Trace route help

Thu Jul 17, 2014 6:49 pm

Hi guys,

having some issues at the moment with routing to an ipv6 site.
It looks like its an upstream routing loop in nlayer (GTT) but my service provider claims its never worked.
but I would appreciate some traceroutes and/or pings to archive.ubuntu.com (2001:67c:1360:8c01::18 & 2001:67c:1360:8c01::19)

Thanks
Footy

cool cool :)

@footy, in mlan's post (bgp4.as), in the telnet section is Oregon Route Views. Personally, my favorite. They peer w/ a bunch of ASNs. So a wide perspective. (route-views.oregon-ix.net / route-views.routeviews.org )
