Joel, You're misunderstanding my description. I admit my slides are short of wordings.
- Node addresses are local to each AS, so each AS manages only their own member list. ASs don't keep full list of all hosts in all customers. - As soon as a packets exits an AS to the inter-domain region, the node address loses its meaning(or is not relevant), and the IDR routers would only look at the dst AS# imbedded in the packet to execute IDR.
