Core and data center applications are the strengths of Arista products. The distribution layer is also a good fit. For the access layer, it would be more of a niche product.
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.
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.
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.
I have used the Catalyst 6500 series in the past. From my point of view, the Arista surpasses the Catalyst on just about every front. Originally we were planning on implementing the Nexus 7000/7700 series switches for our core. Though a little more feature rich, it did not provide features we needed that the Arista did. The Nexus also was a confusing and complex platform to work with. Also, the Nexus was a significantly more expensive solution. Although very happy with the Arista switches we may evaluate the Aruba HPE 8400 chassis-based switches along with Arista switches in the future.
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.
