Choosing the Best Cisco Enterprise Routers

To choose the best enterprise router from Cisco, you need to consider certain features of the router.

Types of Network Routers

Cisco Systems offers a number of network routers on their Enterprise range of products, and you really know exactly what you are looking for in a Cisco Enterprise network router. There are six main categories of Enterprise routers by Cisco, as shown above. These are:

Cisco Integrated Services/ Branch Routers

The integrated service routers by Cisco are also called branch routers, and they are designed to enhance Cisco’s range of the branch office routers thanks to their integration of a multiple services system into one platform. The integrated services routers are an improvement of the previous hardware that called for the purchase of extra hardware for the integration. Routers in this category include the CISCO 800 Series ISR, CISCO 4000 Series ISRM, and the CISCO Meraki MX.

Cisco Internet Edge Routers

Internet edge routers refer to a special kind of routers that are often placed at network boundaries, a design placement feature that results in an empowered campus network system capable of associating with external networks. The edge routers are often utilized within the web and WAN. The CISCO ASR 9000 Series and the CISCO ASR 1000 Series are two of the main router series in this category.

Cisco WAN Aggregation Routers

These routers boast a superior/ high-performance IP, and it also features scalable plus customized IP services all at your network’s edge. Routers in this category include the CISCO NCS 5000 Series, CISCO NCS 5500 Series, and the CISCO ASR 1000 Series.

CISCO Service Provider Core Router Series

These routers are also called Provider Cores routers, and they are ideal for consistent communication with your enterprise’s operations. It also allows for effortless scaling of your business enterprise from a simple single chassis form factor into one enormous multi-chassis system.

There are three main router series under this category, and they include the CISCO NCS 5500, CISCO NCS 6000, and the CISCO ASR 9000 Series.

Cisco Integrated Services Virtual Router

These integrated virtual routers are a part of Cisco’s new Borderless Network Architecture, which is aimed at empowering business innovation and growth, specifically in remote sites. There are two main routers that fall in this category – the CISCO CSR 1000v and the CISCO IOS XRv 9000.

CISCO Industrial Routers

These are integrated industrial routers. They are robust and compact and ideal for use in harsh environments. They include the CISCO 800 Series Industrial Integrated Services Router, the CISCO 900 Series Industrial router, the CISCO 1000 Series Connected Grid Routers, the CISCO 2000 Series Connected Grid Routers, and the CISCO 500 Series WPAN Industrial Routers.

Features and Benefits

It’s not enough to know about the main categories and types of Cisco enterprise routers. You need to know what features make an excellent Cisco router. Here are some of the most important considerations that you need to keep in mind.


Make sure that the enterprise router you settle on offers the best authentication features, along with segmentation and the strongest encryptions for the protection of your data, applications, and users. The protection needs to span from your WAN edge to the Cloud.


Cisco enterprise routers are either Cisco SD-WAN or No SD-WAN.

Target deployments

Are you looking for a router with WAN aggregation, Branch, Edge, or Machine-to-Machine target deployments? There also are other types of deployments, including virtual deployments, service providers, and small businesses.

Speed/ Encryption Throughput

Speed is also important, but you need to look at the speed of the router in terms of the maximum internet MIX encryption throughput. Generally, enterprise routers will have variable speed setups ranging from a minimum of 50Mbps IPsec to 45Gbps IPsec.

To choose the best router for your organization, you need to know the average speed from your office’s internet connection. With download speeds measured in Mbps, and most and internet connections offering variable speeds from 3-7Mbps, others will run at 2Mbps or lower while others will offer higher speeds. So, first, take your needs into consideration. ADSL2 and ADSL2+ routers are some of the fastest routers, but if you need speeds upwards of 50Mbps (minimum), it would be a good idea to settle for the Fiber-based routers (most of the enterprise routers fall in this category).

Router management

Look for a router with a simple GUI for easy network management. On the same note, you might want to opt for a router whose company offers excellent support.

The other features you need to keep in mind include:

  • Scalability
  • Connectivity choices
  • Number of users that can use the router seamlessly.
  • Security level, Firewalls, and presence of business-grade VPNs
  • IP Phone networks
  • WAN redundancy


What is Cisco SD-WAN?

Cisco’s SD-WAN refers to a secure, cloud-scale architecture that is open, scalable, and programmable. It’s easy to establish an SD-WAN overlay fabric in your network through Cisco’s vManage console, and you can use the fabric overlay to connect branches, data centers, colocation facilities, and campuses, all in a bid to improve efficiency, network security, and speed.

What is a Gateway-to-Gateway VPN?

This is the VPN connection that allows you to securely connect two routers to each other while allowing the router client on one end to appear as part of the overall network with the second router on the other end. Thanks to the setup of the routers, resources, and data will be securely and easily shared over the internet. This VPN system is crucial for enterprises, but you need to make sure that the configuration is done correctly on both routers.

What is IPsec?

IP stands for “Internet Protocol” while “Sec” represents Secure.

IPsec refers to a group of specific protocols that allow for the setup of encrypted network connections between your devices. The protocols facilitate the secure transmission of data over public networks. To enhance the security of the networks, IPsec is set up along with VPNs where it works by encrypting IP packets while also authenticating sources of the data packets.


If you are looking for the best Enterprise Cisco router, the five routers reviewed above are some of the best for business/ industrial use. They are robust, reliable, and efficient.
