For example I know there are enterprises that would like to multihome

can't justify the size of PI space that would guarantee them entry to
the global routing table.
Which is good. If they cannot justify PI space may be they should not
get into the global routing table.
The implication of this statement is that if you cannot afford the RIR fees,
the routers, the technical expertise to run those routers, the additional opex
associated with BGP-capable Internet connectivity, etc., the services/content
you provide don't deserve resiliency/redundancy/etc.
I have trouble seeing how this can be called good. A necessary evil given
broken technology perhaps, but not good.
LISP is about seperating the role of the ISP (as routing provider) from
the end user or content provider/consumer.
Yes, but as mentioned before the cost is in the edge, the benefit in
the core.
Being able to effectively multi-home without BGP, removing the need to ever
renumber, etc., all sound like benefits to the edge to me.
The economic equation is all wrong.
People keep saying this.
For core providers, the equation doesn't change. Well, OK, they may lose the
additional fees they get for BGP-capable connections and they won't have the
'benefit' of the cost of renumbering to reduce customer thrash, however they
continue to get paid for providing connectivity services. They might even save
some money in the long run as they won't need to replace their hamsters with
guinea pigs quite as frequently.
For edges, the addition of a network element gives them freedom and resiliency
at the cost of additional complexity and a bit of additional latency/reduced
bandwidth. However, it is the edges that would pay the cost to get the
benefit. I have trouble seeing how this economic equation is wrong.
There is not economic incentive for the edge to deploy LISP. We are facing
the same problem
that we have with IPv6.
Not really. For example, you (or somebody) have to edit/recompile code to use
IPv6. You do not have to recompile code to use LISP.
