CENTOS and IPv6

TinyTunnel_Tom

Ok lets get started.

I got a SYS from OVH and IPv6 is playing up.

ping6 ipv6.google.com
PING ipv6.google.com(2a00:1450:400c:c04::8a) 56 data bytes
From 2001:41d0:8:528c::2 icmp_seq=1 Destination unreachable: Address unreachable
^C
--- ipv6.google.com ping statistics ---
4 packets transmitted, 0 received, +1 errors, 100% packet loss, time 3108ms

cat /etc/sysconfig/network
NETWORKING=yes
HOSTNAME=mspnat
NOZEROCONF=true
GATEWAY=37.59.xx.xx
NETWORKING_IPV6=yes
IPV6_DEFAULTDEV=eth0

 cat /etc/sysconfig/network-scripts/ifcfg-eth0
DEVICE=eth0
BOOTPROTO=static
IPADDR=37.59.xx.xx
NETMASK=255.255.255.0
ONBOOT=yes
GATEWAY=37.59.xx.xx
IPV6INIT=yes
IPV6ADDR=2001:41d0:8:xxx::2
IPV6_AUTOCONF=no
IPV6_DEFAULTGW=2001:41d0:8:xxxx::1

Anyone any ideas?

Can you ping the gateway?

Nope. It's the one OVH set too

AnthonySmith

That's your problem then

What configuration details have you been given by OVH?

Ovh gives default gateways that are outside the subnet they assign. You need a static route to the gateway or lower the prefix so they are in the same network.

@joereid extending the prefix beyond the allocation is not the greatest idea.

That's why I said to add a static route first

Clouvider

@joereid I'm not saying you haven't,

I'm just pointing out that the 2nd solution is no solution to this problem.
