Description of problem: There is a need to support IPv6 in OpenStack when using OpenDaylight Version-Release number of selected component (if applicable): opendaylight-5.2.0-8.el7ost.noarch How reproducible: Steps to Reproduce: 1. 2. 3. Actual results: Expected results: Additional info:
tempest IPv6 scenario tests relies on support for ping6.
@Itzik, @Sridhar, I guess this should be targeted to RHOSP 12 where we have IPv6 support?
Yes @Nir, we can target this to RHOSP12. This feature is implemented via 7 patches spread across different components. All the necessary patches are merged in stable/carbon and Ocata. We are even running the IPv6 tempest scenario tests in Upstream CSIT. You can find the sample report here [*]. Patches: -------- Netvirt: Support ping6 for Neutron internal router interfaces - https://git.opendaylight.org/gerrit/#/c/58620/ networking-odl: Send port[fixed_ips] update to ODL Controller - https://review.openstack.org/#/c/477516/1 OpenflowPlugin: Bug 8535 Fix IPv6 OXMHeader Mask issue - https://git.opendaylight.org/gerrit/#/c/57694/ OpenflowPlugin: Nicira extension support for matching IPv6 Src/Dst (used with RegMove) - https://git.opendaylight.org/gerrit/#/c/56969/ GENIUS: Support API to configure IPv6 address as sourceAddress - https://git.opendaylight.org/gerrit/#/c/57026/ GENIUS: Support API for moving Src/Dest IPv6 addresses in NxRegMove action - https://git.opendaylight.org/gerrit/#/c/57027/ GENIUS: Utility api to configure icmpv6 type - https://git.opendaylight.org/gerrit/#/c/57072/ [*] https://jenkins.opendaylight.org/releng/job/netvirt-csit-1node-openstack-newton-nodl-v2-upstream-stateful-carbon/839/robot/netvirt-1node-openstack.txt/Tempest/Tempest/tempest.scenario.test_network_v6.TestGettingAddress.test_slaac_from_os/
Used ping6 to ping the router's internal interface. Version opendaylight-6.2.0-0.1.20170913snap58.el7.noarch
please check https://bugzilla.redhat.com/show_bug.cgi?id=1497652 for more low level info on the issue - it looks like it's affecting only one of two VMs spawned by the same tempest test (each on a different compute node)
*** Bug 1497652 has been marked as a duplicate of this bug. ***
Currently, tempest has 8 Scenario tests that validate ping6 support to router-interface along with other use-cases (like IPAM). We have support for ping6 for a dual-stack network as well as IPv6 only network. However, multiprefix networks (i.e., a network with multiple IPv6 subnets) has some gaps and is not officially supported in Netvirt. The following 4 tempest tests fall in the first category (i.e., dual-stack/single IPv6 network use-case) and they are supported. These 4 tests are validated in upstream OpenDaylight CSIT today. test_dualnet_slaac_from_os test_dualnet_dhcp6_stateless_from_os test_dhcp6_stateless_from_os test_slaac_from_os The next set of 4 tempest tests use multiple IPv6 subnets in a network and they are not supported. This is more of an RFE/Enhancement than a Bug. So, we have a separate bug to track its progress - https://bugzilla.redhat.com/show_bug.cgi?id=1498031 test_dualnet_multi_prefix_dhcpv6_stateless test_dualnet_multi_prefix_slaac test_multi_prefix_slaac test_multi_prefix_dhcpv6_stateless
