Essai mtr commande sur ip failover

gistfile1.txt
Les tests sur le serveur soyoustart on été faits en mode rescue
mac du serveur : link/ether 02:00:00:4c:f1:72
addresse IP failover du serveur inet 135.125.117.41/32
mac de mon laptop distant : link/ether c6:1b:b1:a0:42:b1
adresse LAN IP de mon laptop : inet 192.168.12.25/24
adresse IP publique de mon ldaptop : Pub 90.1.234.244
En mode rescue j'ai crée un bridge provisoire comme la documentation le demande a
https://docs.ovh.com/gb/en/dedicated/network-bridging/#troubleshooting_1
Pour le résumé, l'IP failover n'est pas contactable malgrès avoir suivie la documentation.
Les tests on été fait avec la commande ping (icmp) aucun ne passe vers l'IP failover et
l'IP failover ne peut utiliser la commande `mtr`
#
#
# sur le serveur en mode rescue

- voila la configuration avant de monter le bridge provisoire
