Public bug reported:
Description of problem:
=======================
I Created n radvd IPv6 subnet with:
- ipv6_ra_mode: dhcpv6-stateful
- ipv6_address_mode: dhcpv6-stateful
Meaning:
a. The Neutron DHCP agent (dnsmasq) provides IP addresses and additional
parameters.
b. Neutron router (radvd) sends out RAs.
Version-Release number of selected component (if applicable):
=============================================================
openstack-neutron-2014.2.1-2
How reproducible:
=================
2/2
Steps to Reproduce:
===================
1. Create an IPv6 neutron network:
# neutron net-create tenant_a_radvd_stateful --shared
--provider:physical_network=ipv6_vlan_range --provider:network_type=vlan
--provider:segmentation_id=64
2. Create an IPv6 subnet:
# neutron subnet-create <IPv6_net_id> 2001:65:65:65::1/64 --name
tenant_a_radvd_stateless_subnet --ipv6-ra-mode dhcpv6-stateless
--ipv6-address-mode dhcpv6-stateless --dns-nameserver 2001:4860:4860::8888
--ip-version 6
3. Create a neutron router:
# neutron router-create router1
4. Attach subnet to the router
# neutron router-interface-add <router_id> <ipv6_subnet>
5. boot an instance with that network
# nova boot tenant_a_instance_radvd_stateful --flavor m1.small --image
<image_id> --key-name keypair --security-groups default --nic
net-id=<ipv6_net_id>
Actual results:
===============
# nova show <instance_id> | grep network
| tenant_a_radvd_stateful network | 2001:64:64:64::5
|
# neutron port-show <port_id> | grep fixed_ips
| fixed_ips | {"subnet_id": "<subnet_id>", "ip_address":
"2001:64:64:64::5"} |
Dispite that fact that the port mac address matches the instance NIC,
the IP obtained by the instance is different.
Expected results:
=================
In this case, the NIC IP address is: 2001:64:64:64:f816:3eff:fe2b:6197
Additional info:
================
1. Instance guest image: rhel7
2. Hypervisor: rhel7
