Basic MIPv6 protocol provides the mobility support for mobile nodes. However, this protocol does not concern access technologies and suggest using complex IPSec to protect MIPv6 signaling between Mobile Nodes and Home Agents. According to different scenarios deployed for MIPv6 network, access service providers could be independent of MIPv6 service providers, which is split scenario.
