CentOS - Jan 2015 - Where to configure proxy NDP in startup scripts?

Hi!

For my network setup I need the following commands:

sysctl -w net.ipv6.conf.all.proxy_ndp=1
ip -6 neigh add proxy 1234:5678:9abc:def0::2 dev eth2

The first command goes to /etc/sysctl.conf to enable it after a reboot.

But where do I put the "ip -6 neigh add proxy"?

	Best regards
