Re: [HELP] Cisco 1811 is crashing

Juniper is very popular among big ISPs. I remember taking a walk through a very large DC in San Jose California, and I reckon I saw more Juniper kit in there than Cisco.

Even if you dont "switch" from Cisco to Juniper, being multi skilled in multiple vendors can only be good for you when it comes to job hunting. That might be the edge you have over the other guys...

I picked up my first Juniper router back in 2008 or so, just a lowly J2300, and compared to traditional IOS, JunOS blows Cisco way out of the water, especially from a configuration point of view.

If you want something new and cheap, the SRX line is quite competitively priced. I picked up a SRX100B for a little over AUD$500, brand new. It runs all of the latest JunOS versions, whereas my J2300 is limited to 9.3. Newer J series (like the J2320, basically anything thats not a Jx300) also run the latest images but are a bit more expensive.

Still, its good for getting a foot in the door, and I still use my J2300 in my lab. Looking at picking up an M7i or two soon, logical systems are a really intriguing feature, allowing you to run up to 15 individual routers on a single box, very much like a VM. Good for building complex topologies without the mess!

I wonder how loud the fan noise is. Is it like the old Cisco Catalyst 3550-24 port switch? Or maybe it is more like Cisco 3725 router?

M7i? Compared to SRX100B you bought, the M7i probably costs 4 times more; still a lot of money for some of us not to mention the fan noise

If you want to play around with the virtualization, you can just buy another SRX100 since JUNOS uses the same technology between the routers, SRX firewalls, and EX switches.

The fan noise from the J2300 is a bit of a problem. Its got a very high pitched whiney fan in it, and it seems to like speeding up and slowing down a lot so it gets a little annoying after a while. I tried running it with the cover off, but no difference. :-/

But since its a generic x86 (Celeron in fact) based box with a run of the mill 3-wire fan, I could potentially find a slower speed quieter fan to clip on top of the heat sink. Maybe even one with blinky lights to "pimp my Juniper." :-P

As for the SRX instead of M7i, the low end SRX's dont do logical systems, which is the feature I am after - support starts from the SRX3400 it seems, according to this document I am readin. You also need licenses to run them on SRX but not on the M series.

Im looking at co-lo'ing them at work in the comms room instead of home, so I dont think the fan noise will be an issue. That way I can run them all the time, with console access. Unfortunately only console access via the corporate console server on the corporate network, but hey, cant have everything.

This fan noise issue is one of the reason why I prefer to have SRX 100 or 210 instead of J series as home lab equipment. All Juniper JUNOS features are pretty much condensed into the same JUNOS code. So regardless of the appliance, you still have the same thing. As example, you could mock up L2VPN on SRX 100 unlike Cisco where you need to have ASR series to do so
