8.2.8. L2BD Ethernet Switching¶

8.2.8.1. eth2p-eth-l2bdbasemaclrn-eth-2vhost-1vm-func¶

L2 bridge-domain test cases

[Top] Network Topologies: TG=DUT=VM 3-node topology with VM and double parallel links.

[Enc] Packet Encapsulations: Eth-IPv4-ICMPv4 for L2 switching of IPv4; Eth-IPv6-ICMPv6 for L2 switching of IPv6 use. Both apply to all links.

[Cfg] DUT configuration: DUT1 is configured with two L2 bridge-domains (L2BD) switching combined with MAC learning enabled.

[Ver] TG verification: Test ICMPv4 (or ICMPv6) Echo Request packets are sent in both directions by TG on links to DUT1 via VM; on receive TG verifies packets for correctness and their IPv4 (IPv6) src-addr, dst-addr and MAC addresses.
