Create an IPv4 neutron network (might not be mandatory but this is how I did it): # neutron net-create internal_ipv4_a --shared 2. Create an IPv4 subnet: # neutron subnet-create <IPv4_net_id> 192.168.1.0/24 --name internal_ipv4_a_subnet --ip-version 4 3. Create an IPv6 neutron network: # neutron net-create tenant_a_radvd_stateless --shared --provider:network_type=gre --provider:segmentation_id=123 4. Create an IPv6 subnet: # neutron subnet-create <IPv6_net_id> 2001:1234:1234::/64 --name internal_ipv6_subnet --ipv6-ra-mode dhcpv6-stateless --ipv6-address-mode dhcpv6-stateless --dns-nameserver 2001:4860:4860::8888 --ip-version 6 5. Create a neutron router: # neutron router-create router1 6. Attach subnets to the router # neutron router-interface-add <router_id> <ipv4_subnet> # neutron router-interface-add <router_id> <ipv6_subnet> 7. boot an instance with that network # nova boot tenant_a_instance_radvd_stateless --flavor m1.small --image <image_id> --key-name keypair --security-groups default --nic net-id=<ipv4_net_id> --nic net-id=<ipv6_net_id> Actual results: =============== 1. RAs reach the instance qbr but not to the instance tap device. 2. Instance did not obtain IPv6 address. Expected results: ================= IPv6 Router Advertisements should reach the instance. Additional info: ================ 1. Compute node and L3 agent deployed on different servers. 2. Communication between the nodes (RAs) done via GRE tunnels. 3. This worked before openstack-neutron-2014.2-11 4.
