	IPv6 systems can send a Route Solicitation (RS) messages. These are answered by a Route Advertisement (RA) message that tells with prefixes exist and, when needed where the gateway for that prefix is. The client then can configure IPv6 addresses and routes.		IPv6 systems can send a Route Solicitation (RS) messages.
