Commands

Get cEOS

ardl get eos --image-type cEOS --version 4.31.0F --import-docker

eos-downloader configuration is availble in this repo

Start Topology

sudo containerlab deploy --reconfigure

To start topology with a specific version:

EOS_VERSION=<your eos version>; sudo containerlab deploy --reconfigure

Start a subset of the topology

Makefile gives options to start only few routers to run a subset of the backbone and limit host resources.
