Recently I've migrated the Free CCNA Workbook website to the new Stub Area Networking website located at
Stub Area CCNA WorkbookI've done this so in the near future I can also write the CCNP - ROUTE, SWITCH and TSHOOT Workbooks.
I have also made available to the general public the
Stub Lab for those individuals who would like to have access to physical hardware. Access to this lab is completely free; just sign up and reserve a lab session. The lab currently has two Catalyst 3550-24's and a 2950G-24 which will soon be replaced by a Cisco 3560-24TS-S.
