all the AS numbers are the same

Are you running this trace from a BGP speaking router on your network? I'm also going to guess you're not taking full BGP routes from your upstreams? What exactly do you think is broken? As for the dropped traceroute probes, are you doing any sort of filtering of ICMP that could account for that? Note that dropped traceroute probes should _not_ be equated to packet loss without further investigation. jms
