ISR4000 Series Routers are Going End of Sale

In 2022, Cisco announced its ISR4000 Series is going End of Sale.

A product EoS, such as that of the Cisco ISR4000 series, means the manufacturer will no longer produce or sell that product. EoS announcements can cause concern for customers who rely on that product, as it may become difficult and expensive to obtain replacement or spare parts.

As you start considering your game plan for your current ISR4000 routers, there are other options you should consider.

The easiest path is to take what Cisco is suggesting, which is to replace your ISR4000 routers with the Catalyst 8200s or Catalyst 8300s (based on specific ISR4000 product part number). But we know you’re most likely running a product that can last for another 3 to 5 years, so why upgrade and spend your limited budget when it’s not yet necessary?

That’s where Curvature comes in.
