[Bug 1358709] [NEW] SLAAC IPv6 addressing doesn't work with more than one subnet
Public bug reported:
When network has more than one IPv6 SLAAC (or dhcp-stateless) subnets,
the port receives SLAAC address only from first one, the second address
is from fixed IPs range.
Scenario:
1) create a network and two SLAAC subnets:
~$ neutron net-create net12
~$ neutron subnet-create net12 --ipv6-ra-mode=slaac --ipv6-address-mode=slaac --ip-version=6 2003::/64
| allocation_pools | {"start": "2003::2", "end": "2003::ffff:ffff:ffff:fffe"} |
| cidr | 2003::/64 |
| dns_nameservers | |
| enable_dhcp | True |
| gateway_ip | 2003::1 |
| host_routes | |
| id | 220b7e4e-b30a-4d5c-847d-58df72bf7e8d |
| ip_version | 6 |
| ipv6_address_mode | slaac |
| ipv6_ra_mode | slaac |
| name | |
| network_id | 4cfe1699-a10d-4706-bedb-5680cb5cf27f |
| tenant_id | 834b2e7732cb4ad4b3df81fe0b0ea906 |
~$ neutron subnet-create --name=additional net12 --ipv6-ra-mode=slaac --ipv6-address-mode=slaac --ip-version=6 2004::/64
| allocation_pools | {"start": "2004::2", "end": "2004::ffff:ffff:ffff:fffe"} |
| cidr | 2004::/64 |
| dns_nameservers | |
| enable_dhcp | True |
| gateway_ip | 2004::1 |
| host_routes | |
| id | e48e5d96-565f-45b1-8efc-4634d3ed8bf8 |
| ip_version | 6 |
| ipv6_address_mode | slaac |
| ipv6_ra_mode | slaac |
| name | additional |
| network_id | 4cfe1699-a10d-4706-bedb-5680cb5cf27f |
| tenant_id | 834b2e7732cb4ad4b3df81fe0b0ea906 |
Now let's create port in this network:
~$ neutron port-create net12
Created a new port:
+-----------------------+--------------------------------------------------------------------------------------------------+
| Field | Value |
+-----------------------+--------------------------------------------------------------------------------------------------+
| admin_state_up | True |
| allowed_address_pairs | |
| binding:vnic_type | normal |
| device_id | |
| device_owner | |
| fixed_ips | {"subnet_id": "220b7e4e-b30a-4d5c-847d-58df72bf7e8d", "ip_address": "2003::f816:3eff:fe55:6297"} |
| | {"subnet_id": "e48e5d96-565f-45b1-8efc-4634d3ed8bf8", "ip_address": "2004::2"} |
| id | 12c29fd4-1c68-4aea-88c6-b89d73ebac2c |
| mac_address | fa:16:3e:55:62:97 |
| name | |
| network_id | 4cfe1699-a10d-4706-bedb-5680cb5cf27f |
| security_groups | 65e77cc0-879c-4ed0-b647-d27d36844e0b |
| status | DOWN |
| tenant_id | 834b2e7732cb4ad4b3df81fe0b0ea906 |
As we see we get SLAAC IP from first subnet and fixed IP from second one.
Expected is to get SLAAC IPs from both subnets.
