Enabling/Disabling IPv6
In flight
- Note
- Enabling or disabling IPv6 this way is only in effect until next boot.
Disabling
sysctl -w net.ipv6.conf.all.disable_ipv6=1
sysctl -w net.ipv6.conf.default.disable_ipv6=1
sysctl -w net.ipv6.conf.lo.disable_ipv6=1Enabling
sysctl -w net.ipv6.conf.all.disable_ipv6=0
sysctl -w net.ipv6.conf.default.disable_ipv6=0
sysctl -w net.ipv6.conf.lo.disable_ipv6=0Manually adding an IPv6 Address
ifconfig eth0 add 2001:16d8:dd85:139::50/64Static configuration
Example of configuration of IPv6 on eth1 in /etc/network/interfaces
iface eth1 inet6 static

Add the following lines to /etc/sysctl.conf.
net.ipv6.conf.all.disable_ipv6 = 1
net.ipv6.conf.default.disable_ipv6 = 1
net.ipv6.conf.lo.disable_ipv6 = 1Configure as IPv6 Router
Uncomment the line net.ipv6.conf.all.forwarding=1 in /etc/sysctl.conf and reboot
Install Route Advertisement daemon for IPv6
