Open Stack

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 at localhost images]$ neutron net-show private6

+-------------------+--------------------------------------------------+

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
