prepare for the CCIE R&S exam.

Subject: 2600 3600 3700 series routers [7:74812]
Group,
I'm currently studying for the CCIE lab exam. My lab consists of 2500 -
2600 series routers. My question is if there is a difference in IOS
features between the 3600s and the 3700s. I'm trying to decide if I need
some rack time playing around with the 3700s or if the 2600s and 3600s
will do everything the 3700s will do.
Thanks,
dave
