Overall Satisfaction with Cisco 1000 Series Aggregation Services Routers (ASR 1000)

We deployed a few Cisco 1000 Series Aggregation Services Routers across multiple data centers and office as high-performance edge and WAN aggregation routers. They serve as critical components for our services which we provide to our customers. We run full BGP feed from IP-Transits with RPKI, ROA and also connects to multiple IXs. We also run ACLs for secure and compliant edge routing.

Pros

  • MPLS traffic engineering and segment routing
  • Large-scale & redundant pathing using BGP/OSPF
  • ACLs for secure access control
  • RPKI

Cons

  • Commit & Rollback
  • Unified OS using IOS-XR just like ASR9K
  • ASR1006 should be calling 1004
  • Route-processor shouldn't be counting towards number of line card
  • Improving deployment time
  • Enhancing network uptime and security requirements
  • Simplifying day-to-day operations and avoided significant downtime costs
As I have been using them through out my career, Cisco 1000 Series Aggregation Services Routers is very stable, with robust hardware and software redundancy. This reduces downtime and ensures high availability for mission-critical applications and services where we enabled multiple services, such as BGP, OSPF, ACLs, NAT & IPsec to connect to cloud providers over the internet.
  • Cisco 9000 Series Aggregation Services Routers (ASR 9000)
I would choose Cisco 1000 Series Aggregation Services Routers for enterprise WAN edge, branch aggregation, SD-WAN, and mid-sized service provider roles due to their high throughput, Integrated services(firewall, NAT, VPN), low power consumption and cooling, smaller size, and IOS-XE that supports programmability and automation. They are really dependable and easy to manage, deploy, operate and scale.

Would you buy Cisco 1000 Series Aggregation Services Routers (ASR 1000) again?

Yes

Based on my past and current experiences as a network engineer, they serve and run really well and also simplify our setup where we used them as edge or border or internet gateway routers. And also we used them as Data Center Interconnect, terminating dark fibers using LR or ZR SFP+. Even though they are well suited for enterprise network, there may still be some room for improvement with SRv6.
