Description Connecting nodes via linux bridges
Components Nokia SR Linux
Resource requirements1 2

Topology file br01.clab.yml
Name br01


This lab consists of three Nokia SR Linux nodes connected to a linux bridge.


containerlab will not create/remove the bridge interface on your behalf.

bridge element must be part of the lab nodes. Consult with the topology file to see how to reference a bridge.

Use cases#

By introducing a link of bridge type to the containerlab topology, we are opening ourselves to some additional scenarios:

  • interconnect nodes via a broadcast domain
  • connect multiple fabrics together
  • connect containerlab nodes to the applications/nodes running outside of the lab host
