I never really caught this until a few minutes ago. While working on lab 7a
in the v3 Sec on proctor lab, my R2 booted with 12.4-3a. Everything seemed
fine, but when going through the proctor guide on RFC3330 filtering they use
Object Groups. I was excited that this had been added into IOS, but
couldn't get it to work. Upon further digging, I found that the IOS must be
at 12.4.20T in order to use this. There is a 12.4.22T on the flash of the
router? I guess my question is, is this one of those things that we should
check when we sit down for the real lab? I assume yes.
