My understanding is that transport over v6 is indeed on everyone's mind and absolutely is a goal for all the LISP people. So on this particular point, your concern is being addressed. What LISP has not done is actually improve the root problem of scaling up the number of multi-homed networks or locators. The cache scheme works if you imagine an ideal Internet where there is no DoS, but otherwise, it does not work. All the same problems of flow-cache routing still exist and LISP actually makes them worse in some cases, not better. It also adds huge complexity and risk but what value it adds (outside of VPN-over-Internet) is questionable at best. -- Jeff S Wheeler <j...@inconcepts.biz> Sr Network Operator / Innovative Network Concepts
