Once upon a time I had a lovely home network where IPv4 and IPv6 coexisted in perfect harmony. And then the big bad Juniper EX3200 switch was installed, and suddenly my IPv6 world ended. In a similar vein to the multicast issue I described in a previous post, out of the box, this (admittedly somewhat old) release of Junos OS kills IPv6 on the LAN.
I could argue – probably quite successfully – that a layer 2 switch should try and act like a layer 2 switch and not get its nose stuck into protocols that aren’t any of its business. But it is what it is, and what you really need to know is how to fix it, right?

I’m lucky enough to run a Juniper EX3200 as my home’s “core switch” (sounds good, right?). I love the Junos OS, and apart from the fans being tremendously noisy (in fact the hostname for this device is ‘noisy‘), it’s my pride and joy.
