Abstract

At the time of writing, network managers prefer Provider-Independent (PI) addressing for IPv6 to attempt to minimize the need for future possible renumbering. However, a widespread use of PI addresses will cause Border Gateway Protocol (BGP) scaling problems [RFC7010]. It is thus desirable to develop tools and practices that make IPv6 renumbering a simpler process to reduce demand for IPv6 PI space [RFC6879]. In this document, we aim to support HNP renumbering when the HNP in PMIPv6 [RFC5213] is not a PI prefix.

      Home Network Prefix Renumbering in Proxy Mobile IPv6 (PMIPv6)

Abstract

   In the basic Proxy Mobile IPv6 (PMIPv6) specification, a Mobile Node    (MN) is assigned with a Home Network Prefix (HNP) during its initial    attachment, and the MN configures its Home Address (HoA) with the    HNP.  During the movement of the MN, the HNP remains unchanged to    keep ongoing communications associated with the HoA.  However, the    current PMIPv6 specification does not specify related operations when    HNP renumbering has occurred (e.g., due to change of service provider    or site topology, etc.).  In this document, a solution to support HNP    renumbering is proposed, as an optional extension of the PMIPv6    specification.
