ip4 tunnels

eth2p-ethip4vxlan-l2bdbasemaclrn-dev

L2BD with VXLANoIPv4 test cases

  • [Top] Network topologies: TG-DUT1-TG 2-node circular topology with single links between nodes.

  • [Enc] Packet encapsulations: Eth-IPv4-VXLAN-Eth-IPv4-ICMPv4 on TG-DUT.

  • [Cfg] DUT configuration: DUT1 is configured with L2 bridge-domain switching combined with MAC learning enable. VXLAN tunnels are configured on links betwen TG and DUT.

  • [Ver] TG verification: Test Eth-IPv4-VXLAN-Eth-IPv4-ICMPv4 packet is sent by TG on link to DUT1; on receive TG verifies packets for correctness and their IPv4 src-addr, dst-addr and MAC addresses.

  • [Ref] Applicable standard specifications: RFC7348.
