Very good but not perfect

Cisco ASR 9000 Are used mainly for IPMPLS core (PE Function) deployment at our utilities and service providers costumers. . Mainly packet switching and MPLS function. Perfect performance so far, despite being in the market for a long time, it is a trustfully platform.

Yes, compatibility is important and it turns out teams job easier, we can have faster deployment, services are ready faster and we have faster ROI. We don't need to loose time on compatibility problems, for which sometimes is difficult to find information and troubleshoot.

Of course, we rely on Cisco product to trust our network are safe from star. Cisco is a trustworthy company, with good presence and good support teams around Europe which makes us feel confortable deploying Cisco solutions, if they fit the customer needs. Security is more and more important, so having firewall capabilities at the routers is very important.

Unfortunately, Cisco Routers (ASR900) don't have legacy interfaces anymore, and for that reason sometimes we need to choose to go with Nokia routers for utilities substation environment. Cisco NCS familyI doesnt support legacy interface and most models are not compliant with IEC 61850, making our job hard to chose Cisco for this environment.
