CSR1000v

gorebrush

You would be right.

IOSXE is IOS but runs on top of Linux entirely.

It is very fast to work with and shouldn't have the quirks IOU has. For training I think this will do it. You can get IOS XRv too.

Just bashed out 10 routers, each is consuming 384Mb bear in mind this is running on HP Compaq Elite 8300 SFF PC with ESXi 5.1.0 and i3-3220 / 8GB of RAM. So far so good, using 3.6GB and barely any CPU consumed. This might be better alternative to running CSR for INE workbooks. VM itself is aroud 40Mb :P

gorebrush

On 32Gb RAM I could stand up a 100 of those!

deth1k

Easy tiger yes you could almost 100 but very many to say the least
Testing IOS for stability, looks very solid with INE topology replicated and basic configs loaded. Could be a very good alternative to CSR for those with desktops or low on RAM and tight on spending :P

deth1k

p.s: this thing boots fast, and i mean very fast. very similar to IOU, could be another consideration for impatient ones

gorebrush

Well 100 is slightly overkill but would make for a fun lab.... I think I will stick with CSR - once up and running its fast enough and the configs from INE are written to suit. There are a lot of initial config files too.

I so need a copy of that

networkjutsu

I want a copy too! What's the difference between the interfaces of CSR1000v and the IOSv? Just concern about the initial config.

In your experience with CML is it as buggy as IOU has been for people?

deth1k

Hmm I don't get why people are complaining about IOL being buggy, as long as you use same image Cisco use in their 360 rack rentals then you are set to go. In terms of IOSv, you can get it here :

https://developer.cisco.com/site/networking/one/onepk/sdk-and-docs/all-in-one-vm/index.gsp

It's very stable and resource consumption is similar to IOL with less bugs

gorebrush

What IOS is in the 360?

I grabbed IOSv - I like it a lot. Ran 10 instances without batting an eyelid and I stood up a DMVPN topology very quickly.

deth1k

I'll be going through full 360 lab tomorrow so will tell ya then Yes, IOSv looks very promissing it is ripped out of demo VIRL after all

gorebrush

Ahhh I wonder where it originated from.

fredrikjj

IOSv is extracted from the onePK Ubuntu development VM.

IOSv seems to run fine as a Qemu guest in GNS3 too.

Well I appear to be running 15 of these CSR's quite happily on my ESX server.

Using 10GB of swap. I've ordered 16GB more RAM to counter that and then I think I can get up to the 20 required for the labbing.

If I can do that successfully, I'll consider selling off some kit.

Hi Gore,

Do you think I'd be able to lab effectively with 20 routers using CSR1000V on my home workstation which is an i7-3550 Ivy Bridge CPU, 32GB of DDR3-1600 RAM, and an Intel 320 SSD w/ 64GB I can set aside strictly for this if needed? Will swapping to the SSD be a problem at all? I am looking for something I'll be happy with long-term here, but if I can find a way to leverage my workstation and save myself from buying a server I'd prefer to do that.

How much ACTIVE memory do you think 20 tuned routers would use? Will the remainder, swapped memory be fast enough with this SSD?

Thanks,

Chris

gorebrush

From my experience, anything past 13-14 routers started introducing swapping. Bear in mind I was running this on an ESXi server, so your host OS will require a bit more RAM to run for itself, so you may find that this number is more like 11-12. However, when you look at the performance counters in ESX - the "active" memory can drop to only a few GB of RAM - despite having like 25GB provisioned to it for 10 routers.

Apparently swapping to SSD shouldn't be too detrimental. If I were you I'd grab IOSv - that only needs 384MB of RAM per instance. However, I am not sure how stable it is. I tried it the other night and it seemed to run just fine.

I'll probably stick with CSR1000v myself as this is a full production router and I'd have more confidence using that than using IOSv which is essentially a demo of CML/VIRL.

The best thing to do is just to try it - that's the only way you'll know for sure

Are their any guides for building topologies with IOSv? I'm mostly wondering how simple it is to setup and use.

gorebrush

On ESXi it's just a case of connecting all the IOSv instances to a vSwitch and setting the trunk on that vSwitch to "All (4095)". All the routers then connect to each other using subinterfaces on ethernet anyways.

deth1k

don't forget to enable promiscuous mode on the vSwitch this will pass CDP etc. I'm planning on using IOSv although it's labeled as "demo" at the end of the day it's fully functioning router withot any limitations. When CML does come out it will be same IOSv relese with "this is demo verion" removed out of "sh ver" My build is already setup for INE when they fully update their v5 workbooks, otherwise it's very pleasant to use / has a better feel to it over IOL :P

I tried to use VirtualBox on Win7 to create the VMs from the IOSv vmkd file but they would not boot and run. I could see the boot screen asking me to boot into IOSv, but then the VM would crash. If I made them 64-bit linux OS they crashed my computer. Looks like I will have to use ESXi.

spiderjericho

I haven't really kept up with the onepk demo but I think Jack Ace is asking how to extract the IOSv from the demo.

i downloaded the demo and I can see where the confusion is.

I downloaded the demo and I found the ova file the demo uses for IOSv. I tried to import that into virtualbox, but it gave me an error stating it failed to import the appliance, unknown resource type 7 in hardware item line 60. I booted the IOSv routers fine inside the demo so I figured maybe the OVA file just wasn't compatible with virtualbox. I then tried to create my own VM using the vmdk file inside the OVA file and that VM would initially boot, but then crash. It looks like something isn't compatible with virutalbox, Win7 or my hardware, I'm not sure which.

pitviper

If you’re not looking to run a ton of routers you can fire it up in GNS3 (Qemu guest). Seems to work fine in VM Workstation though it’s a PITA to create virtual serial ports. Runs like a champ in ESX.

Could you tell him how to run extract it and run it in the VMware products?

And is player not free anymore?

That is exactly the process I used for VirtualBox, and the VM crashed. I planned to give it a shot in a free trial of VMworkstation and GNS3 tonight. I will let you know how those work.

Update - got it to work in GNS3 pretty easily. VMworkstation looks like it might work if I can figure out how to console to the VM. At least it didn't crash like it did in VirtualBox.

Update 2 - GNS3 seems to work okay for this. It hits the CPU hard when you boot the VMs and it takes a few minutes to get them all booted. I booted 7 hosts at the same time and it pegged one of my CPU cores at 100% for a good 15 minutes to get all 7 loaded.

Update 3 - I got the console access working in VMworkstation, but the pipe appears to not be connecting to the console port because I keep getting the error no password set when connecting.
