31 | ... | - **[Top] Network Topologies:** TG=DUT1 2-node topology with two links \
32 | ... | between nodes.
34 | ... | - **[Enc] Packet Encapsulations:** Eth-IPv4 for L2 switching of \
37 | ... | - **[Cfg] DUT configuration:** DUT1 and DUT2 are configured with L2 \
38 | ... | bridge-domain (L2BD) MAC learning enabled; Split Horizon Groups (SHG) \
39 | ... | are set depending on test case; Namespaces (NM) \
40 | ... | are set on DUT1 with attached linux-TAP.
42 | ... | - **[Ver] TG verification:** Test IPv4 packets with IP protocol=61 \
43 | ... | are sent by TG on link to DUT1; On receipt TG verifies packets \
44 | ... | for correctness and their IPv4 src-addr, dst-addr, and MAC addresses.
46 | ... | - **[Ref] Applicable standard specifications:**

65 | | ... | - **[Ver]** Packet sent from TG is passed through all L2BD and \
66 | | ... | received back on TG. Then src_ip, dst_ip and MAC are checked.
