+| ...
+| ... | *[Top] Network topologies:* TG-DUT1-DUT2-TG 3-node circular topology
+| ... | with single links between nodes; TG=DUT1=DUT2=TG 3-node circular
+| ... | topology with double parallel links.
+| ... | *[Enc] Packet encapsulations:* Eth-IPv4-VXLAN-Eth-IPv4-ICMPv4 on
+| ... | DUT1-DUT2, Eth-IPv4-ICMPv4 on TG-DUTn for L2 switching of IPv4;
+| ... | Eth-IPv6-VXLAN-Eth-IPv6-ICMPv6 on DUT1-DUT2, Eth-IPv6-ICMPv6 on
+| ... | TG-DUTn for L2 switching of IPv6.
+| ... | *[Cfg] DUT configuration:* DUT1 and DUT2 are configured with L2
+| ... | bridge-domain (L2BD) switching combined with static MACs, MAC learning
+| ... | enabled and Split Horizon Groups (SHG) depending on test case; VXLAN
+| ... | tunnels are configured between L2BDs on DUT1 and DUT2.
+| ... | *[Ver] TG verification:* Test ICMPv4 (or ICMPv6) Echo Request packets
+| ... | are sent in both directions by TG on links to DUT1 and DUT2; on receive
+| ... | TG verifies packets for correctness and their IPv4 (IPv6) src-addr,
+| ... | dst-addr and MAC addresses.
+| ... | *[Ref] Applicable standard specifications:* RFC7348.
