User RequirementsUser 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?

ImplementationsImplementations

• Dino -> NX-OS on Titanium– Runs on ITR/ETR/PTR/MR/MS/ALT-router

• IOS Crew -> IOS Implemenation• Dave -> Linux/FreeBSD/Mac OS

– Runs anywhere (I hope :-)) – Doesn’t have to be a LISP site– http://github.com/davidmeyer/lig

• Implementations reflect both– draft-ietf-lisp-05.txt– draft-ietf-lisp-ms-04.txt
