The invention relates to a method for managing mobility of a mobile node, which is registered to a subset of network access entities (NAE). A location update is necessary because the MN moves from a first network area served by the first router to a second network area served by the second router, keeping the same IP addresses. In response to a trigger from the MN, the second router requests from the first router information on the registered NAEs, before they are informed to route data, destined for the mobile node, to the second router. Furthermore, the global IP addresses of the MN, created based on the prefixes of the registered NAEs, are updated. To expedite the address configuration after handover, the second router generates a IP address configuration message for the MN, comprising address prefixes of only the registered NAEs, without prior reception of a router solicitation message.
