[afnog] AS36947 (Algeria telecom) strange behavior

[Fredy Kuenzler]

You could try to prefer routing towards OVH AS16276 using one of your alternative transits Telecom Italia AS6762 or Telefonica AS12956 (not a smart choice, IMHO, assuming that your network has mainly eyeballs, in other words is inbound heavy).

To achieve this rerouting you likely need to overwrite the shorter AS path of your Oranlink feed (ie _57023_16276_ is shorter than _12956_xxxxx_16276_ )

Hope this helps. If not I suggest to contact OVH NOC engineers, I suppose on parle Français à OVH.

Meilleurs salutations,
