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

ASR 1000 is serving as WAN aggregation Router for termination of our external 10G links. Enabled with active active VRF lite BGP routing externally and internally.
  • Routing performance is good.
  • WAN aggregation supporting multiple Gig speeds.
  • Firewalling via ESP mode.
  • Hardware level QoS.
  • ESP offload support all major features to offload load from RP.
  • Multi port 40G and 100G cards.
  • Performance above 200Gbps is not possible.
  • SIP/SPA module is very costly.
  • BGP
  • PFR
  • Cisco Nonstop Forwarding
  • ISSU
  • Stateful Switchover
  • EtherChannels
  • Positive of ASR 1000 is its cost effectiveness as a WAN aggregation router providing 10G-100G interface limited by 200G performance.
  • As such there is no negative side, but if you need more then 200 Gbps performance then you need to change the Router, that's the only option.
For cloud network all these products complement each other to ensure HA reliability, optimized path, workload mobility, multi services, multi hypervisor support to service our workloads.

Evaluating Cisco 1000 Series Aggregation Services Routers (ASR 1000) and Competitors

Yes - Previously all our WAN link where directly connected to our DC Nexus 9500 switches. As part of Network moderinization we introduced ASR 1K in out Coud network to aggregate all external link.
  • Product Features
  • Product Usability
  • Product Reputation
ASR 1K is SP grade routers it has all the feature that a SP may need commonly to cover current and future needs.
Cisco Router are very well know and common CLI enable us to get best resources from the marlet to amanges these routers.
ASR 1K is widely used in the market
We are comfortable with out selection and evaluation process. we do not reget choosing ASR 1K for our cloud network.

Cisco 1000 Series Aggregation Services Routers (ASR 1000) Implementation

Implementation was as per design and all best practice configuration was followed.
  • Third-party professional services
Emircom Cisco GOld partner were enguaged and implremented these routers
Change management was minimal - We implemented ASR Router as part of new Network so no chnage management process was required. only network was in production we follow ITIL Chnage management process.
  • implementation went very well

Our Organization is the biggest carrier in Middle east and thus we always strive for latest technology backed by vendor premium support to ensue our 24x7 Services and Operations. Currently all our Cloud Network Components are backed by Cisco Premium support. Premium support give piece of mind to be able to bet 24x7 TAC support and 4 Hrs RMA delivery.
After first year of passing built phase. we conducted a DR drill on our production network. we found that one of our failoure scenario was not working and that was link failoure between our Border leafs Switches and our ASR router get failed. in this failoure scenarion traffic coming from FAbric to ASR routers was getting blacked holed. Cisco helps us review the Network design and quickly helped us fixing the issue with minor change in design. Cisco support was quite exception in this event.
