overlay test cases status

Tempest/Functest

• The basic Overlay IPv6 Testing (i.e. tenant IPv6 networks using Neutron) are loaded by Tempest by default in the Smoke Scenario (Tempest Scenario Testing).

  https://github.com/openstack/tempest/blob/master/tempest/scenario/test_network_v6.py

  the process is 

  1. Create network with subnets:
     1.1. one IPv4 and
     1.2. one or more IPv6 in a given address mode
  2. Boot 2 VMs on this network
  3. Allocate and assign 2 FIP4
  4. Check that vNICs of all VMs gets all addresses actually assigned
  5. Each VM will ping the other's v4 private address
  6. If ping6 available in VM, each VM will ping all of the other's v6 addresses as well as the router's

• This can be reused as the basis.

Yardstick

• already have Overlay IPv6 Testing for specific use case “Service VM as IPv6 vRouter”. https://git.opnfv.org/cgit/yardstick/tree/tests/opnfv/test_cases/opnfv_yardstick_tc027.yaml

• Some hardcoded names, IP addresses etc. need change, of course.  test case description will also be added in the test case.

  (Note: there should be a JIRA task here for yardstick, https://github.com/openstack/tempest/blob/master/tempest/config.py#L632 can be good examples, such as packetsize, ping_count, etc. During the release time, some problems with the developing)

underlay test cases status, Not completed ready, will develop in later releases

3, installers & SDN controller support status

3.1 since all installers are inherited from upstream openstack, for ipv6 with openstack only, see detail in the Gap analysis in ipv6-enabled OPNFV project https://git.opnfv.org/cgit/ipv6/tree/docs/userguide/featureusage.rst

3.2 ODL support Gap analysis is also shown in https://git.opnfv.org/cgit/ipv6/tree/docs/userguide/featureusage.rst, lack of ONOS/opencontrail, etc, waiting for contribution.
