Static IPv6 on Solaris 10

I tried to avoid it since I'm retiring these Solaris boxes soon, but I had to put static IPv6 on Solaris 10 so I could troubleshoot. So here's how to do it, and it's not quite the same as Solaris 9.

First, get your baseline.

sudo ifconfig -a6

sudo ifconfig -a

netstat -nr

Start with loopback, the easy one.

cd /etc

sudo touch hostname6.lo0

sudo ifconfig lo0 inet6 plumb up

Move on to an actual interface, changing eri0 to your interface as needed. This is a change from the Solaris 9 approach!

sudo vi hostname6.eri0

This time, the /etc/hostname6.eri0 file should contain 'addif ipv6:addr:ess/64 up' – not just the IPv6 address/prefix, but the extra directives as well.

Now make it so!

sudo ifconfig eri0 inet6 plumb up

sudo ifconfig eri0:1 inet6 plumb

sudo ifconfig eri0:1 inet6 ipv6:host:addy/64 up

Add a route to the default router, and put its address in that file to survive reboots.

sudo route add -inet6 default ipv6:rtr:addy

sudo vi /etc/defaultrouter6

You'll want ndp running too.

sudo /usr/lib/inet/in.ndpd -a

Check your work against your baseline.

sudo ifconfig -a6

sudo ifconfig -a

netstat -nr

OK! That seems to work for now.
