Sure.
Here is my text (two paragraphs instead of one :-)) Please feel free to add
more, I believe other people, e.g. Brian Carpenter can also help.

The issue is delivering routes to the hosts. RFC 4191 defines Router
Advertisement extensions for communicating default router preferences and
more-
   specific routes from routers to hosts. The draft on IPv6 RA Options for
Next Hop Routes, draft-sarikaya-6man-rfc4191bis-00 proposes some new  Router
   Advertisement options for configuring next hop routes on the mobile
   or fixed nodes.

DHCP can also be used for delivering routes, as in
draft-ietf-mif-dhcpv6-route-option-05. DHCPv6 Route Options can be defined
basically to mimic the RA options defined in RFC 4191 as well as with some
extensions such as the next hop address. DHCP approach claims the advantage
of being applicable to configuring the routers, e.g. residential
   gateways (RG) or Customer Premises Equipment (CPE) as well as the hosts.
