Hi Lar,
You can have a look at ENCAPS or HRA (http://www.huawei.com/file/download.do?f=3073), which are based on AS/LD-level routing.

However, I don't know if it already have been discussed so.... The proposal are simple: re-use AS-numbers into the forwarding of packets such that prefixes could be aggregated per AS. One simple implemetation is that the packets are tunneled and that the tunnel-address is associated to a AS-number. The AS-numbers can be assigned to the IP-addresses by DNS or by define a small address-prefix to AS-numbers. Comments? regards Lars Westberg, Ericsson Research
