These labs are designed to prepare you for the troubleshooting section of the CCNA exam. These labs will test you on:

NAT
STP
VLANs
EIGRP
OSPF
ACLs
DHCP

Please follow the instructions carefully for each lab. The broken configs must be loaded into the running config of the routers and switches (if applicable). You log into the router and copy the relevant broken config into running-config:

Router#copy flash:[name]-confg run

example:

Router#copy flash:broken1-confg run

**DO NOT SAVE THE CONFIGS WHEN YOU FIX THE NETWORKS **

If you get stuck, please post on the CCNA forum stating which lab you can't fix plus any configs.
