[CentOS] CentOS 6 IPv6: neighbor and restart network

Hallo,

for using the ipv6 neighbor functions, I have to execute commands like ip -6 neigh add proxy 2001::211:d8ff:fe97:3273 dev eth0 to publish the ip of computers in the subnet.

To execute them on reboot, I have included these commands in /etc/rc.d/rc.local

Also after each restart of the network, I have to execute these commands too.

So: how can I always execute

/etc/rc.d/rc.local

after

service network restart

My idea: Is it possible to rename /etc/network to /etc/network_original and to create a new shell script /etc/network to execute both?

Other/better advice?

Thank you for help in advance.
