Chandra, This particular problem tends only to crop up every so often, but when it happens, the results can be devastating on a global scale, causing wide-scale outages across the entire Internet. The last couple of times, the problem has been caused by malformed attributes and has affect entire products lines, e.g. all Junipers routers in the propagation path, or all Cisco IOS boxes, or whatever. Or better still, when you have one vendor for your routers and another vendor for your RRs, you can be guaranteed of failure until all your upstreams figure out some way of filtering out the offending UPDATEs. It is a very real and very serious problem. There is lots of noise about this on nanog-l.
