  22 |test purpose  | To do a basic verification that IPv6 connectivity is within  |
  23 |              | acceptable boundaries when ipv6 packets travel between hosts |
  24 |              | located on same or different compute blades.                 |
  25 |              | The purpose is also to be able to spot trends. Test results, |
  26 |              | graphs and similar shall be stored for comparison reasons and|
  27 |              | product evolution understanding between different OPNFV      |
  28 |              | versions and/or configurations.                              |

  31 |configuration | file: opnfv_yardstick_tc027.yaml                             |
  32 |              |                                                              |
  33 |              | Packet size 56 bytes.                                        |
  34 |              | SLA RTT is set to maximum 30 ms.                             |
  35 |              | ipv6 test case can be configured as three independent modules|
  36 |              | (setup, run, teardown). if you only want to setup ipv6       |
  37 |              | testing environment, do some tests as you want, "run_step"   |
  38 |              | of task yaml file should be configured as "setup". if you    |
  39 |              | want to setup and run ping6 testing automatically, "run_step"|
  40 |              | should be configured as "setup, run". and if you have had a  |
  41 |              | environment which has been setup, you only wan to verify the |
  42 |              | connectivity of ipv6 network, "run_step" should be "run". Of |
  43 |              | course, default is that three modules run sequentially.      |

  47 |              |                                                              |
  48 |              | Ping6 is normally part of Linux distribution, hence it       |
  49 |              | doesn't need to be installed.                                |

  57 |applicability | Test case can be configured with different run step          |
  58 |              | you can run setup, run benchmark, teardown independently     |
  59 |              | SLA is optional. The SLA in this test case serves as an      |
  60 |              | example. Considerably lower RTT is expected.                 |
  61 |              |                                                              |
  62 +--------------+--------------------------------------------------------------+
  63 |pre-test      | The test case image needs to be installed into Glance        |
  64 |conditions    | with ping6 included in it.                                   |
  65 |              |                                                              |
  66 |              | For Brahmaputra, a compass_os_nosdn_ha deploy scenario is    |
  67 |              | need. more installer and more sdn deploy scenario will be    |
  68 |              | supported soon                                               |

  73 +--------------+--------------------------------------------------------------+
  74 |step 1        | To setup IPV6 testing environment:                           |
  75 |              | 1. disable security group                                    |
  76 |              | 2. create (ipv6, ipv4) router, network and subnet            |
  77 |              | 3. create VRouter, VM1, VM2                                  |
  78 |              |                                                              |
  79 +--------------+--------------------------------------------------------------+
  80 |step 2        | To run ping6 to verify IPV6 connectivity :                   |
  81 |              | 1. ssh to VM1                                                |
  82 |              | 2. Ping6 to ipv6 router from VM1                             |
  83 |              | 3. Get the result(RTT) and logs are stored                   |
  84 |              |                                                              |
  85 +--------------+--------------------------------------------------------------+
  86 |step 3        | To teardown IPV6 testing environment                         |
  87 |              | 1. delete VRouter, VM1, VM2                                  |
  88 |              | 2. delete (ipv6, ipv4) router, network and subnet            |
  89 |              | 3. enable security group                                     |
  90 |              |                                                              |
  91 +--------------+--------------------------------------------------------------+
  92 |test verdict  | Test should not PASS if any RTT is above the optional SLA    |
  93 |              | value, or if there is a test case execution problem.         |
