I am configuring IPv6 address in a Debian machine, and this is what I have in my interface file.
auto eth0 iface eth0 inet6 static pre-up modprobe ipv6 address 2001:23:207:141:0:0:0:0 netmask 112 gateway 2001:23:207:129:0:0:0:0
When I run the command
/etc/init.d/networking restart, then I get following error.
SIOCSIFADDR file exist... failed to bring up eth0...
