Abstract

This document describes an optional extension to RouterAdvertisement messages for communicating default router preferencesand more-specific routes from routers to hosts. This improves theability of hosts to pick an appropriate router, especially when thehost is multi-homed and the routers are on different links. Thepreference values and specific routes advertised to hosts requireadministrative configuration; they are not automatically derivedfrom routing tables. [STANDARDS-TRACK]
