Description Nir Magnezi 2014-10-05 15:12:58 UTC

Description of problem:
=======================
I Created an IPv6 subnet with:
1. ipv6_ra_mode: dhcpv6-stateful
2. ipv6_address_mode: dhcpv6-stateful

Version-Release number of selected component (if applicable):
=============================================================
RDO Juno: openstack-neutron-2014.2-0.7.b3.el7.centos.noarch

How reproducible:
=================
100%

Steps to Reproduce:
===================
1. create a neutron network
2. create an IPv6 subnet:
# neutron subnet-create <IPv6_net_id> 2001:db2::/64 --name usecase2_ipv6_stateles_subnet --ipv6-address-mode dhcpv6-stateful --ipv6_ra_mode dhcpv6-stateful --ip-version 6
3. boot an instance with that network

Actual results:
===============
1. Instance got an IPv6 address
2. Instance is able to ping the neutron router IPv6 address.
3. default gw is not set

Expected results:
=================
The instance should have a default gw configured.

Additional Info:
================
I used tcpdump to search for RAs from within the instance, but I did not see any.

Comment 1 Nir Magnezi 2014-10-06 08:47:20 UTC

In addition, instances did not get IPv6 address.

Comment 2 Nir Magnezi 2014-10-06 08:50:34 UTC

Update to Results:
Actual results:
===============
1. Instance did not obtain IPv6 address
2. default gw is not set

Expected results:
=================
The instance should have IPv6 address a default gw configured.

Comment 3 Ihar Hrachyshka 2015-08-26 15:07:34 UTC

The upstream bug is fixed, and RDO is not a place to fix it anyway.
