Cisco 4000 Series Integrated Services Routers (ISR 4000) vs Juniper Enterprise Routers

• Easy to use, simple to operate, highly predictable. IOS/IOS-XE is well known and there is a virtually limitless pool of engineers who know this platform and if not having direct experience, can apply knowledge from other IOS/IOS-XE with very little adjustment.
• Extremely flexible due to wide variety of interfaces. NIM and SM-X provide a great deal options: TDM, E&M, FXO, FXS, switches and servers are all options.

• We have had several times where we purchased assets and needed to add a remote site quickly for new staff to work. This is very quick to spin up and provides agility to business demands
• Allows for agility to failover network access when primary Internet services fail. We have near 100% uptime due to the ISR configuration we use. Even in the most remote locations.
• Since we adopted Cisco 4000 Series Integrated Services Routers (ISR 4000) as our de facto WAN hardware, we have cookie-cuttered our WAN infrastructure, which makes it easy to manage, upgrade, and alter with minimal impact to users and IT.
