Overall Satisfaction with Cisco 9000 Series Aggregation Services Routers (ASR 9000)

It is basically used as a fully functional core router on the network. It has the capability to handle the amount of traffic going through it and is easily expandable as demand grows. In addition, due to its versatility, it is also being considered as a potential edge router for future expansion.
  • Easily expandable
  • Good port density
  • Still relatively new
  • Needs to be able to handle higher port density as the need for higher bandwidth demands grow
  • Software upgrades could be done more efficiently
  • Too many licenses for various features
  • It has offered better port density than previous devices.
  • It is fairly new device and offers the ability for future upgrades.
  • The architecture will not be retired any time soon.
We have mainly used the ASR9000s to take the place of older models and devices such as the GSR and CRS model routers. The GSRs have long been End Of Life and are no longer supported by Cisco. The CRS is a capable device but does not offer the versatility of the ASR family of routers.
Cisco 1000 Series Aggregation Services Routers (ASR 1000), Cisco 5000 Series Network Convergence System (NCS 5000), Cisco 5500 Series Network Convergence System (NCS 5500)
It is well suited as a large router in a data center handling extreme amounts of traffic. It offers room for expansion and upgrades. It does not work well as a customer premise device due to its size, power, requirements, and cost. There are other ASR models better suited for such cases.
