6.6.2. 2n1l-10ge2p1x710-ethip4–ethip4udpgeneve-1tun-ip4base-scapy suite¶
L2BD with GENEVE L3 mode test cases
[Top] Network Topologies: TG-DUT1-TG 2-node circular topology with single links between nodes.
[Enc] Packet Encapsulations: Eth-IPv4 between TG-if1 and DUT1-if1 and Eth-IPv4-UDP-GENEVE-Eth-IPv4 between DUT1-if2 and TG-if2 for IPv4 routing over GENEVE tunnel.
[Cfg] DUT configuration: DUT1 is configured with IPv4 routing over GENEVE tunnel and 4 static IPv4 /24 route entries. DUT1 is tested with ${nic_name}.
[Ver] TG verification: Test Eth-IPv4 packet is sent by TG-if1 on link to DUT1-if1; on receive by TG-if2 the encapsulated packet is verified for correctness and its outer and inner IPv4 and MAC addresses, UDP ports and GENEVE vni and protocol number. Then test. Eth-IPv4-UDP-GENEVE-Eth-IPv4 packet is sent by TG-if2 on link to DUT1-if2; on receive by TG-if1 decapsulated packet is verified for correctness and its IPv4 and MAC addresses
[Ref] Applicable standard specifications: RFC791, RFC768, RFC8926.
