 &nbsp; The white paper probably covers this but if you run the &quot;show region&quot; command it will show you all the active memory regions your router is utilizing. If address 0x29762703 is not in the list (you'll need to know hex or use a hex-decimal converter) then you are having a software problem. Your IOS is trying to use non-existant memory. If address 0x29762703 is in the list then it is a hardware problem. Your IOS is trying to use bad memory.

Cisco 7204VXR error

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.
