7.8. ip6_tunnels

7.8.1. 10ge2p1x710-ethip6lispip4-ip6base-ndrpdr suite

RFC6830: Pkt throughput Lisp test cases

  • [Top] Network Topologies: TG-DUT1-DUT2-TG 3-node circular topology with single links between nodes.

  • [Enc] Packet Encapsulations: Eth-IPv6-LISP-IPv4 on DUT1-DUT2, Eth-IPv6 on TG-DUTn for IPv6 routing over LISPoIPv4 tunnel.

  • [Cfg] DUT configuration: DUT1 and DUT2 are configured with IPv6 routing and static routes. LISPoIPv4 tunnel is configured between DUT1 and DUT2. DUT1 and DUT2 tested with ${nic_name}.

  • [Ver] TG verification: TG finds and reports throughput NDR (Non Drop Rate) with zero packet loss tolerance and throughput PDR (Partial Drop Rate) with non-zero packet loss tolerance (LT) expressed in percentage of packets transmitted. NDR and PDR are discovered for different Ethernet L2 frame sizes using MLRsearch library.

  • [Ref] Applicable standard specifications: RFC6830.
