./images/ -t router --target router

The first part works as an introduction to GNS3. We need to set up a host and a router using our Docker images and we must be able to connect to both machines through the GNS3 interface.

Run gns3 P1/P1.gns3project in order to start the simulation.

VXLAN (Virtual Extensible LAN) is a network virtualization technology that solves the VLAN 4K addresses limitation.

Run gns3 P2/P2.gns3project in order to start the simulation.

Run gns3 P3/P3.gns3project in order to start the simulation.
