In this guide, we will focus on adding static IPv6 connectivity to a host that already has IPv4 connectivity.
Static network configuration for IPv4 on illumos is done in /etc/hostname.adaptername. Here's an example using a vmxnet3 adapter:
# cat /etc/hostname.vmxnet3s0 192.168.100.100 netmask 255.255.255.0 broadcast + up |
Things are very similar in the IPv6 world, although the syntax is a little different. To configure, create a file called /etc/hostname6.adaptername. Here's an example using a vmxnet3 adapter - and a private IPv6 address:
# cat /etc/hostname6.vmxnet3s0 addif fc00::100/64 up |
However, this is not enough. There's a service called Neighbor Discovery Protocol (NDP). It also needs a little work to correctly handle the IPv6 Route Advertisements on the local network. This is saved in the ndpd.conf file. It's not there by default, so create one with the following contents.
vi /etc/inet/ndpd.conf |
Add the following:
ifdefault TmpAddrsEnabled false ifdefault StatefulAddrConf true ifdefault StatelessAddrConf false |
It's good practice to do a reboot now; so you can check all services are coming up nicely, and the interface gets the correct addresses.
To test connectivity - we make use of the "ping"-command. It's a bit different than using it on e.g.: Linux, BSD,... In this case, we'll test against the local router at fc00::1
# ping -A inet6 fc00::1 fc00::1 is alive |
Notice the -A switch to set the address family to IPv6. That's it, all is working fine!
