Hello everyone,
I'm just confused about IPV6 configuration on KVM vps which not stable with me, I already followed the documentations on debian
http://docs.ovh.ca/en/guides-network-ipv6.html
Code:
auto eth0
iface eth0 inet static
address FailOver.IP
netmask 255.255.255.255
broadcast FailOver.IP
post-up route add DED.254 dev eth0
post-up route add default gw DED.254
pre-down route del DED.254 dev eth0
pre-down route del default gw DED.254
iface eth0 inet6 static
address 2607:5300:60:47b3::1
netmask 64
post-up /sbin/ip -f inet6 route add 2607:5300:60:47ff:ff:ff:ff:ff dev eth0
post-up /sbin/ip -f inet6 route add default gw 2607:5300:60:47ff:ff:ff:ff:ff
pre-down /sbin/ip -f inet6 route del 2607:5300:60:47ff:ff:ff:ff:ff dev eth0
pre-down /sbin/ip -f inet6 route del default gw 2607:5300:60:47ff:ff:ff:ff:ff
I also configured the /etc/sysctl.conf
Code:
net.ipv6.conf.eth0.autoconf=0
net.ipv6.conf.eth0.accept_ra=0
and restart the server to ensure that all the configuration effected however I can't ping from my PC and I can't ping from the server
this is my own configuration for ipv6
Code:
iface eth0 inet6 static
address 2001:41d0:2:3975::9
netmask 64
post-up /sbin/ip -f inet6 route add 2001:41d0:2:39ff:ff:ff:ff:ff dev eth0
post-up /sbin/ip -f inet6 route add default gw 2001:41d0:2:39ff:ff:ff:ff:ff
pre-down /sbin/ip -f inet6 route del 2001:41d0:2:39ff:ff:ff:ff:ff dev eth0
pre-down /sbin/ip -f inet6 route del default gw 2001:41d0:2:39ff:ff:ff:ff:ff
and this is the ping result
Code:
root@alsemany:~# ping6 -c 4 2001:4860:4860::8888
connect: Network is unreachable
I can ping the gateway
Code:
root@alsemany:~# ping6 -c 3 2001:41d0:2:39ff:ff:ff:ff:ff

rtt min/avg/max/mdev = 0.652/3.951/10.504/4.633 ms
is there any modules or configuration should be updated on the node ?
thanks
