I finally got my smart serial cross-cable (CAB-SS-2626X) when I visited my mom in New York a couple of months back. With these cables, I can emulate a Frame Relay cloud and use serial interfaces for WAN connection in my lab routers.
I was doing some EIGRP labs for my ROUTE studies and configured my 2811 router as a Frame Relay Switch. I was also able to do a Tool Command Language (TCL) script on a Cisco router, which in my opinion is the coolest feature I've learned in CCNP ROUTE.
