-| ... | with one link between nodes. Test packets are sent in both directions
-| ... | and contain Ethernet header, IPv4 header and ICMP message. Ethernet
-| ... | header MAC addresses are matching MAC addresses of the TG node.
+| ... | *[Top] Network Topologies:* TG=DUT1 2-node topology with two links

+| ... | bridge-domain (L2BD) switching combined with static MACs; MAC
+| ... | learning enabled and Split Horizon Groups (SHG) depending on
+| ... | test case.
+| ... | *[Ver] TG verification:* Test ICMPv4 (or ICMPv6) Echo Request packets
