I'm looking to study for the CCNA security, and eventually CCSP. I am familiar with the PIX/ASA command set the FWSM modules and to a lesser extent the IPS devices and mondules. However the IINS blueprint only mentions routers.
How easy will it be to transfer my knowledge to this hardware? I have access to a number of old (2600) routers, will these be sufficient for a lab environment, and what image would I need to run for the feature sets used on the exam?
