Comment 1 Itzik Brown 2017-05-15 12:01:40 UTC
tempest IPv6 scenario tests relies on support for ping6.

Comment 2 Nir Yechiel 2017-07-20 09:02:28 UTC
@Itzik, @Sridhar, I guess this should be targeted to RHOSP 12 where we have IPv6 support?

Comment 3 Sridhar Gaddam 2017-07-20 09:32:07 UTC
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 [*].

Comment 6 Itzik Brown 2017-09-19 07:58:42 UTC
Used ping6 to ping the router's internal interface.
Version opendaylight-6.2.0-0.1.20170913snap58.el7.noarch

Comment 7 Waldemar Znoinski 2017-10-02 12:24:52 UTC
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)

Comment 9 Sridhar Gaddam 2017-10-10 12:20:51 UTC
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.


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
