Mobile IPv6
No need for foreign agent
- Use IPv6 auto-configuration to quickly obtain care-of-address
- Enough address space in IPv6 => no need for optimization done by typical FAs
Routing header is implemented more efficiently & securely
- Route optimization (triangle routing avoidance) can be done with less security concerns
- Source routing and tunneling can be used.
The mobile can send registration (binding) messages to peer (as well as home agent)
