Your RA stated that there is no DHCPv6 server on the network for normal 
addresses. So this network is stateless.
If you have configured a DHCPv6 server, then you need to instruct your 
RA server to toggle the M bit for managed addresses or the O bit to get 
Other information (such as DNS) from the DHCPv6 server.

If you're after something else, or want to force DHCPv6 in the case of a 
faulty RA server then request it explicitly in dhcpcd.conf using the 
ia_na or ia_pd options under an interface block.
