| | [Documentation]
| | ... | Set UP state on VPP interfaces in path on nodes in 2-node / 3-node
| | ... | circular topology. In case of 3-node topology create VLAN
| | ... | sub-interfaces between DUTs. In case of 2-node topology create VLAN
| | ... | sub-interface on dut1-if2 interface. Get the interface MAC addresses
| | ... | and setup ARPs. Setup IPv6 addresses with /64 prefix on DUT-TG links
| | ... | and set routing with prefix /64. In case of 3-node set IPv6 adresses
| | ... | with /64 prefix on VLAN and set routing on both DUT nodes with prefix
| | ... | /64. Set next hop of neighbour DUT interface IPv6 address. All
| | ... | interfaces are brought up.
