+| L2 xconnect with VXLANoIPv4 initialized in a 3-node circular topology
+| | [Documentation]
+| | ... | Setup L2 xconnect topology with VXLANoIPv4 by cross connecting
+| | ... | physical and vxlan interfaces on each DUT. All interfaces are brought
+| | ... | up. IPv4 addresses with prefix /24 are configured on interfaces
+| | ... | between DUTs. VXLAN sub-interfaces has same IPv4 address as
+| | ... | interfaces.
