Hi Nanog, For a research I want to distinguish the external AS peering from "show ip BGP". In other words I want to see which entry show a path that immediately sends packets to another AS. My understanding is that *status code* shows if the route is internal, right? Does this mean if the *'i' *is not present, the route is goes out of the AS in the next hop. On the same note, can I use "Next Hop" to identify such entries? I just included a sample report from a public looking glass in XO. show ip bgp 207.108.0.0/15 longer-prefixes BGP table version is 529230540, local router ID is 65.106.7.145 * * *Status codes: s suppressed, d damped, h history, * valid, > best, i - internal, r RIB-failure, S Stale, m multipath, b backup-path, x best-external, f RT-Filter, a additional-path Origin codes: i - IGP, e - EGP, ? - incomplete Network Next Hop Metric LocPrf Weight Path * 207.108.0.0/15 216.156.2.164 3 0 2828 209 i * 65.106.7.101 2 0 2828 209 i * 65.106.7.246 3 0 2828 209 i * 65.106.7.55 3 0 2828 209 i *> 216.156.2.162 2 0 2828 209 i * 65.106.7.54 3 0 2828 209 i * 65.106.7.252 2 0 2828 209 i * 216.156.2.160 2 0 2828 209 i * 65.106.7.56 3 0 2828 209 i * 216.156.2.165 2 0 2828 209 i * 65.106.7.144 2 0 2828 209 i Best Regards Reza Motamedi (R.M) Graduate Research Fellow Oregon Network Research Group Computer and Information Science University of Oregon
