俄勒冈大学(University of Oregon)有一个全球BGP路由表浏览的项目,通过他们的镜像路由器,可以查看到全球的BGP路由表。IPv4和IPv6的都可以查看到。查看方法:通过telnet登陆到下面这些路由器上,给的权限较低,但是都是可以查看路由表的。下面是可用的路由器列表:
route-views.routeviews.org
route-views2.routeviews.org
route-views3.routeviews.org
route-views4.routeviews.org
route-views6.routeviews.org
route-views.eqix.routeviews.org
route-views.isc.routeviews.org
route-views.kixp.routeviews.org
route-views.linx.routeviews.org
route-views.wide.routeviews.org
route-views.sydney.routeviews.org
route-views.saopaulo.routeviews.org
例如:通过route-views.routeviews.org来查看IPv4 BGP路由表信息如下:
route-views>show bgp all summary
