Introduction
- Network based Mobile IPv4 can be leveraged to
provide mobility service for IPv6 - The mobiles nodes with IPv6 stack can acquire
IPv6 address by number of ways e.g. IPv6CP and RA
and DHCPv6 - The solution described in this I-D defines these
scenarios
3
Solution Components
- Dual Stack HA that can assign the IPv6 HoA or
IPv6 prefix - The IPv6 prefix (HoA prefix) can be either shared
or can be unique per mobile node - Any v6 over v4 tunnel should suffice between
AR-HA and HA to IPv6 core - The MN need not be dual stack
