+| Initialize L2 bridge domains with Vhost-User and VLAN with DPDK link bonding in a 3-node circular topology
+| | [Documentation]
+| | ... | Create two Vhost-User interfaces on all defined VPP nodes. Setup VLAN
+| | ... | on EthernetBond interfaces between DUTs. Add one Vhost-User interface
+| | ... | into L2 bridge domains with learning enabled with physical interface
+| | ... | towards TG and other Vhost-User interface into L2 bridge domains with
+| | ... | learning enabled with VLAN sub-interface. All interfaces are brought
+| | ... | up.
+| | ...
+| | ... | *Arguments:*
+| | ... | - bd_id1 - Bridge domain ID. Type: integer
+| | ... | - bd_id2 - Bridge domain ID. Type: integer
+| | ... | - sock1 - Sock path for first Vhost-User interface. Type: string
+| | ... | - sock2 - Sock path for second Vhost-User interface. Type: string
+| | ... | - subid - ID of the sub-interface to be created. Type: string
+| | ... | - tag_rewrite - Method of tag rewrite. Type: string
