Technical Summary
 This document describes an optional extension to Router
 Advertisement messages for communicating default router preferences
 and more-specific routes from routers to hosts. This improves the
 ability of hosts to pick an appropriate router, especially when the
 host is multi-homed and the routers are on different links. The
 preference values and specific routes advertised to hosts require
 administrative configuration; they are not automatically derived
 from routing tables.

RFC Editor Note
Dear RFC Editor,
Please make the following change in section 1 (Introduction):
OLD:
This document describes an optional extension to Neighbor Discovery
Router Advertisement messages for communicating default router
preferences and more-specific routes from routers to hosts. This
improves the ability of hosts to pick an appropriate router for an
off-link destination.
NEW:
This document describes an optional extension to Neighbor Discovery
Router Advertisement messages for communicating default router
preferences and more-specific routes from routers to hosts. This
improves the ability of hosts to pick an appropriate router for an
off-link destination.
Note that since these procedures are applicable to hosts only, the
forwarding algorithm used by the routers (including hosts with enabled IP
forwarding) is not affected.
