It is a highly scalable solution. We mainly use it for 100 gig connectivity. It also allows for frequent manipulation or configuration, but we never use those features.
What is most valuable?
For how long have I used the solution?
We have been using this solution for over five years.
What do I think about the stability of the solution?
It is comparatively stable.
What do I think about the scalability of the solution?
It is a scalable solution.
How are customer service and support?
The technical support is good.
Which solution did I use previously and why did I switch?
We used the MX Series instead of the PTX. We were expanding to a 100 gig backbone, so we had to move to PTX as a product.
How was the initial setup?
We deployed this solution using a template, so we did not use any default feature of Juniper.
What's my experience with pricing, setup cost, and licensing?
We are a global partner, so we have a good discount from Juniper. However, I am unsure about the precise cost because I am not a technical expert.
What other advice do I have?
I rate this solution an eight out of ten. Regarding advice, I would recommend PTX Series Routers to those who want 100 gig connectivity. It would be good if they added a redundant routing engine.
