As most of you I came from the traditional side of telephony having started working on Tie and Executone in the late 80s. Also as most of you know the industry has dramatically changed. I could see it coming about five years ago and decided to update my skill set and get involved with engineering and designing converged infrastructures. I rarely touch the traditional stuff any more but understand many of you want to "play around" with some routers and switches and either do not know where to start, do not have the money, or for a variety of reasons have not got involved with this side of technology. I have acquired propably close to 20 Cisco devices and have recently purchased an Access server and was going to setup the equipment to use "free of charge" if I got enough interest in the project. I would do everything VIA TACACS+ and would email everyone the authentication information, as well as the LAB topology. My first lab will have 3 routers an IOS switch and a CatOS switch. The routers will be running HDLC between 1 and 2 and frame-relay between two and three. All will have ethernet and TFTP enabled. Please let me know if there is any interest in such a project and I will work on it over the next couple weeks.
Thanks, I am always willing to learn more about how things work.
Ditto here, never can seem to keep up,but the wheels are still turning
I'd like to learn Cisco, but they're too expensive for my budget.
I have been working towards my CCNA...did the first 2 parts in my last 2 years of HS...just graduated and am going to Toledo to study computer network adminstration. I have 2-2501 and 1-1601 routers at home. Count me in for this virtual lab...
CCNA is next on my agenda. I did get an MCSE but who cares. I started with 1a2, Tie and Toshiba. You can't just tread water in this business, you need to swim.
I haven't completed my bachelor's because the only class I can't stand sitting through is Inter-networking, and the professor chose to use Cisco as the basis of all knowledge about the internet.... It didn't help that our classroom lab never worked right, and all 20 students were trying to log into one set of routers.... I took the class twice, but nothing changed. I was always searching for a good Cisco lab simulator. They finally got one out a couple years ago - 4 years too late.
Ok I can see the interest is there so I will have the lab setup this weekend. If anyone wants access please send me a private email with a username and password you would like to us and I will create a TACACS+ login for you. Please be patient will I work all of the bugs out...
The lab is now up. I only have one running because I am having some difficulty partioning the access server, but it is functional. You can view the Visio at
https://webpages.charter.net/gjcave/cavelab.gif Please email me to be added to TACACS.

I had an old email up if you want access please email me again, I fixed the email address.
Providing free of charge i think everyone would appreciate that. However, boson.com, has great software simulators at very reasonable prices.
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
