Daniel, Thanks for post the writeup. Here is my initial comment. >route: [mandatory] [single] >origin: [mandatory] [single] >component: [optional] [multiple] >comm-list: [optional] [single] [guarded] >descr: [mandatory] [multiple] >remarks: [optional] [multiple] >notify: [optional] [multiple] >maintainer: [optional] [single] >changed: [mandatory] [multiple] >source: [mandatory] [single] I assume 'origin' has the same concept as 'creator' which we defined at our San Diego meeting. Just try to be sure. Does your definition above mean that one route can only have one 'origin'? If yes, then how do you plan to handle the proxy aggregate situation where it is possible that different ASs do the proxy aggregate for the same AS and therefore one route will have two origins? Also, how do you plan to handle the cases which ASs further aggregate the routes they hear from different ASs? i.e. aggregate beyond AS boundary. E.g. AS1 aggregate routes from AS2 and AS3 to a route called route-a, and AS4 does the same thing. Now route-a has two origins AS1 and AS4 (see the diagram below). AS1 / \ AS2 AS3 \ / AS4 Proxy aggregate like mentioned in your write up is not been done yet. But it will be very soon. We have customers line up for us to do proxy aggr for them. The software is almost ready so it will be done really SOON. Proxy aggregate for multi-homed AS will be done when people get desperte to reduce the routing table size, so does aggregation beyond AS boundary. So it is really desirable for routing registry to be designed to anticipate this will happen and be able to deal with it. If you allow one route has more than one orgin, that will do it. What is the concern of doing that? Thanks! --Jessica -------- Logged at Wed Apr 27 21:31:16 MET DST 1994 ---------
