Le routeur OVH a France-Ix (ou on peer avec eux) a toujours
eu l'ICMP un peu bizarre, par exemple il apparait en "???"
dans le sens ttnn => OVH :

$ mtr -rwc 5 91.121.221.253
Start: Wed Oct  7 19:16:04 2015
HOST: lgnuc              Loss%   Snt   Last   Avg  Best  Wrst StDev
  1.|-- h7.tetaneutral.net  0.0%     5    2.8   3.0   1.9   4.0   0.7
  2.|-- ???                100.0     5    0.0   0.0   0.0   0.0   0.0
  3.|-- rbx-g1-a9.fr.eu     0.0%     5   18.9  27.7  18.9  43.0  10.4
  4.|-- rbx-63-m1.fr.eu     0.0%     5   21.4  31.5  20.4  63.8  18.2

Ca passe bien par france-IX (VLAN 4032 aller et retour) au tcpdump sur
notre routeur :

19:16:08.371970 00:01:2e:2b:d2:07 > d4:6d:50:23:2b:eb, ethertype 802.1Q (0x8100), length 102: vlan 4032, p 0, ethertype IPv4, 91.224.149.165 > 91.121.221.253: ICMP echo request, id 26149, seq 10, length 64
19:16:08.387360 d4:6d:50:23:2b:eb > 00:01:2e:2b:d2:07, ethertype 802.1Q (0x8100), length 102: vlan 4032, p 0, ethertype IPv4, 91.121.221.253 > 91.224.149.165: ICMP echo reply, id 26149, seq 10, length 64

Sincèrement,
