Cumulus Linux and FRR

Description Cumulus Linux connected back-to-back with FRR
Components Cumulus Linux
Resource requirements[^1] 1
1 GB
Topology file topo.clab.yml
Name cvx01
Version information[^2] cvx:4.3.0 docker-ce:19.03.13


The lab consists of Cumulus Linux and FRR nodes connected back-to-back over a point-to-point ethernet link. Both nodes are also connected to the clab docker network over their management eth0 interfaces.


Both nodes have been provided with a startup configuration and should come up with all their interfaces fully configured.

Once the lab is started, the nodes will be able to ping each other:

$ ssh lab-cvx01-sw1

Use cases#

  • Demonstrate how a cvx node, running in its default ignite runtime, can connect to nodes running in other runtimes, e.g. docker
  • Demonstrate how to inject startup configuration into a cvx node.
  • Verify basic control plane and data plane operations
