Title: IPv6 "Automatic, only DHCP" configuration results in no default route Status in “network-manager” package in Ubuntu: New Bug description: The local network uses SLAAC configuration (with the OtherConfig-Bit in the RA set) as default configuration for devices. Some devices however should use a different IPv6 address assigned by statefull dhcp. Obviously, the ManagedConfiguration bit in the RA is not set, as this would break the SLAAC clients. When choosing "Automatic, only DHCP" for IPv6 configuration in the network manager (which translates into method=dhcp or NM_SETTING_IP6_CONFIG_METHOD_DHCP), the IPv6 address and the IPv6 DNS Servers are successfully assigned, but there is no ipv6 default route. This is because NM_SETTING_IP6_CONFIG_METHOD_DHCP reconfigures sysctl to drop all RAs (accept_ra=0), but DHCPv6 still has no option to set the gateway IPv6 address (neither its link-local or globally valid address). So I currently cannot have only some clients use statefull DHCPv6, which is what I want. Solution: either a) add an option to set sysctl accept_ra=1, autoconf=0 ; so the client will not use a SLAAC address but still add a default route based on RA or b) add a gateway option to DHCPv6. This bug is to change network manager so the solution a) gets implemented, as this can be implemented in NetworkManager. Solution b) would need to be implemented in isc-dhcp-client and might need an updated RFC, but would allow for different use cases (i.e. http://www.ietf.org/mail-archive/web/ipv6/current/msg08684.html).
