I am looking for a free virtual lab where I can test various Cisco Configurations. I currently work for a company that does not have many Cisco boxes, or routers/switches of any vendor in lab, which forces me to plan very well and make changes to operational network without prior testing. Any help?

Do you use an incident/ticket tracking system?
I add my own favorite: Cheat Sheets on PacketLife.com has some very nice ones on network technology topics.
Cheat sheets are in PDF format. You are welcome to use and redistribute them as you please, so long as they remain intact and unmodified.
Currently there are six categories:
- Protocols: BGP, EIGRP, First Hop Redundancy, IEEE 802.11 Wireless, IEEE 802.1X, IPsec, IPv4 Multicast, IPv6, IS-IS, OSPF, Spanning Tree
- Applications: tcpdump, Wireshark Display Filters
- Reference: Common Ports, IP Access Lists, Subnetting
- Syntax: Markdown, MediaWiki
- Technologies: MPLS, Quality of Service, VLANs
- Miscellaneous: Cisco IOS Versions, Physical Terminations
Examples: Common Ports and IPv6 (links to PDF files)

If you can get your hands on an actual IOS load, you should check out the GNS3 Network simulator. With it you can build virtual routers running real versions of Cisco IOS and test out almost anything you need.
It's not all that easy to setup, but the documentation is very good and if you read it, you can do it.
