I apologize for the wide distribution - I am a "new kid in town". I know that Annex G refers to inter-Domain connectivity... but my current interest is Inter-Zone/Intra-Domain. It is clear that GKs can broadcast LRQ msg to resolve non-local addresses (and cache them) , but this does not sound like a scaleable solution. I found a contribution APC-1434 from AT&T that gives some static and dynamic solution/guidelines. My questions are: 1) What is the status of the contribution ? anyone knows if this is accepted ? 2) Can someone point me to other places in any standard/contribution that address this issue (if such exist). If no special mechanism exist, and yet people agree that this is an issue (scaleability and redundancy) for Inter-Zone then let me know, and I can build a contribution that will offer those requirements. Yours, Haim. e-mail: Haim_Rochberger@3com.com
