Cisco’s 4000 router family is a serious upgrade from the older 1900/2900/3900 router families.

Last month it was Catalyst 9000 switches, and this month its routers. Yes, my project engineering staff have had a surprising amount of inquiries regarding routers.

Routers vital to enterprise networks

When looking at distribution for an enterprise network, well-planned routing is the key to success. Routers can be absolutely vital for networks, as they connect a large amount of worksites within one large, umbrella-like network. At the enterprise level, they provide redundant paths, connect ISPs, and can translate data between different media.

In addition to routing packets to the right place, routers will select alternate routes when a link is compromised or traffic is heavy. Routers, Cisco routers in particular, work as a default gateway. And Cisco’s 4000 router family, while it has been out for a while, is worth another look.

Cisco’s 4000 router family is a serious upgrade from the older 1900/2900/3900 families — but not so different that they blow your mind.

What’s new in the Cisco 4000 router series?

The Cisco 4000 series has the following features:

  • Broad range of performance levels – from 35 Mbps to 2 Gbps
  • All but the smallest 4221 model have OIR (online insertion and removal) capability for the NIMs
  • Significant increase in max RAM (up to 16 gig on some models)
  • Utilize the same IOS software feature sets/licensing model as the older ISR G2s

Here’s the list of available models from Cisco:

And here’s a table that shows performance levels, port, and module count:

Notice the row labelled “aggregate throughput”? There are two performance numbers per router – Cisco has taken the performance licenses originally found on their mighty ASR router line and adapted them. If you purchase any one of these routers, they will come standard with the lower of the two performance numbers. Later on as your requirements grow, you can purchase a performance upgrade license from Cisco and voila! Your router now is faster.

These routers have many other features and capabilities. Take a look at the links for more helpful information:
