To route a subnet in ipv6 there are two possibilities:

I prefer neighbor proxy.

 

So I have to activate neighbor proxy in the router:

sysctl -w net.ipv6.conf.all.proxy_ndp=1

 

and I have to add entries for each client in the subnet like

ip -6 neigh add proxy 2001:0:0:1:211:d8ff:fe97:3273 dev eth0

 

This works well but is lost on reboot.

 

For the sysctl command there is /etc/sysctl.conf for permanent configuration.

 

If I create a file route-eth0 in the directory /etc/sysconfig/network-scripts/ with the above ip neighbor command, the interface eth0 is immediately down.

 

Restart of network brings:

Bringing up interface eth0:  Error: Unknown connection: 5fb06bd0-0bb0-7ffb-45f1-d6edd65f3e03.

                                                           [FAILED]

All Interfaces are NetworkManager controlled.

 

Ask for help:

-          where can I store the command for a permanent configuration?

-          Shall I not further use NetworkManager?

 

Thank you for help in advance

I would never use NetworkManager on a server.  It has never caused me anything but problems.
