Gente, eu e um amigo estamos ficando de cabelos em pé ... pois mesmo configurando a placa de rede da forma que está a baixo ele não pinga, o que está acontecendo ? 

[root@xxxxxx ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0:0
DEVICE=eth0:0
BOOTPROTO=static
IPADDR=198.xxxx
NETMASK=255.255.255.255
BROADCAST=198.xxxx
ONBOOT=yes

[root@ns4008649 ~]# cat /etc/sysconfig/network-scripts/ifcfg-eth0:2
EVICE=eth0:2
BOOTPROTO=static
IPADDR=198xxx..xxxx
NETMASK=255.255.255.255
BROADCAST=198.1xxx6
ONBOOT=yes


[root@xxxx ~]#  ifup eth0:0
[root@xxx ~]#  ifup eth0:1
[root@xxx ~]#  ifup eth0:2

PROBLEMA : NÃO CONSIGO PINGAR eth0:0 E NEM A eth0:1 , POREM CONSIGO eth0


RESPOSTA DA OVH

I have checked that your IP failovers XXX.1XX.XX2.174,
XXX.000.XXX.175 e XXX.XXX.XXX.176 are not responding to
ping.
I have also checked the switch and ACL from my side, and
did not notice any issue.

Packet loss on the routers is not an issue, what counts
is the packets reaching to the relevant IP.

Tente;

 

DEVICE="eth0:1"
ONBOOT="yes"
BOOTPROTO="static"
IPADDR="IP.AD.RE.SS"
NETMASK="255.255.255.255"
BROADCAST="IP.AD.RE.SS"
GATEWAY="IP.DO.GATEWAY"
 
Já na questão do gateway, o gateway da OVH é sempre o final 254 em sua range de IP, que no caso se o seu IP fosse
 
8.8.8.8, o gateway seria 8.8.8.254
 
Tente efetuar o procedimento acima.
