Cumulus 5.x EVPN VXLAN BGP fabric
| Description | Cumulus Linux VX with leaf and spine topology |
| Components | Cumulus Linux |
| Resource requirements1 | 4 5 GB |
| Topology file | topo.clab.yml |
| Name | cvx05 |
| Version information2 | cvx:5.3.0 Docker version 25.0.3, build 4debf41 |
Description#
The lab consists of Cumulus Linux 5.3 fabric composed of 2 borders, 2 spines and 2 leafs. The topology demonstrate a EVPN VXLAN BGP configuration. The topology is additionally equipped with a Linux container connected to leaves to facilitate use cases which require access side emulation.
Configuration#
The custom docker image need to be built locally before running the deployment
docker build \
--force-rm=true \
-t cx_ebtables:5.3.0 \
-f cx_ebtables.Dockerfile .
All 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 on their vlan interfaces:
# ping leaf interface
root@border-1:/# ping 10.162.0.14

Use cases#
- Demonstrate how a
cvxcan run with a EVPN VXLAN BGP fabric - Demonstrate Cumulus Linux Leaf and spine with NVUE configuration (introduced in version 5.X)
- Verify vlan trunking and access on connected host to a leaf
