Hi, I'm looking for input about how other people deal with this problem: We generate prefix filters for our customers from RADB using their AS or as-set. Our upstreams do the same for us. Our filters are generated with a simple WHOIS query and will pick up objects not only from RADB but from the various other IRRs that are mirrored in RADB. The problem is that it looks like at least one of our upstreams does not pick up the route objects that are in IRRs other than the one we asked them to use for us (RADB). One of our customers uses a different IRR and their routes did not get included in the filter generated by our upstream. Do we need to force all of our customers to use the same IRR as we do, or is there some way that we can support offering our customers a choice of IRRs just like our upstreams do for us? -Phil
