+| ... | Eth-IPv6-NS/NA on links TG-DUT. IPv6 routing tests use circular 3-node
+| ... | topology TG - DUT1 - DUT2 - TG with one link between the nodes. DUT1 and
+| ... | DUT2 are configured with IPv6 routing and static routes. Test ICMPv6
+| ... | Echo Request packets are sent in both directions by TG on links to DUT1
+| ... | and DUT2 and received on TG links on the other side of circular
+| ... | topology. On receive TG verifies packets IPv6 src-addr, dst-addr and MAC
+| ... | addresses.
