6.13.2. ethip6

6.13.2.1. 2n1l-10ge2p1x710-ethip6-ip6base-eth-2vhost-1vm-scapy suite

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-IPv6 for IPv6 routing on both links. [Cfg] DUT configuration: DUT1 is configured with IPv6 routing and two static IPv6 /64 route entries. Qemu Guest is connected to VPP via vhost-user interfaces. Guest is running VPP ip6 interconnecting vhost-user interfaces. [Ver] TG verification: Test IPv6 packets are sent in one direction by TG on links to DUT1; on receive TG verifies packets for correctness and their IPv6 src-addr, dst-addr and MAC addresses. [Ref] Applicable standard specifications: RFC2460, RFC4443, RFC4861

6.13.2.1.1. Local Template

Test uses two VRFs to route IPv6 traffic through two vhost-user interfaces. Both interfaces are configured with IP addresses from the same network. The VM is running VPP IPv6 forwarding to pass packet from one vhost-user interface to the other one. Arguments: - frame_size - Framesize in Bytes in integer. Type: integer - phy_cores - Number of physical cores. Type: integer - rxq - Number of RX queues, default value: ${None}. Type: integer
