Hi all,
I've been trying for a few days to understand how this should work. My guest OS
is Linux based, using ISC dhclient. In devstack I have configured an ipv6 net
and subnet:
[stack@localhost images]$ neutron net-show private6
+---------------------------+--------------------------------------+
| Field | Value |
+---------------------------+--------------------------------------+
| admin_state_up | True |
| availability_zone_hints | |
| availability_zones | nova |
| id | 55170162-305e-4d04-a159-2a141f0cd685 |
| mtu | 0 |
| name | private6 |
| port_security_enabled | True |
| provider:network_type | vxlan |
| provider:physical_network | |
| provider:segmentation_id | 1063 |
| router:external | False |
| shared | False |
| status | ACTIVE |
| subnets | 4ea435ac-0ede-4dbc-9096-d97c256cc4d5 |
| tenant_id | 9ede0af4cbe94caf8222b1dcfaac0754 |
+---------------------------+--------------------------------------+
[stack@localhost images]$ neutron subnet-show private-subnet6
+-------------------+--------------------------------------------------+
| Field | Value |
+-------------------+--------------------------------------------------+
| allocation_pools | {"start": "1:2:3:4::100", "end": "1:2:3:4::200"} |
| cidr | 1:2:3:4::/64 |
| dns_nameservers | 1:2:3:4::2 |
| enable_dhcp | True |
| gateway_ip | 1:2:3:4::1 |
| host_routes | |
| id | 4ea435ac-0ede-4dbc-9096-d97c256cc4d5 |
| ip_version | 6 |
| ipv6_address_mode | dhcpv6-stateful |
| ipv6_ra_mode | dhcpv6-stateful |
| name | private-subnet6 |
| network_id | 55170162-305e-4d04-a159-2a141f0cd685 |
| subnetpool_id | |
| tenant_id | 9ede0af4cbe94caf8222b1dcfaac0754 |
+-------------------+--------------------------------------------------+
When running dhclient on the interface, however, I am only able to acquire the
interface address, but not the interface default gateway. I suppose the default
gateway should be obtained through dhcp6 rather than neighbor discovery,
because I set both ipv6_address_mode and ipv6_ra_mode to dhcpv6-stateful.
Any ideas?
Thanks,
Andrei
