It's a feature. Everything working as intended. DHCPv6 protocol is 
designed to provide addresses and options. It is not supposed to configure 
routing. To do that, one should use router advertisements. In Linux

Since many people consider this as an issue, I'll think about modifying 
this behaviour. For example client will add addresses with /64 prefix. But 
this feature will require checking some kind of option like
