IP Routing Lab

This IP Routing lab consists of 3 ASes where each AS has 3 routers and 2 clients using FRR docker image. Please refer to the topology when you are going to configure each router.

Prerequisite

To build this IP routing lab, you need to install Docker Desktop for Mac or Windows

Clone Repo & Run docker-compose

• Prepare a directory where you will clone this repo and do git clone https://github.com/abazh/routing_lab.git !!!Warning: if you are using WSL2, please clone or extract the files in the Linux file system directory: \\wsl$\ and run everything from wsl !!!
• Go to directory of the cloned repo
• Run docker-compose up -d

This docker-compose command will generate all docker containers (6 clients and 9 routers) To stop or start the containers

• Run docker-compose stop or docker-compose start

Remember, you need to reset gateway on each client and each router everytime after docker-compose up -d or docker-compose start. You can refer to the commands in route_clean.sh or route_clean.ps1 script

• Run the script route_clean.sh or route_clean.ps1 (windows powershell)

Configure Routers:

You can refer to the Wiki of this repository on how to configure each router.

There are 3 IGP routers, each with ASN 100, 200, and 300: To access each router configuration console, you need to run a command in your PowerShell console or terminal console:

• docker exec -it R1 vtysh

To test routing between clients, you can do traceroute from each client

• docker exec -it C1 traceroute -n C10

your result may look like:

• traceroute to C10 (10.10.10.2), 30 hops max, 46 byte packets
• 1 10.10.1.254 0.040 ms 0.033 ms 0.321 ms
