Centos - IPv6 Support


Summary

After booting a Centos 7 based VPS you are unable to ping6 remote hosts, and received the error 'Beyond scope of source address'.

# ping6 google.com
PING google.com(ord38s01-in-x0e.1e100.net (2607:f8b0:4009:811::200e)) 56 data bytes
From fe80::f29f:c2ff:fec3:2284%eth0 (fe80::f29f:c2ff:fec3:2284%eth0) icmp_seq=1 Destination unreachable: Beyond scope of source address

Resolution

This issue is due to a missing newline in our network template that we are working to resolve.  As an interum resolution, please complete the following steps:

echo "" >> /etc/sysconfig/network-scripts/ifcfg-eth0
ifdown eth0 && ifup eth0

This will append a newline to the end of the ifcfg file, and reload networking.  Once you complete this step, you should be able to ping Google.  Please reboot your VPS to ensure the VPS boots in a state with IPv6 working correctly.
