Containerlab Notes

Example Topology

In order to start this topology, there must already be a cEOS container in the local docker registry:

$ docker import cEOS64-lab-4.31.0F.tar.tar ceos:4.31.0F
sha256:fb3d07a3dcafbdccc766bd31c4320c3ffd847cd7d774d8e6eb846917182e59a6

$ docker image ls ceos
REPOSITORY   TAG       IMAGE ID       CREATED              SIZE
ceos         4.31.0F   fb3d07a3dcaf   About a minute ago   2.42GB

test1.clab.yml:

name: test1
prefix: __lab-name
# This is the default containerlab mgmt subnets
#mgmt:
