Title:
dhcpv6-stateful: error message in contradiction to spec
Status in neutron:
Invalid
Bug description:
The spec [1] points out how a subnet configured with ipv6 address mode
dhcpv6-stateful and ra mode none should behave:
"VM obtains IPv6 address and optional info from dnsmasq using DHCPv6
stateful" [1]
Now creating such an subnet and adding it as routers interface resulted in
the following error message:
neutron subnet-create --name subnet_ipv6-network --enable-dhcp --ip-version 6
--ipv6-address-mode dhcpv6-stateful ipv6-network 2003::/64
Created a new subnet:

Bad router request: IPv6 subnet 4c3f8b16-633c-492c-964e-20cbd4f0b30a
configured to receive RAs from an external router cannot be added to Neutron
Router.
--> This seems to be in contradiction to what described in the spec!
