Background solution

• Presented first time at IETF-69.. just a recap!
• NetLMM WG is finalizing the PMIPv6 protocol, its
  IPv4 enhancements and MIP6-PMIP6 transition
• Deployments need/benefit/require AAA backend
  support for PMIPv6 bootstrapping, management and
  accounting
• This I-D aims to provide Diameter support for
• MAG (NAS) to AAA interface
• LMA (HA) to AAA interface
• Bootstrapping of MAG to LMA SA (when needed)
• Generic PMIPv6 bootstrapping

Issues needing a closer check

• RADIUS interworking
• There is RADIUS draft around draft-xia-netlmm-rad
  ius-01
• Accounting on MAG LMA
• Session management
• MN-HoA DNS update on behalf of the MN?
• Intrface identifier MN identifier assignment
  details
• MIP6-PMIP6 interactions
• PMIPv6 bootstrapping details from different SDOs
  point of view
