... Its been a hell of a week!!
...obviously this is all in jest (NOT!!)

The Requirement

• The WG in Prague agreed to create a
  lower-layer-than-L7 solution to provide an
  endpoint with an appropriate LbyR URI for that
  endpoint.
• This doc creates a DHCP Option to deliver an LbyR
  URI to a client
• either dereference its location or
• hand out to other entities to learn this clients
  location (which is now the Target)

4
The Proposal

• To create a new (simple) DHCP Option for delivery
  of a LbyR URI

Whats Changed between -01 and -02

• Added a Valid-For field, indicating (in seconds)
  this URI should be considered valid
• A refresh will resolve this
• Make it clear a DHCP may or may not be co-located
  with a LIS
• Communication between these entities out-of-scope
• BTW target rules are not communicated over DHCP
• Made it clearer this doc does not address whats
  done outside DHCP
• Started section about harmful URI types
• Will expand this section on advice from Apps AD

6
Next Steps

• The WG hummed (in Prague) for an IETF,
  lower-than-L7 solution
• Does this doc meet that WG request?
• If so, I ask this become a WG doc to progress
• Obviously will incorporate consensus reaching
  suggestions into doc
