Cisco 900 Series Integrated Services Routers (ISR)

No problems with any of the Cisco 900 Series [Integrated Services Routers] (ISR) platform features within the enterprise environment. Because these devices are running a version of IOS XE as opposed to traditional IOS, some of the more 'basic' configurations can become more complex. In the end the 900 series is still able to provide the required functionality, but there is a learning curve.

Cisco 9000 Series Aggregation Services Routers (ASR 9000)

Any large enterprise with large throughput requirements for their business-critical infrastructure should use the ASR series routers without exception. The licensing cost might hit your pocket hard, but with the exceptional performance and reliability that the ASR series offers, it is easily the best option available in the market. It is the "tried and tested" router. Don't think twice, just go for it!

Pros

Cisco 900 Series Integrated Services Routers (ISR)

  • Works great as a full-featured but small router for remote sites
  • Can handle more traffic than it even advertises!
  • Well priced option for smaller or less critical sites

  • Layer 3 multicast. It handles the additional load of multicast without issues. Other platforms we have used have had over-subscription issues.
  • We've used several MPLS features such as pseudowire using bridge-domains as well as xconnects. Plenty of features to solve any design problem.
  • IOS XR. I just love operating in IOS XR. Solve so many problems that exist in IOS.

  • Pay as you grow model of licensing, but a pain to implement
  • Service impacting license application
  • Configuration complexity

Cisco 9000 Series Aggregation Services Routers (ASR 9000)

  • Upgrade process overly complicated compared to NX-OS or IOS: new images and the current configuration need to be compiled into "golden IOS's". If you don't include the configuration, you will have a clean device with no config.
  • Major bugs in every release. We have had to cycle through all of our routers 3 times in the last year for updates due to show-stopping bugs that did not come to light until after the changes were made in production.
  • Terrible documentation. You have to mine their site to get to any documentation for recent versions of IOS-XR. If you make the leap from 32-bit cXR to 64-bit eXR then the documentation is more-or-less non-existent. Due to the internal architecture of hardware itself, technical specs can change from software version to software version, so don't expect any sort of firm scalability numbers. You'll have to rely on your sales engineer for that.

Cisco 9000 Series Aggregation Services Routers (ASR 9000) 6.5
Based on 5 answers
In some ways, the platform is a big improvement over our previous IOS and NX-OS devices:
  • They offer version-controlled configuration staging/commits.
  • They have a robust portfolio of network protocols and features even beyond datacenter devices.
  • Due to the use of NPUs instead of relying entirely on ASICs for forwarding, new versions of the software are able to improve hardware performance and capacity.
Unfortunately, I have run into more bugs on IOS-XR than I ever did on IOS or even NX-OS (which has a shocking number of bugs of its own) and you have to be a licensing guru to get your order right the first time.

Alternatives Considered

Cisco 900 Series Integrated Services Routers (ISR)

Cisco Catalyst Switches are technically faster and easier to deploy, but don't provide the same flexibility when it comes to 10Gbps services or advanced routing. There are corner cases where having IOS XE on the 900 series ISRs provides the functionality required for complex applications where the Catalyst can not. Having the option to scale the number of active ports on the 900 series ISR helps in keeping costs at an appropriate level.

Each has its own strengths and weaknesses. Juniper was more security/less routing and Cisco was more routing/less security. Redback was Ericsson which is easy when creating VRFs known as contexts. When doing show command it would give you all the information within that context. In Cisco you need to perform 3 or more commands to get the same info.

Return on Investment

Cisco 900 Series Integrated Services Routers (ISR)

  • Lots of money saved in downgrading from less useful and older full-sized routers at small sites
  • Time saved having to learn new commands (web GUI works great)
  • Saves time training staff to manage them

  • Higher reliability has significantly reduced the need for manual intervention
  • Lower downtime ensures better top-line figures
  • Although it may be difficult to quantify, I am certain that the higher performance does have an impact (maybe indirectly) on other business functions. High-performance routers are like the oil that keeps an engine running smoothly.
