What is says is A host receives prefixes in a Router Advertisement [RFC4861], which goes on to identify whether they are usable by SLAAC [RFC4862] [RFC4941] [RFC7217]. When no prefixes are usable for SLAAC, the Router Advertisement would normally signal the availability of DHCPv6 [RFC3315] and the host would use it to configure its addresses. In the latter case it will be generally the case that the configured addresses match one of the prefixes advertised in a Router Advertisement that are supposed to be on-link in that subnet. Since the host derives fundamental default routing information from the Route Advertisement, this implies that, in any network with hosts using multiple prefixes, each prefix SHOULD be advertised via on-link Prefix Information Options [RFC4861] by one of the attached routers, even if addresses are being assigned using DHCPv6. A router that advertises a prefix indicates that it is able to appropriately route packets with source addresses within that prefix. Tell me what to make it say.
