IETF Stockholm/HiroshimaLISP Working GroupJuly 2009/Nov 2009
IETF LISP WG - July 2009LISP LIG Slide 2
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?
IETF LISP WG - July 2009LISP LIG Slide 3
draft-farinacci-lisp-lig-01.txt• LISP Internet Groper (lig)
– Fetches a database mapping entry– Both router and host lig available

Implementations• 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
