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.
However, it is intended to be used in an enterprise environment not a home environment, so not every default setting is ideal for the kind of things a typical home user might want.
Networking Field Day 5 (NFD5) drew to a close yesterday, and I have found myself sitting in a plane at around 32000 feet musing somewhat on the fact that my trip home has just been redirected via Chicago rather than Las Vegas (Viva Chicago!), but mostly reflecting on the week’s activities. If you aren’t sure what I’m talking about, read my recent post about the Networking Field Days.
What struck me more than anything was not just that the vendors presenting to NFD5 each delivered a very clear message, but that most of them delivered the same message.
Back in February 2012, Juniper announced that they were acquiring Mykonos, a Web Security vendor, and quite honestly my reaction was “uh, ok then”. I’d never heard of them, and figured I never would again – it would probably just have its technology sucked up into a firewall and integrated into a larger feature set. Evidently I was wrong, because on Friday afternoon at Networking Field Day 4, Juniper gave us a presentation and demonstration of their Mykonos product, and I have to say, I loved it.
First though, let’s figure out what this thing actually is.
This week I took the entry-level Juniper Networks Certified Internet Associate (JNCIA-JUNOS) exam, JN0-101, partly to fulfill a training objective for work, and partly because it has been on my “I really should get on and do that” list for about four years now. I passed pretty convincingly despite not really studying for it, but the real reason I’m mentioning it is that I had to book the exam through Prometric.
