+| L2 bridge domains with Vhost-User for '${nr}' VMs initialized in a 3-node circular topology
+| | [Documentation]
+| | ... | Create pairs of Vhost-User interfaces for defined number of VMs on all
+| | ... | defined VPP nodes. Add each Vhost-User interface into L2 bridge
+| | ... | domains with learning enabled with physical inteface or Vhost-User
+| | ... | interface of another VM.
+| | ...
+| | ... | *Arguments:*
+| | ... | _None_
+| | ...
+| | ... | *Note:*
+| | ... | Socket paths for VM are defined in following format:
+| | ... | - /tmp/sock-${VM_ID}-1
+| | ... | - /tmp/sock-${VM_ID}-2
+| | ...
+| | ... | *Example:*
