Internet Engineering Task Force (IETF) R. Droms Request for Comments: 6276 P. Thubert Category: Standards Track Cisco ISSN: 2070-1721 F. Dupont Internet Systems Consortium W. Haddad Ericsson C. Bernardos UC3M July 2011 DHCPv6 Prefix Delegation for Network Mobility (NEMO) Abstract One aspect of network mobility support is the assignment of a prefix or prefixes to a mobile router for use on the links in the mobile network. This document specifies how DHCPv6 prefix delegation can be used for this configuration task. The mobile router plays the role of requesting router, while the home agent assumes the role of delegating router. When the mobile router is outside its home network, the mobile router also assumes the role of DHCPv6 relay agent, co-located with the requesting router function.

Introduction One aspect of network mobility support is the assignment of a prefix or prefixes to a mobile router for use on the links in Network Mobility (NEMO). DHCPv6 prefix delegation (DHCPv6PD) [RFC3633] can be used for this configuration task. The model of operation of DHCPv6PD for prefix delegation is as follows [RFC3633]. A delegating router is provided IPv6 prefixes to be delegated to requesting routers. A requesting router requests prefix(es) from the delegating router. The delegating router chooses prefix(es) for delegation, and responds with prefix(es) to the requesting router. The requesting router is then responsible for the delegated prefix(es). Note that DHCPv6 options for prefix delegation defined in [RFC3633] have been defined for general use across routers, and not only for mobile routers running the NEMO Basic Support protocol [RFC3963].Show full document text
