IPv4 routing test cases with vhost user interface

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

  • [Enc] Packet Encapsulations: Eth-IPv4-ICMPv4 for IPv4 routing on both links.

  • [Cfg] DUT configuration: DUT1 is configured with IPv4 routing and two static IPv4 /24 route entries. Qemu Guest is connected to VPP via vhost-user interfaces. Guest is running VPP ip4 interconnecting vhost-user interfaces.

  • [Ver] TG verification: Test ICMPv4 Echo Request packets are sent in one direction by TG on links to DUT1; on receive TG verifies packets for correctness and their IPv4 src-addr, dst-addr and MAC addresses.

  • [Ref] Applicable standard specifications: RFC791, RFC826, RFC792
