User Requirements

• Need to answer the following questions
• Is the mapping system working?
• Is the MR and MS service interface working?
• Is the site registered to the MS?
• Does all of the above work for IPv4 and IPv6?
• What is the EID-prefix of a site?
• What is the locator-set and parameters for a
  map-cache entry?
• Does locator-set and parameters vary depending on
  where the Map-Request is originated from?

Implementations

• Dino -gt NX-OS on Titanium
• Runs on ITR/ETR/PTR/MR/MS/ALT-router
• IOS Crew -gt IOS Implemenation
• Dave -gt Linux/FreeBSD/Mac OS
• Runs anywhere (I hope -))
• Doesnt have to be a LISP site
• http//github.com/davidmeyer/lig
• Implementations reflect both
