+| | ... | Set UP state on VPP interfaces in path on nodes in 3-node circular
+| | ... | topology. Get the interface MAC addresses and setup ARP on all VPP
+| | ... | interfaces. Setup IPv4 addresses with /24 prefix on DUT-TG and
+| | ... | DUT1-DUT2 links. Set routing for encrypted traffic on both DUT nodes
+| | ... | with prefix /8 and next hop of neighbour DUT or TG interface IPv4
+| | ... | address.
