It is very well suited to act as your aggregator / core switch for mid to large facilities. it is flexible enough to really be useable in small environments but costs may hinder that. It has redundancy of power and management blades that does add a lot of peace of mind and security. Really the only reason you would not use a 9000 series is frankly cost and/or real requirements for performance. They have several versions of this model, plus they have an entire set of lines that can accommodate nearly as much as the 9000. Less demand or less of a budget can weigh in the decision to select this particular model.
It's best suited for small offices 10-25 users. Any more and its best to move away to a more higher tier. It will be less appropriate for a mid level company with a large staff. It's best for a small business with a limited budget and less strenuous security functionality.
[The] upgrade process [is] 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 configuration.
[There are] 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.
[It has] 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.
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.
The features are good. The support is good. The resources to deploy, manage, and operate it are good. Customer's feedback and testimonials are good. The updates in terms of zero day vulnerabilities are good and timely. But, I still give an 8 out of 10 because I think the pricing, licensing, and GUI can be improved more.
When we are integrating the ASR9000 router with other devices then there should be the same device that can cater to the throughput. We can use the Cisco 9600 Switch which can be easily integrated and can handle the speed in terms of uplinks 40G can be handled. Adding to this Cisco DNA Center can be integrated to do the automation and monitoring purposes.
Cisco's power really stems from its brand reputation and honestly not much else. No one ever got fired for deploying Cisco, and that's why it stands out. The Cisco Small Business RV Series is no exception there; the unit is built well and does the job. However, much more powerful alternatives for routers are out there—the biggest competitor being Ubiquiti. The UniFi routers are significantly more powerful in all regards, including routing speed, IPS/IDS speeds, and VPN functionality. Support for those is admittedly rather lackluster though, so if your network is critical, you are effectively self-insuring your equipment. For some that may be fine, but for others, that risk of extended downtime is just not worth it.
We didn't need to buy new devices when we were increasing backbone capacity from 1G to 10G.
Due to the modular nature of the software, when there is an issue with any running services, we need not reboot the whole device which affects all clients and availability.
