I realize that this is reaching way back, but you may want to have a look at the latest version of IRON: http://www.ietf.org/id/draft-templin-ironbis-12.txt IRON manages the internal routing systems for large virtual service provider networks. It deals with deaggregation and churn due to mobility internally, and does not expose the deaggregation and churn to the interdomain routing system. IRON is therefore an intradomain routing overlay network system, and can be used in conjunction with any interdomain routing system - including BGP and LISP.

There's no reason it can't beexactly that.It does provide advantages over the NAT-based solution (sessions cansurvivefailover).What do people think about Fred Templin's IRON multihomed tunneling approach (or LISP, I guess it can do it)? IRON should give you multihoming with stable IPv4 and IPv6 PA prefixes, even for incoming traffic. It's less reliable than BGP in theory since you'd be virtually single-homed to your IRON provider but that might be a worthwhile tradeoff since staying up is pretty much their purpose in life. You'd have to pay a third provider to terminate your tunnels, but that might be cheaper than paying an extra BGP tax to both of your physical providers. IRON appears to require much less configuration than BGP and it can also provide IPv6 over v4-only providers (good luck finding *two* broadband providers in the same location that provide IPv6 and BGP). -- Wes Felter IBM Research - Austin
