My advice for those looking into ExtremeRouting is: right now all switch manufacturers are backed up for months. If you're looking to implement quickly, I would say shop around a bit because it might be difficult.

I think that all the devices included in Avaya fall under Extreme Networks currently. I am not sure how much Extreme Networks has changed ExtremeRouting, but I think it is in a better condition than Avaya. The support, software resiliency, and software stability are areas of concern where improvements are required.

The product could be improved by including the latest protocols to match the other vendor standards because some of the latest protocols are unavailable. So when we mix this device with other companies and vendors like 48 or Cisco, we have issues because ExtremeRouting uses more of these proprietary protocols. Hence, they can improve by adding the latest protocols to the data.

One area for improvement with ExtremeRouting is the need for more accessible and comprehensive training. It is crucial because the product requires a good amount of technical expertise for effective support and operation. In comparison to competitors like Cisco, where many people are trained, having free and thorough technical training for ExtremeRouting would be beneficial. 
I would like to see Extreme Networks expand its offerings to include industrial equipment for sectors like mining and aviation.

Overall, we've had a lot of issues with the solution. It should operate more like Cisco's Nexus 9300. It needs a lot of work.

Due to the issues we've been having, we plan on replacing the device completely.

The solution is far too unstable. It's completely unreliable.

We are concerned with how the solution will evolve to the next generation of Contact Center.

It's not evolving as quickly as we would like it to. We want to move to the next generation by the next quarter, but they are not ready yet.
