I have anumber of 1921 routers deployed and am looking into using PfR. I'm having a bit of a headache working out if my 1921s support PfR and what IOS version/licenses I would need.
At the moment I have most running Version 15.2(4)M3 and some new ones running 15.4(3)M2.
PfR or OER commands are not recognised.
Will my 1921s support PfR in any shape or form?

You need to have all of your PfR routers at or above 15.4(3)M as well as a Data license. This version of code and above supports PfR version 3 and below it supports version 2. They are not compatible. Before you put this into production, I would HIGHLY recommended working with it in a lab environment and some traffic generators. Once PfR starts redirecting traffic, you need to know how to tune it and troubleshoot it. A good place to start is the PfR docwiki:

Also, monitor router utilization as you add more features such as NBARv2, etc... V3 runs on the ISR G2s, but the ISR 4Ks have the power to fully utilize the IWAN features.

Hi Daniel,
I think you would need DATA license on router. What is the current license on the router?
Cheers

For License
A. Refer to Figure 3.
Figure 3. New Cisco ISR G2 Simplified Feature Sets (PfR is within the DATA Package)
For Hardware/IOS see below
A. Refer to Figure 1.

Hope this helps.

I haven't tried PfR on a 19xx (or any other recent series ISR), but on the 28xx series, you needed more than IP Base. So, my guess would be PfR might require some advanced feature set and/or specific license. It's also possible, though, it might not be supported on something low-end like the 19xx series (one of your questions). Unfortunately, sorry I couldn't be more helpful. Someone else may answer yet.

Thanks everyone,
That seems to be correct. I have loaded a trial DATA license onto a spare 1921 running 15.4(3)M and the command are there. Now for some time creating a lab to see if I can do what I want to achieve.
