Ok I guess a few of you were having difficulty getting started with my lab. I have put a very simple config on the devices and configured basic dynamic routing. I am posting the configs as a baseline so please change them and play around with them, but here they are.

It also seems people were having difficulty navigating the rotary reverse telnet groups. Here is another direct access methed you may find a bit simpler.
1.1.1.1 2001 = Router 1
1.1.1.1 2002 = Router 2
1.1.1.1 2003 = Router 3
CaveLab#1.1.1.1 2003
Open
The above example sends you to r3.
If all is correct R1s routing table should look like this:
R1#sh ip route
Codes: C - connected, S - static, I - IGRP, R - RIP, M - mobile, B - BGP
D - EIGRP, EX - EIGRP external, O - OSPF, IA - OSPF inter area
N1 - OSPF NSSA external type 1, N2 - OSPF NSSA external type 2
E1 - OSPF external type 1, E2 - OSPF external type 2, E - EGP
i - IS-IS, L1 - IS-IS level-1, L2 - IS-IS level-2, ia - IS-IS inter area
* - candidate default, U - per-user static route, o - ODR
P - periodic downloaded static route
Gateway of last resort is not set
172.16.0.0/16 is variably subnetted, 4 subnets, 2 masks
C 172.16.255.0/30 is directly connected, Serial0
D 172.16.255.4/30 [90/2195456] via 172.16.1.2, 00:14:01, Ethernet0
C 172.16.1.0/24 is directly connected, Ethernet0
D 172.16.2.0/24 [90/307200] via 172.16.1.2, 00:14:01, Ethernet0
