Juniper Networks describes their MX series as a robust portfolio of SDN-enabled routing platforms that provide system capacity, density, security, and performance with longevity. MX Series routers support digital transformation for service providers, cloud operators, and enterprises.
I think the Juniper MX series is a fantastic option for data center connectivity and places that aren't very high touch, but need good reliability and uptime. These switches are a bit more difficult to use day to day, but their reliability and robustness make them a great fit for data centers.
Juniper (Junos) and interoperability. Junos is so powerful as a troubleshooting tool and also as a configuration tool. We had test and roll back configurations which is very helpful. Being able to link to over vendors equipment and extend features is very nice to have.
We preferred Juniper over Cisco for our WAN/Internet routing needs for a number of reasons. First was the price, the Juniper offering was much more competitive than Cisco's. Secondly, was feature set, Juniper's implementation of routing protocols, routing tables, and forwarding options are better thought-out than Cisco's (not to mention Juniper's longstanding use of commit/confirm/rollback features, which Cisco has only started to use recently, and only on some of their products).
