I must admit that the more I find out, the less impressed I am with 
some aspects  of IPv6 - and this is one of them. Historically I've 
been used to setting up the routers (note plural) to do the routing, 
and a DHCP server to configure clients.

Is RA an automatic function of IPv6 routers, or is it something the 
administrator configures ? If it's something the admin needs to 
configure, then I see little advantage (in a DHCP environment) over 
using DHCP to configure the client, if it's automatic then how does 
it know what the admin actually wants ?
