Routing has supported carrier-grade services and has needed more affordable security options
The features of Juniper MX Series Routers that I find most useful are its nice scalability, redundant power supply, and routing engines. Redundancy is maintained in the router itself, including power redundancy and routing engine redundancy. The routers run mostly all the protocols required for the managed service provider, and security-wise, they also have good features, allowing us to provide IPSec VPN services from the routers. These are the basic, mostly used features that we are utilizing. For Deep Packet Inspection, Juniper MX Series Routers have firewall filters and commands related to routing engine protection, and then packet inspection features are configured. In traffic management with Juniper MX Series Routers, I leverage the policer, shapers, and quality of service parameters for traffic management. I also use OSPF traffic engineering features and MPLS-TE; these are a few features that I employ for traffic management.

Session-based routing has transformed branch failover and now optimizes application paths
Juniper Session Smart Router is a very good cloud integration router, with very strong application visibility, and WAN path optimization is also present. It has very good simplified branch connectivity, particularly strong automation and API support, and better SaaS performance. Session-based routing instead of tunnel-heavy architecture is one of the best features. Session-based routing and API support in Juniper Session Smart Router have helped me in my work. It helps in session-based routing changes from route-based packets only on destination IP to application session awareness. This can help with a better application experience, and voice or video traffic automatically takes the best WAN path based on latency, jitter, and packet loss. Faster failover occurs; instead of waiting for routing protocol convergence, sessions can dynamically move to healthier links. Additionally, there is improved SaaS performance. In terms of APIs, I have had a very good experience integrating it with automation platforms like Terraform and Ansible. It has reduced manual errors, and my team has been using the API to automate deployment and dozens of other tasks with branch SSR devices. Another feature I can think of regarding Juniper Session Smart Router is that there is no traditional overlay tunnel overhead in many scenarios, which is one of the best features. Dynamic path selection based on latency and jitter makes this one of the standout features.

Quotes from Members

We asked business professionals to review the solutions they use. Here are some excerpts of what they said:
 

Pros

"The most valuable feature is the standard routing protocol."
"The performance is good."
"Overall, this is a very good product."
"The solution is quite stable. We've found it to be very good. There aren't bugs, glitches, or crashes."
"From my experience in the ISP world, I think that Juniper Enterprise Routers are very good products."
"Overall, I find this to be a good product; the features are completely stable and customers are happy with their investment, although there is occasionally an issue with the reliability of certain modules."
"It is very stable and scalable."
"Juniper solutions are very flexible and very good."
"Customer service is very prompt."
"The solution is especially Session's smart, application-aware, AI-based."
"Juniper Session Smart Router has positively impacted my organization by achieving a 30% to 40% reduction in WAN cost, which means less reliance on MPLS, with a 40% faster failover with near-zero user impact during link issues, and 20% to 30% less time spent on troubleshooting, along with fewer outages due to dynamic path selection, which facilitates fast branch deployment."
"For telecom companies, I think zero-trust segmentation is the way to go because if you allow anything that you do not understand, then it becomes a problem."
"The best feature is the easiest way to deploy configuration and also back up them, and also to roll back quickly if there's an incident."
"Because we are talking directly to engineers in the US, the support is usually the best you can possibly get."
"Juniper Session Smart Router has positively impacted my organization because we have multi-cloud solutions that are extremely useful for our M365, Teams communication, Zoom communication, SAP applications, and Oracle-based applications."
"They provided us with a customized product according to our requirements."
 

Cons

"In terms of improvement, I would like for it to effectively protect against the broadcast storms, multicast storms, and DDoS attacks."
"The integration could be better. It was a difficult configuration with integration with other systems."
"One thing that the product can do better is clustering. Rather than just having two of them, it would help if there was one cluster to extend to more notes in the cluster itself."
"In terms of what could be improved, they could extend the software warranty to be for its lifetime, as well. At the moment, the software warranty is limited, I think to one year."
"The security features could be better."
"Juniper Enterprise Routers could improve by adding a graphical user interface (GUI). They do not have one."
"Juniper have addressed issues with the MX204, but it still has a limited number of interfaces. Ideally, it should support up to twenty or twenty-four interfaces to better serve smaller service providers. Additionally, the MX304 doesn't support subscriber management, also known as BNG, which I believe should be included."
"The Juniper technical support agents should have more technical and hardware knowledge of Juniper routers and switches."
"I found some weaknesses on their hardware. They are sometimes breaking very often."
"Juniper Session Smart Router could be better in several areas such as the steep learning curve because the session-based model is different from traditional networking."
"One area for improvement that I have observed is related to the VPN, where I frequently notice VPN flaps or disconnections between Juniper Session Smart Router and the SD-WAN hub device in the data center, which should be addressed to prevent users from experiencing any downtime."
"Juniper Session Smart Router can improve the integration for Wi-Fi devices and add additional Sassy deployments."
"Juniper Session Smart Router could improve its documentation to become more competitive. It has very little documentation, and you have to rely mainly so much on support to do something, which I feel should not be that way."
"Juniper Session Smart Router could be better in terms of software performance."
"The UI of the SSR conductor is the main part where improvements can be done. Today, for every configuration step, you have to do a series of clicks."
"Juniper Session Smart Router can be improved by simplifying onboarding for traditional network teams and providing better documentation for complex deployments, as well as improving the GUI for operational workflows and better migration tooling."
 

Pricing and Cost Advice

"I would rate the pricing model a seven out of ten, where one is cheap, and ten is expensive. It is not cheap."
"The pricing of Juniper MX Series Routers is okay compared to other technologies."
"The prices for Juniper MX Series Routers are reasonable."
"There is a license for this solution and the price is very competitive. The cost is less expensive than some competitors, such as Cisco. There are additional costs for support licenses."
"The solution is more expensive compared to other solutions."
"$300 to $400 is the hardware cost and for licensing cost, it may be around, for support and all, $100 per year."
"An additional license can be purchased for support of a next-generation firewall."
"We have to pay for the device and licensing. The support service requires additional costs."
"We are currently renegotiating the offer for the licenses and the license bundle model. The license for an ISP has to be different from the license for an end customer. This is something we are currently renegotiating with Juniper, but, of course, the pricing for the licensing is always an issue when you want to get more customers."
"It is a simple bandwidth-based license and the orchestration comes bundled with the solution by default."
