IPv6 routing to Renater lost in Geant

[(none)]

Connected to SSID ietf-1.x. When trying to reach my office (which is
fully v6), I get lost inside Geant:

It works from other networks (here, Hurricane Electric):

I think the problem is the network of crap.nic.fr reject ours more specific prefixes like the issue of nordunet.
