Summary0015981: Configuring host route via route6-<interface> may use incorrect address
DescriptionIf one creates a /etc/sysconfig/network-scripts/route6-<interface> file with the following information:

2402::ffff:ffff:ffff:ffff via 2001:1 dev <interface>

When restarting network (systemctl restart network.service), the created route is:

2402::ffff:ffff:ff:ffff via 2001::1 dev <interface> proto static metric 100 pref medium

Note that 00ff is used instead of ffff in the 7th set of digits. It seems that these bits are always zeroed.

It is odd in that if you add this directly using the route or ip command, there is no issue. It is something in what systemd does that causes this issue.

I'm not sure if this is the something in the scripts used, or how the network.service adds these routes.

Note: This issue also exists in 7.6.
