  2. SITE-LOCAL STATUS • Address Architecture defines format: • Address Selection defines selection rules • Work Ongoing on • Node Requirements • Scoped Address Architecture | 10 | | bits | 54 bits | 64 bits | +----------+-------------------------+----------------------------+ |1111111011| subnet ID | interface ID | +----------+-------------------------+----------------------------+

  3. ISSUES IN SEVERAL AREAS • Site Border Router • Multi-Site Routers • Site-Local in Routing Protocols? • Multi-Site Hosts • DNS • Applications

  4. CHOICES FOR IPv6 W.G. • Remove Site-Local • Limited Usage • Only used in disconnected sites • No Multi-Site Nodes, DNS, etc. • Moderate Usage • Simple Site-Border Router • No Multi-Site Host or Router Requirement • Two-Faces/Split DNS • Full Usage • Require all nodes to be multi-site • Routing Protocols aware of site boundaries • Multi-Site DNS

  5. WHAT SHOULD THE W.G. DO? • Lets try hard to get a consensus around how to proceed. • This is a controversial issue • Not everyone will be happy • Find a way to move forward

  6. OTHER TALKS

  7. WHAT NEXT ?
