12000 XR help

I have confussion.I want to learn about IOS-XR and want to buy a router that runs it. I read documentation that 12000 XR router and run XR software. My question is that does 12000 come in 2 flavors, 12000 and 12000 XR? which one should i get?

also when I look at the download center, i do not see any place where it says download code for 12000 XR, but i see a place where it days download XR software, but the file name has CRS-1 in it. can the same XR code run on 12000 XR as well.

Re: 12000 XR help


you can use the 12000 with regular IOS and also with XR IOS so I think this is the difference between 12000 and 12000 XR.

And you can use XR IOS on both platforms 12k and CRS-1 but if you want to use it on a 12k there are images which contain XR12000 in the name. For example I found this one when I was searching for software for the 12000 XR: XR12000-iosxr-3.6.1.tar

Re: 12000 XR help

Just make sure your 12k supports XR, but XR is XR, 3.6.1 is mature version so you can play around although you will not take advantage the fail-over if you don't have dual RP. What kind of 12k do you have? What kind of PRP do you have? What kind of LC do you have?
