This is a repo of containerlab topologies for labbing. Currently these labs operate with cEOS-lab, which is Arista's containerized version of their EOS network operating system (NOS). As it's a container, it doesn't have all the features of a physical system (like hardware queues), but most features are supported, including data plane, control plane, EVPN/VXLAN, MPLS, and more. cEOS-lab is free to use for lab purposes, and is easy to obtain, which is why it's used for these topologies.
This topolgy is two spines, four leafs, two 'hosts' and one router connected to two of the leafs. This is total of nine containers, and is tested for 16 GB VMs with 8vCPUs.
The plan is to have other sizes, such as a smaller size (8 GB/4 vCPUs) and a large size (32GB/12vCPUs).
This topology is sufficient to run a three-stage Clos EVPN/VXLAN network, or a standard Layer 2 collapsed core (Arista calls is Layer 2 leaf/spine).
In a directory clone this repo:
git clone https://github.com/tonybourke/NERD_clab_topologies
First, make sure you have Docker installed (this guide was based on the Autobox).
Change to the directory, like clos-medium, and run the containerlab deploy command.
sudo containerlab deploy
You should see all the containers started. It may take a minute or two.
