Alright, lately one of my goals for this quarter is to get our lab working over IPv6 in addition to IPv4 for testing some of our software. Here’s a quick rundown on how to enable ipv6 on *most* cisco switches and Solaris, Linux and Windows.

Enable IPv6 on *most* Cisco switches (I used a 3750):
1. Telnet to the switch
2. Use “enable” to escalate privledges
3. configure terminal
4. sdm prefer dual-ipv4-and-ipv6 routing
5. end
6. reload (this will reboot the switch)

If you need to make sure it’s set correctly, telnet into the switch, enable and then run “show sdm prefer” and verify that it’s running ipv4-and-ipv6.

Enabling IPv6 on Solaris:
1. touch /etc/hostname6.<interfacename>
<interfacename> is the name of the hardware interface, something like ce0 or e1000g0, etc.

Enabling IPv6 on RedHat Linux
1. system-config-network, select the interface, edit the properties and check the box that says “Enable IPv6 on this interface”

Enabling IPv6 on Windows
1. ipv6 install at a command prompt.

You can test it using ping on Solaris and ping6 on Linux and Windows. Good luck!
