RE: OpenTransit (france telecom) depeers cogent
All, Here is an output of show ip bgp regexp _5511_ on my cogent facing router (ie with a full cogent feed)... Most of the prefixes with best paths that are not through cogent don't exist in my cogent route feed at all (even via a non FT path). It looks like things are still a bit wonky. http://as23265.net/cogent.txt Thanks, John van Oppen PocketiNet Communications AS23265 -----Ursprüngliche Nachricht----- Von: Patrick W.

As a cogent customer, I still see no routes to 217.167.0.0/16 (the route that holds www.francetelecom.com) via my cogent feed.
That /16 also appears to be unreachable from the looking glass on cogent's website still.
I can trace from Cogent to FT just fine.
Haven't checked all possible end points, but my spot check shows connectivity.
Replying to my own post, I still see some Cogent <-> FT strangeness. Tracing to www.opentransit.net works fine, but www.fracetelecom.com dies on the first hop. Spot checking other IPs in FT, they seem to work. Is it just the 'fracetelecom.com' sub-network that is still not connected? Anyone have any more info? -- TTFN, patrick

I am seeing wonkiness too. I have a default-free router peering exclusively with AS174 that's not seeing routes for hosts in rain.fr and francetelecom.com, and traces to those hosts die two hops into AS174. The same hosts are reachable via level3 and their traces go through on our routers that have multiple peerings. Note that the authoritative nameservers for francetelecom.com are in rain.fr and are not reachable via an exclusive cogent path. Hence, I am not able to even get DNS resolution on the cogent-only path. michael
