I have bought many Cisco routers and switches used for my labs and found that erasing the NVRAM was fine for what I wanted to do. My question is how far do you want to go with the routers and is this for a lab or are you going to be putting these into live Production?

We are selling our routers to others. I don't want others to get any configs out of these routers. Is deleting NVRAM enough?

In most cases yes NVRAM is enough. &nbsp;Now every make and model is different and what I would do is go to Cisco as they will explain the process for a particular model. &nbsp;The above reference from Soulja is excellent as well. &nbsp;But I would verify on Cisco first.

<div>
Now if you delete the NVRAM, There is a chance of getting the configs to load right back up if not done correctly, This is why I would go to the Cisco site. &nbsp;Better to be safe then sorry.

make sure you erase the vlan.dat file too.

Routers for resale.

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

Cisco PIX is a dedicated hardware firewall appliance; the Cisco Adaptive Security Appliance (ASA) is a firewall and anti-malware security appliance that provides unified threat management and protection the PIX does not. Other Cisco devices and systems include routers, switches, storage networking, wireless and the software and hardware for PIX Firewall Manager (PFM), PIX Device Manager (PDM) and Adaptive Security Device Manager (ASDM).
