Openstack version: Ocata Mech driver: OVS Security: Linuxbridge Hello!
Anyone have any idea why DHCP for IPv4 works fine but DHCP for IPv6 doesn't? With Stateless or just SLAAC, the VM's calculate a correct IPv6 address from the IPv6 prefix I've assigned, but (for stateless) the instances doesn't get any of the options, like DNS, etc... Stateful doesn't work at all. I configure a stateful network using a command like this: openstack subnet create --allocation-pool start=2604:ffff:ffff:ffff::2,end=2604:ffff:ffff:ffff:ffff:ffff:ffff:ffff --ip-version 6 --ipv6-address-mode dhcpv6-stateful --ipv6-ra-mode dhcpv6-stateful --dns-nameserver 2620:0:ccc::2 --network cust01-v6_net0 --subnet-range 2604:ffff:ffff:ffff::/64 cust01-v6_sub0 But none of the instances added to that network acquire a v6 address ever. I can statically assign the selected IPv6 address to the respective instance and it can then ping out using v6 just fine. I can also add IPv6 DNS addresses to resolv.conf and the instance can correctly resolve as well. This issue happens on both Linux and Windows instances... Any ideas? Thanks in advance! Steve
