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.
MikroTik is suited for large companies that require advanced distributions in terms of contracted bandwidth, and in the same way, allows a single device to specify filtering and firewall rules without acquiring an additional device. There is a range for small companies which is more economical and less robust, but in case it's not necessary, such a strict control over the data consumption of the company is not a feasible solution.
[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.
Some of the wiki articles have not been updated or are not accurate enough. We spent a couple of days trying to find an example of implementing a mobile IPSec client solution. But once this has been implemented, it has been solid (always worked). A bigger community would help, and I am finding it hard to find the time to contribute to these articles.
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.
There is no SOC, NOC, where you can contact to try to resolve any difficulties. The problems that these devices have are solved largely through the community, with workaround alternatives, or if the support team responds to a request, the response times are too high for the current needs of technological communications.
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 Routers are one of the best in the market, however they are also very expensive and not suitable for a small deployment or any deployment which requires just a couple of routers. MikroTik on the other hand are less expensive and provides many features that you require for a small scale deployment. they fit in with the budget and do what you need them to.
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.
