Just to note, the route-views4 collector has a pretty diverse set of global multi-hop views. telnet://route-views4.routeviews.org/ http://www.routeviews.org/peers/peering-status.html http://www.routeviews.org/peers/route-views4.routeviews.org.txt John Kemp On 5/20/16 8:46 AM, Matthew Huff wrote: > Thanks, but I had checked a number of public looking glasses and only one had > the 46887 path (HE.net), wanted a more global check.

RE: Need BGP route check
Thanks, but I had checked a number of public looking glasses and only one had the 46887 path (HE.net), wanted a more global check. A number of responses are seeing only one or the other paths. The 14607 pre-pend is due to depref'ing 46887 earlier today when we had the instability.
